Usefulness of Iodine
Disclaimer: Though Dr.
Jarvis refers to the many qualities of Lugol's Solution it is offered for sale
only as a "talisman". We are aware of its regular use in the past as a
general purpose traditional disinfectant however, we make no claims with respect
to its efficacy for any purpose whatsoever. In some states a doctor's
prescription is required to purchase Lugol's Solution of Iodine.
An Excerpt from D.C. Jarvis, MD
FOLK MEDICINE IN VERMONT is interested in three
R's-Resistance, Repair, and Recovery. First the individual asks himself whether
his resistance to disease is as it should be. Next, is he able to repair tissue
injury due to accident should it occur? Finally, if sickness should come, is his
body able to bring about recovery? Somehow during the passing years he has
learned that iodine is related to the ability to resist disease.
Iodine is necessary for the thyroid gland's proper performance of its work. The
human thyroid gland is located in the front of the lower part of the neck. All
the blood in the body passes through the thyroid gland every 17 minutes. Because
the cells making up this gