What
Is Salt?
Sodium
chloride or common salt is the chemical compound NaCl. Salt occurs
naturally in many parts of the world as the mineral halite and as mixed
evaporites
in salt lakes. Seawater has lots of salt; it contains an
average of 2.6% (by weight)
NaCl, or 26 million metric tons per cubic
kilometer (120 million short tons per cubic
mile, an inexhaustible
supply (note: seawater also contains other dissolved solids;
salt
represents about 77% of the Total Dissolved Solids). Underground salt
deposits are found in both bedded sedimentary layers and domal deposits.
Deposits have been found to have encapsulated ancient microorganisms
including bacteria. Some salt is one the surface, the dried-up residue
of ancient
seas like the famed Bonneville Salt Flats in Utah. Salt even
arrives on earth from
outer space and its presence on the planet Mars
makes scientists think life may
exist there. Conversely, surface salt
depositions and man-made saltworks can be
seen from space.
Sodium chloride crystals are cubic in form. Table salt consists of tiny
cubes tightly
bound together through ionic bonding of the sodium and
chloride ions. The salt
crystal is often used as an example of
crystalline structure. It can be modified by
temperature. Different
types of crystal have different uses, as for food.
It varies in color from colorless, when pure, to white, gray or
brownish, typical of
rock salt (halite). Chemically, it is 60.663%
elemental chlorine (Cl) and 39.337%
sodium (Na). The atomic weight of
elemental chlorine is 35.4527 and that of sodium
is 22.989768.
Properties of salt are collected in the U.S. Occupational Safety and
Health Administration (OSHA) Chemical Sampling Information database.

Sodium chloride is sold in several different particle sizes (gradation)
and forms,
depending on the intended end use. Discrete crystals can be
seen in rock salt
used for deicing. Fine granules are typical of table
salt and even finer popcorn
salt. Kosher salt, pickling salt and ice
cream salt are slightly coarser. Small
compressed pellets are used in
water softeners and large salt blocks are used
as salt licks for
livestock. When viewed under strong magnification, all sodium
chloride is crystalline. Very large cubic crystals, of two, three or more inches
in
size, can be seen in some salt mines. They are transparent and cleave
into
perfect cubes whenstruck with a hard object.
Purity of rock salt produced in North America varies depending on the
type of salt
(evaporated, rock, solar) and on the source. Rock salt
typically ranges between
95% and 99% NaCl, and mechanically evaporated
salt and solar salt normally
exceed 99% NaCl. Evaporated salt made with
purified brine has the highest purity,
in some cases 99.99% NaCl.
Voluntary standards, such as those developed by
the American Society for
Testing and Materials (ASTM), the American Water
Works Association (AWWA)
assure appropriate quality for the intended use.
Mandatory
specifications for food grade, drug/medical and analytical use include
Food Chemicals Codex, U.S. Pharmacopoeia, and Reagent Grade Chemicals.
Special devices, refractometers, are used to measure salinity.
Common salt or sodium chloride is considered by the U.S. Food and Drug
Administration as safe for its intended use as a food additive. This
GRAS
(generally recognized as safe) classification, and the universal
use of sodium
chloride since antiquity, affirms its safety. The Merck
Index refers to sodium
chloride as "not generally considered
poisonous." Many substances in everyday
use can be toxic in high
concentrations, even water. Toxic levels of sodium
chloride are reported
as:
Oral toxicity (The Registry of Toxic Effects of Chemical Substances,
1986):
Human; TDLo: 12,357 mg/kg/23 D-C
Mouse; LD50: 4,000 mg/kg
Rat; LD50: 3,000 mg/kg
Rabbit; LDLo: 8,000 mg/kg
Acute aquatic toxicity (U.S. EPA, Ambient Water Quality Criteria for
Chloride, 1988):
Rana Breviceps (frog); No observed effect concentration (NOEC):
400 mg/L.
Daphnia pulex 48-hour LC50 or EC50: 1,470 mg/L
Daphnia magna (water flea); 48 hour EC50: 3,310 mg/L
Myriophyllum spicatum (water milfoil); Phytotoxicity (EC50
for growth): 5,962 mg/L
Pimephales promealas (fathead minnow); 69-hour LC50: 7,650
mg/L
Lepomis macrochirus (Bluegill) LC50 or EC50: 7,846 mg/L
Anguilla rostrata (American eel) 48-hour LC50 or EC 50:
13,085 mg/L
EPA says that the chlorides of calcium, magnesium and potassium are
generally
more toxic to fresh water species than sodium chloride. Some
Antarctic species
depend on salt to protect them against the cold.

History Of Salt:
Most people probably think of salt as simply that white
granular food seasoning found in a salt shaker on virtually
every dining table.
It is that, surely, but it is far more. It is an essential
element in the diet of not only humans but of animals, and
even of many plants. It is one of the most effective and most
widely used of all food preservatives (and used to preserve
Egyptian mummies as well). Its industrial and other uses are
almost without number. In fact, salt has great current as well
as historical interest, even the subject of humorous cartoons
and poetry and useful in film-making. Sometimes, however, we
need to separate the salt to get the history.
The fact is that throughout history, salt--called sodium
chloride by chemists--has been such an important element of
life that it has been the subject of many stories, fables and
folktales and is frequently referenced in fairy tales. It
served as money at various times and places, and it has been
the cause of bitter warfare. Offering bread and salt to
visitors, in many cultures, is traditional etiquette. It is
used in making pottery. While we have records of the
importance of salt in commerce in Medieval times and earlier,
in some places like the Sahara and Nepal, salt trading today
gives a glimpse of what life may have been like centuries ago.
Salt was in general use long before history, as we know it,
began to be recorded. Some 2,700 years B.C.-about 4,700 years
ago-there was published in China the Peng-Tzao-Kan-Mu,
probably the earliest known treatise on pharmacology. A major
portion of this writing was devoted to a discussion of more
than 40 kinds of salt, including descriptions of two methods
of extracting salt and putting it in usable form that are
amazingly similar to processes used today. Chinese folklore
recounts the discovery of salt. Salt production has been
important in China for two millennia or more. And the Chinese,
like many other governments over time, realizing that everyone
needed to consume salt, made salt taxes a major revenue
source. Nomads spreading westward were known to carry salt.
Egyptian art from as long ago as 1450 B.C. records
salt-making.
Salt was of crucial importance economically. A far-flung trade
in ancient Greece involving exchange of salt for slaves gave
rise to the expression, "not worth his salt."
Special salt rations given early Roman soldiers were known as
"salarium argentum," the forerunner of the English
word "salary." References to salt abound in
languages around the globe, particularly regarding salt used
for food. From the Latin "sal," for example, come
such other derived words as "sauce" and
"sausage." Salt was an important trading commodity
carried by explorers.
Salt has played a vital part in religious ritual in many
cultures, symbolizing immutable, incorruptible purity. There
are more than 30 references to salt in the Bible, using
expressions like "salt of the earth." And there are
many other literary and religious references to salt,
including use of salt on altars representing purity, and use
of "holy salt" by the Unification Church.

Tips For Salt Use:
Besides making foods delicious, it's believed there are more than 14,000
uses of
salt, and our grandmothers were probably familiar with most of them.
Many of
these uses were for simple things around the home before the advent of
modern
chemicals and cleaners. However, many uses are still valid today and a
lot
cheaper than using more sophisticated products.
We thought you might like to share some of these fascinating
applications of salt.
We make no guarantee about the results if you try any of them, but there
must be
something to them since they have been handed down over the years in
many
households. Most of these uses have stood the test of time.
The most familiar use of salt undoubtedly is in the kitchen and on the
dining table.
Salt accents the flavor of meat, brings out individuality of vegetables,
puts "oomph"
into bland starches, deepens the flavor of delicate desserts and
develops flavor
of melons and certain other fruits. No other seasoning has yet been
found that can
satisfactorily take the place of salt. But there are other uses around
the home, too.
Salt is an excellent cleaning agent, by itself or in combination with
other
substances.
A solution of salt and turpentine restores the whiteness to yellowed
enameled
bathtubs and lavatories. A paste of salt and vinegar cleans tarnished
brass or
copper. a strong brine poured down the kitchen sink prevents grease
from
collecting and eliminates odors.
Salt helps destroy moths and drives away ants. A dash of salt in laundry
starch
keeps the iron from sticking and gives linen and fine cottons a glossy,
like-new
finish. A thin paste of salt and salad oil removes white marks caused by
hot
dishes or water from wooden tables.
A box of salt is an important item in many bathrooms. In mild solutions,
it makes an
excellent mouthwash, throat gargle or eye-wash; it is an effective
dentifrice; it is an
effective antiseptic; and it can be extremely helpful as a massage
element to
improve complexion.
We offer these other tips:
Kitchen:
Boiling Water - Salt added to water makes the water boil at a
higher
temperature, thus reducing cooking time. (It does not make the water
boil faster.)
Peeling eggs - Boiling eggs in salted water will make eggs peel
easily.
Poaching eggs - Poaching eggs over salted water helps set the egg
whites.
Testing egg freshness - Place the egg in a cup of water to which
two
teaspoonfuls of salt has been added. A fresh egg sinks; a doubter will
float.
Preventing browning - Apples, pears and potatoes dropped in cold,
lightly
salted water as they are peeled will retain their color.
Shelling pecans - Soaking pecans in salt water for several hours
before
shelling will make nut meats easier to remove.
Washing spinach - If spinach is washed in salted water, repeated
cleanings
will not be necessary.
Preventing sugaring - A little salt added to cake icings prevents
them from
sugaring.
Crisping salads - Salting salads immediately before serving will
keep them
crisp.
Improving boiled potatoes - Boiled potatoes will be given a fine,
mealy
texture by sprinkling with salt after draining, then returning them to
the pan and
shaking them back and forth quickly to get rid of the excess moisture.
Cleaning greasy pans - The greasiest iron pan will wash easily if
you put a
little salt in it and wipe with paper.
Cleaning stained cups - Rubbing with salt will remove stubborn
tea or coffee
stains from cups.
Cleaning ovens - Salt and cinnamon take the "burned
food" odor away from
ovens and stove burners. Sprinkle spills while oven and burners are
still hot;
when dry, remove the salted spots with a stiff brush or cloth.
Cleaning refrigerators - Salt and soda water will clean and
sweeten the inside
of your refrigerator. It won't scratch enamel either.
Extinguishing grease fires - Salt tossed on a grease fire on the
stove or in the
oven will smother flames. Never use water; it will only spatter the
burning grease.
Improving coffee - A pinch of salt in coffee will enhance the
flavor and remove
the bitterness of over-cooked coffee.
Improving poultry - To improve the flavor of poultry, rub the
fowl inside and out
with salt before roasting.
Removing pinfeathers - To remove pinfeathers easily from a
chicken, rub the
chicken skin with salt first.
Cleaning tarnished silverware - Rub tarnish with salt before
washing.
Cleaning copper pans - Remove stains on copper pans by salting
area and
scouring with a cloth soaked in vinegar.
Cleaning coffee pots - Remove bitterness from percolators and
other coffee
pots by filling with water, adding four tablespoons of salt and
percolating or
boiling as usual.
Removing onion odors from hands - Rub fingers with salt moistened
with
vinegar.
"Sweetening" containers - Salt can "sweeten"
and deodorize thermos bottles
and jugs, decanters and other closed containers.
Cleaning sink drains - Pour a strong salt brine down the kitchen
sink drain
regularly to eliminate odors and keep grease from building up.
Brightening cutting boards - After washing them with soap and
water, rub
bread and cutting boards with a damp cloth dipped in salt; the boards
will be
lighter and brighter.
Fixing oversalted soups - If soup has been oversalted, cut up a
raw potato or
two and drop into the soup. The potato will absorb the salt.
Cleaning dried-on egg - Salt not only makes eggs taste better,
but it makes
"eggy" dishes clean easier. Sprinkle salt on dishes right
after breakfast; it makes
them a whiz to clean when you have time.
Preventing food from sticking - Rub a pancake griddle with a
small bag of
salt to prevent sticking and smoking. Sprinkle a little salt in the
skillet before frying
fish to prevent the fish from sticking. Sprinkle salt on washed
skillets, waffle iron
plates or griddles, heat in a warm oven, dust off salt; when they are
next used,
foods will not stick.
Preventing mold - To prevent mold on cheese, wrap it in a cloth
dampened
with saltwater before refrigerating.
Whipping cream and beating egg whites - By adding a pinch of
salt, cream
will whip better and egg whites will beat faster and higher.
Keeping milk fresh - Adding a pinch of salt to milk will keep it
fresh longer.
Setting gelatin - To set gelatin salads and desserts quickly,
place over ice that
has been sprinkled with salt.
Cleaning:
Cleaning brass - Mix equal parts of salt, flour and vinegar to
make a paste, rub
the paste on the brass item, leave on for an hour or so, then clean with
a soft cloth
or brush and buff with a dry cloth.
Cleaning wicker - To prevent yellowing, scrub wicker furniture
with a stiff brush
moistened with warm saltwater and allow to dry in the sun.
Cleaning grease spots on rugs - Some grease spots can be removed
with a
solution of one part salt and four parts alcohol and rubbing hard but
carefully to
avoid damage to the nap.
Extending broom life - New brooms will wear longer if soaked in
hot saltwater
before they are first used.
Removing wine stains - If wine is spilled on a tablecloth or rug,
blot up as much
as possible and immediately cover the wine with salt, which will absorb
the
remaining wine. Later rinse the tablecloth with cold water; scrape up
the salt from
the rug and then vacuum the spot.
Removing rings from tables - White rings left on tables from wet
or hot dishes
or glasses can be removed by rubbing a thin paste of salad oil and salt
on the
spot with your fingers, letting it stand an hour or two, then wiping it
off.
Restoring sponges - Give sponges new life by soaking them in cold
saltwater
after they are washed.
Settling suds - If a washing machine bubbles over from too many
suds, sprinkle
salt on the suds to reduce them.
Brightening colors - Wash colored curtains or washable fiber rugs
in a
saltwater solution to brighten the colors. Brighten faded rugs and
carpets by
rubbing them briskly with a cloth that has been dipped in a strong
saltwater
solution and wrung out.
Removing perspiration stains - Add four tablespoons of salt to
one quart of
hot water and sponge the fabric with the solution until stains
disappear.
Brightening yellowed cottons or linens - Boil the yellowed items
for one
hour in a salt and baking soda solution
Removing blood stains - Soak the stained clothing or other cloth
item in cold
saltwater, then launder in warm, soapy water and boil after the wash.
(Use only on
cotton, linen or other natural fibers that can take high heat.)
Removing mildew or rust stains - Moisten stained spots with a
mixture of
lemon juice and salt, then spread the item in the sun for bleaching; and
finally,
rinse and dry.
Color-matching nylons - Good nylons that don't have a match can
be made
the same color by boiling them a few minutes in a pan of lightly salted
water.
Fixing sticking iron - Sprinkle a little salt on a piece of paper
and run the hot
iron over it to remove rough, sticky spots.
Health & Beauty:
Gargling - Stir 1/2 teaspoon salt in an 8-ounce glass of warm
water for use as a
gargle for sore throats.
Cleaning teeth - Mix one part salt to two parts baking soda after
pulverizing the
salt in a blender or rolling it on a kitchen board with a tumbler before
mixing. It
whitens teeth, helps remove plaque and it is healthy for the gums.
Washing mouth - Mix equal parts of salt and baking soda as a
mouth wash that
sweetens the breath.
Bathing eyes - Mix 1/2 teaspoon of salt in a pint of water and
use the solution to
bathe tired eyes.
Reducing eye puffiness - Mix one teaspoon of salt in a pint of
hot water and
apply pads soaked in the solution on the puffy areas.
Relieving tired feet - Soak aching feet in warm water to which a
handful of salt
has been added. Rinse in cool water.
Relieving bee stings - If stung, immediately wet the spot and
cover with salt to
relieve the pain.
Treating mosquito and chigger bites - Soak in saltwater, then
apply a mixture
of lard and salt.
Treating poison ivy - Soaking the exposed part in hot saltwater
helps hasten
the end to poison ivy irritation.
Relieving fatigue - Soak relaxed for at least ten minutes in a
tub of water into
which several handfuls of salt has been placed.
Removing dry skin - After bathing and while still wet give
yourself a massage
with dry salt. It removes dead skin particles and aids the circulation.
Applying facial - For a stimulating facial, mix equal parts of
salt and olive oil
and gently massage the face and throat with long upward and inward
strokes.
Remove mixture after five minutes and wash face.
Removing tattoos -CAUTION-
This is a medical procedure that can be done
only by a physician. It is called salabrasion and requires several
treatments by
rubbing salt on the tattoo. Healing is required between treatments, but
there is
virtually no scarring.
Other Uses:
Extinguishing grease fires - Keep a box of salt handy at your
stove and oven
and if a grease fire flares up, cover the flames with salt. Do not use
water on
grease fires; it will splatter the burning grease. Also a handful of
salt thrown on
flames from meat dripping in barbecue grills will reduce the flames and
deaden
the smoke without cooling the coals as water does.
Drip-proofing candles - Soak new candles in a strong salt
solution for a few
hours, then dry them well. When burned they will not drip.
Removing soot - Occasionally throw a handful of salt on the
flames in your
fireplace; it will help loosen soot from the chimney and salt makes a
bright yellow
flame.
Cleaning fish tanks - Rub the inside of fish tanks with salt to
remove hard water
deposits, then rinse well before returning the fish to the tank. Use
only plain, not
iodized, salt.
Invigorating goldfish - Occasionally add one teaspoon of salt to
a quart of
fresh water at room temperature and put your goldfish in for about 15
minutes.
Then return them to their tank. The salt swim makes them healthier.
Cleaning flower vases - To remove deposits caused by flowers and
water,
rub with salt; if you cannot reach the deposits to rub them, put a
strong salt solution
in the vase and shake, then wash the vase with soap and water.
Keeping cut flowers fresh - A dash of salt added to the water in
a flower vase
will keep cut flowers fresh longer.
Holding artificial flowers - Artificial flowers can be held in an
artistic
arrangement by pouring salt into the container, adding a little cold
water and then
arranging the flowers. The salt will solidify as it dries and hold the
flowers in place.
Keeping patios weed-free - If weeds or unwanted grass come up
between
patio bricks or blocks, carefully spread salt between the bricks and
blocks, then
sprinkle with water or wait for rain to wet it down.
Killing poison ivy - Mix three pounds of salt with a gallon of
soapy water and
apply to leaves and stems with a sprayer.
Keeping windows frost-free - Rub the inside of windows with a
sponge
dipped in a saltwater solution and rub dry; the windows will not frost
up in
sub-freezing weather. Rubbing a small cloth bag containing salt that has
been
moistened on your car's windshield will keep snow and ice from
collecting.
Deicing sidewalks and driveways - Lightly sprinkling rock salt on
walks and
driveways will keep snow and ice from bonding to the pavement and allow
for
easy removal. Don't overdo it; use the salt sensibly to avoid damage to
grass
and ornamentals.
Deodorizing shoes - Sprinkling a little salt in canvas shoes
occasionally will
take up the moisture and help remove odors.
Salt
and Good Health:
Salt is essential not only to life, but to good health. Human blood
contains 0.9%
salt (sodium chloride) -- the same concentration as found in United
States
Pharmacopeia (USP) sodium chloride irrigant commonly used to
cleanse
wounds. Salt maintains the electrolyte balance inside and outside of
cells. Most
of our salt comes from foods, some from water. Doctors often
recommend
replacing water and salt lost in exercise and when working outside.
Wilderness
hikers know the importance of salt tablets to combat hyperthermia.
Oral
rehydration involves replacing both water and salt. Expectant mothers
are
advised to get enough salt. Increased salt intakes have been used
successfully
to combat Chronic Fatigue Syndrome. Dramatic deficiencies (e.g.
"salt starvation"
in India) or "excessive" sodium intakes have been associated
with other
conditions and diseases, such as hypertension and stomach cancer.
Testing the
salinity of perspiration is a good test for cystic fibrosis; scientists
suspect that
cystic fibrosis is caused by a deformed protein that prevents chloride
outside
cells from attracting needed moisture.
The National Academy of Sciences recommends that Americans consume
a
minimum of 500 mg/day of sodium to maintain good health. Individual
needs,
however, vary enormously based on their genetic make-up and the way they
live
their lives. While individual requirements range widely, most Americans
have no
trouble reaching their minimum requirements. Most consume
"excess" sodium
above and beyond that required for proper bodily function. The kidneys
efficiently
process this "excess" sodium in healthy people. Experimental
studies show that
most humans tolerate a wide range of sodium intakes, from about 250
mg/day to
over 30,000 mg/day. The actual range is much narrower. Americans
consume
about 3,500 mg/day of sodium; men more, women less. The very large
percentage
of the population consumes 1,150- 5,750 mg/day which is termed the
"hygienic
safety range" of sodium intake by renowned Swedish hypertension
expert
Dr. Björn Folkow. Chloride is also essential to good health. Every
substance,
including water, can be toxic in certain concentrations and amounts;
this is not a
significant concern for dietary salt.
Salt and Cardiovascular Health
For 4,000 years, we have known that salt intakes can affect blood
pressure
through signals to the muscles of blood vessels trying to maintain blood
pressure
within a proper range. We know that a minority of the population can
lower blood
pressure by restricting dietary salt. And we know that elevated blood
pressure,
hypertension, is a well-documented marker or risk factor for
cardiovascular
events like heart attacks and strokes, a silent killer.
Cardiovascular events are
a major cause of premature death and cost Americans more than $300
billion
every year in increased medical costs and lost productivity. Reducing
blood
pressure can reduce the risk of a heart attack or stroke depending
on how its
done.
Some have suggested that since salt intakes are related to blood
pressure, and
since cardiovascular risks are also related to blood pressure, that,
surely, salt
intake levels are related to cardiovascular risk. This is the salt
hypothesis or
sodium hypothesis. Data are needed to confirm or reject
hypotheses.
Blood pressure is a sign. When it goes up (or down) it indicates an
underlying
health concern. Changes result from many variables, often still
poorly-understood.
High blood pressure is treated with pharmaceuticals and with lifestyle
interventions
such as diet and exercise. The anti-hypertensive drugs are all approved
by
regulatory authorities such as the U.S. Food and Drug Administration. To
be
approved, these drugs must prove they work to lower blood pressure.
Whether
they also work to lower the incidence of heart attacks and strokes has
not been
the test to gain approval (it would take too long to develop new drugs),
but the
National Heart, Lung and Blood Institute has invested heavily in such
health
outcomes studies.
Salt and Human Health:
of life, being one of the elements the human body cannot do without. It is present
for 2/3 in the extra-cellular liquids and for 1/3 it is primarily fixed within the bones.
Every imbalance in the extra-cellular hydration is connected to anomalies in the
presence of sodium (that is, of salt). In the US, the consumption of sodium is on an
average about 3 grams a day, corresponding to the ingestion of 7-8 grams of salt.
A certain amount of salt must be incorporated daily in our diet, not only because
it is very rapidly eliminated by our organism and also because it enhances the
taste of our food, but above all because the identification of salty taste triggers the
production of the saliva and the gastric juices, essential for food digestion. In
addition, the presence of sodium and chlorine is essential in the digestive
processes, since they are both present in the gastric juices, in the saliva, in the
pancreatic juice and in the bile. The sodium and the chlorine act then at different
levels, along the digestive track, since sodium contributes to the absorption of
glucides, while chlorine, in the form of hydrochloric acid, is essential for the
digestion of solids.
The kidneys regulate the sodium balance. They are able to quickly adjust the
sodium balance, when the quantity of salt varies between 1 and 16 grams a day.
Under these conditions, there are no variations in the extra-cellular volume or in
body weight. With quantities of salt higher than 16 grams a day, kidney adjustment
requires 3-5 days, during which time an increase in the extra-cellular volume and
in body weight is evident. After this period of time, the two values stabilize
themselves to the new acquired levels.
Sodium chloride can also be used as treatment:
In cases of glandular problems causing obesity, for instance, salt baths are very
useful, even in cases of hypo function or hyper function of the thyroid.
The application of dry or wet salt compresses reduces the excess liquid
present in the tissues.
For relief of swollen and sore feet, immerse them in a basin of warm water with a
handful of salt.
To reduce bags under the eyes apply compresses soaked in a teaspoon of
salt dissolved in a 4 cups of warm water.
Gargling with some salt and bicarbonate of soda dissolved in water disinfects
the mouth, leaving a fresh breath.
The inhalation of salt-water steam through the nose can relieve bothersome
cases of phlegm or of inflammation of the respiratory mucosa.
For an all natural peeling, try mixing a cream with honey and salt and massage
it gently over the interested parts of the face.
Balneotherapy
- Healing with Water
This
excerpt is reprinted from Healing Spriings, The Ultimate Guide to Taking
the
Waters, by Nathaniel Altman.
One of the most important activities that takes place at a traditional
spa is
balneotherapy, a natural approach to health and healing that uses hot
spring
water, gases, mud, and climatic factors (such as heat) as therapeutic
elements.
Simple Solution: In addition to bathing, modalities such as
hydrotherapy, mud
therapy, physical therapy, massage, steam baths, physical exercises,
inhalation
of water vapor, and drinking mineral water are often used as part of a
complex
therapy for both health and preservation and treating disease.
Over the past four centuries, the science of balneology has evolved into
a
medical specialty in Europe and Japan, where special courses in
balneotherapy
are offered to both physicians and nurses by major medical schools.
Doctors
believe that thermal springs facilitate healing in a number of important
ways.
Eight ways Balneotherapy Heals:
* Bathing in hot springs gradually increases the temperature of the
body, thus
killing harmful germs and viruses.
* Thermal bathing increases hydrostatic pressure on the body, thus
increasing
blood circulation and cell oxygenation. The increase in
blood flow also helps
dissolve and eliminate toxins from the body.
* Hot springs bathing increases the flow of oxygen-rich blood throughout
the body,
bringing improved nourishment to vital organs and tissues.
* Bathing in thermal water increases body metabolism, including
stimulating the
secretions of the intestinal tract and the liver, aiding
digestion.
* Repeated hot springs bathing (especially over 3- to 4- week period)
can help
normalize the functions of the endocrine glands as well as
the functioning of the
body's autonomic nervous system.
* Trace amounts of minerals such as carbon dioxide, sulfur, calcium,
magnesium,
and lithium are absorbed by the body and provide healing
effects to various
body organs and system. These healing effects can include
stimulation of the
immune system, leading to enhanced immunity; physical and
mental relaxation;
the production of endorphins; and normalized gland
function.
* Mineral springs contain high amounts of negative ions, which can help
promote
feelings of physical and psychological well-being.
* The direct application of mineralized thermal waters (especially those
containing
sulfur) can have a therapeutic effect on diseases of the
skin, including psoriasis,
dermatitis, and fungal infections. Some mineral waters are
also used to help the
healing of wounds and other skin injuries.
Indications for Balneotherapy:
Over the several hundred years during which the science of medical
balneology
has developed, physicians have been able to identify the health
conditions that
can best be treated by healing springs. The following list of
indications for
balneotherapy is based on the research of Yuko Agishi, M.D.
CHRONIC DISEASES
Chronic rheumatic diseases
Functional recovery of central and peripheral neuroparalysis
Metabolic diseases, especially diabetes, obesity, and gout
Chronic gastrointestinal diseases

Circulatory diseases, especially moderate or mild hypertension
Peripheral circulatory diseases (affecting the hands and feet)
Chronic skin diseases
Psychosomatic and stress-related diseases
Autonomic nervous system dysfunction
Vibration disorder (a middle ear disorder affecting balance)
Sequela of (conditions resulting from) trauma
Chronic gynecological diseases
CONTRAINDICATIONS
If you have any illnesses or diseases, or are pregnant, consult with
your physician
before using spa therapy.
CAUTIONS
Avoid soaking in a hot spring alone, caution and the elderly should use
with
caution, don't use a spa if you are under the influence of alcohol or
drugs,
especially heart medications, don't overheat, drink plenty of cool

Balneotherapy
Balneotherapy is the art of water therapy, and one of aromatherapy's
best friends.
There is nothing quite so soothing and relaxing as a leisurely soak in a
hot bath.
As the warmth of the water cradles your physical body, providing relief
from the
constant pull of gravity, your psyche is refreshed and restored, the
weight of the
world momentarily lifted. Add a few drops of well-selected essential
oils and you
approach nirvana.
Water is nature's greatest and most effective solvent. It acts as a
liquid
suspension, carrying a variety of minerals and chemicals, depending on
its
source. When we immerse our bodies in a warm bath, our skin rapidly
begins to
absorb chemicals that are suspended in the water. These chemical
components
can make their way to our bloodstream in as little as 2 to 15 minutes.
It will take a
normally healthy person from half an hour to three hours to eliminate
most of these
chemicals through the expired breath and urine. In unhealthy or obese
people,
this process may take up to 10 hours. That is why adding essential oils
to a bath
is such an effective aromatherapy treatment.
The premise of balneotherapy is built on this solvency. Just as we
absorb the
essential oils we intentionally add to the water, we absorb a variety of
other
chemicals and minerals suspended in our water. No two waters are exactly
the
same. Spring waters, often thought of as pure, actually contain a
variety of
minerals. It is the presence of these minerals, from the depths of the
earth, that
makes certain spring waters highly valued for their curative properties.
The amazing virtues of water have been sung throughout the ages. Ancient
myths
featured countless sea nymphs, mermaids, and water goddesses. It's no
wonder
that most ancient gods and goddesses associated with water were believed
to
be sources of life, fertility, and fecundity. Water is our element. We
most likely
evolved from aquatic creatures -- and in any event, our first months of
life were
spent floating in an amniotic bath. In our dreams water symbolizes the
ebb and
flow of our emotions. We use water for cleansing, refreshing, and
relaxing. Water
is the basis for our body's evaporative cooling system. It flushes out
toxic wastes,
plumps up our cells, and lubricates our moving parts. Water is crucial
to our
survival. Without it we would literally dry up and blow away.
A Brief History of the Bath
Although the Romans may not have invented the bath, they raised bathing
to a
high art. Roman citizens lingered for hours in communal hot baths, where
they
lavish baths wherever they found natural hot springs. The remains of
Roman
baths are still evident throughout Europe, the Mideast, and North
Africa.
The Roman reverence for bathing has survived in Turkey, where patrons
still visit
public baths to be soaped, steamed, and scrubbed clean by
attendants.
Meanwhile, a highly ritualized bathing culture has evolved in Japan as
well. Whole
towns exist as destination resorts around Japanese natural hot springs.
The
harried Japanese make annual visits to these springs, and in between
find time
for frequent visits to the "Sento" -- the local communal
hot-tub house. Japanese
homes are for the most part poorly heated, and the family bath becomes
an
important source of warmth in winter.
With the fall of the Roman Empire, bathing fell out of favor in Europe.
For the next
few centuries the practice was considered suspect and unhealthy,
immersion a
frightening and distasteful experience. Washing was an unpleasant and
infrequent
necessity, to be carried out quickly and furtively, with a basin of cold
water.
Water Therapy
Water therapy as practiced today was introduced in Austria in the 19th
century by
the Reverend Father Sebastian Kneipp. Father Kneipp believed in the
healing
properties of water and prescribed treatments that included drinking
mineral
waters, soaking in hot springs, taking cold showers, and walking
barefoot in the
early-morning dew. Healing spas that subscribed to Father Kneipp's
philosophy
sprang up all over Europe, and "taking the waters" became a
popular social
pastime for the rich and privileged.
Today health spas abound throughout the United States, Europe, and
the
Mediterranean. Modern spas have evolved beyond mere mineral-water
treatments to offer many other complementary therapies as well as
physical
fitness, relaxation training, and nutritional counseling. Aromatherapy
has been
universally adopted as a valuable synergistic component of most spa
therapies.
You can create your own spa experience with just a few essential oils
and a tub of
hot water. An aromatherapy bath is the ultimate luxury. Experiment with
3 to 5 drops
of several different, complementary oils, adjusting the total amount to
suit your
individual taste. You can add the oils directly to the bath or, for
added luxury,
disperse them in a cup of milk first. Essential oils combine well with
all other bath
additives. Add Epsom salts, sea salts, and algae to mineralize the water
and
increase buoyancy. Add oatmeal or honey to soothe and nourish the skin.
Add
bicarbonate of soda to "soften" the water. Add fresh or dried
herbs and flower
petals for their aesthetic and therapeutic qualities.

Salt
and Human Nutrition:
Sometimes the two terms, "salt" and
"sodium" are used interchangeably, but
technically this is not correct. "Salt" is sodium chloride. By
weight, it is 40% sodium
and 60% chloride. Sodium is an essential nutrient, a mineral that the
body cannot
manufacture itself but which is required for life itself and good
health. Because of
sodium's importance to your body, several interacting mechanisms guard
against
under-consumption of salt and its threat to your body's nerves and
muscles and
interference with the sodium-potassium "pump" which adjusts
intra- and
extra-cellular pressures. If your salt intake varies widely, these
mechanisms
activate to assure that your body remains healthy, maintaining a
relatively
constant blood pressure. Chloride, too, is essential to good health. It
preserves
acid-base balance in the body, aids potassium absorption, supplies the
essence
of digestive stomach acid, and enhances the ability of the blood to
carry carbon
dioxide from respiring tissues to the lungs. Salt should be part of
every family's
food storage program. Salt has been a valuable weapon in our public
health
campaign against iodine deficiency disorders (IDD), iodizing salt has
virtually
eliminated IDD in North America and many other areas although the World
Health
Organization has targeted elimination of IDD globally as a top priority.
Where
public health authorities do not fluoridize water, adding fluoride to
salt is common
as in France, Switzerland and Latin America.
Years ago we thought that different societies have wide variations in
salt intake.
Current research shows that where salt is readily available, the vast
majority of the
world's population chooses to consume about 6-10 grams of salt a day.
Including
naturally occurring sodium in foods, people worldwide consume about
3,500
milligrams (mg) of sodium, Americans included. Some remote primitive peo
dietary sodium do have almost unbelievably small levels of sodium
intakefar
below that judged by the National Academy of Sciences to be safe for
Americans. But for the rest of the world, our average intakes are
typical. The National
Academy of Sciences recommends that Americans consume a minimum of
500
mg/day of sodium. The European Union Population Reference Intake for
males
aged 18 years (an "acceptable range of intakes") is 575-3500
mg. Nutrition is
important to good health. Salt is part of a healthy diet, a fact
increasingly
recognized by the public.
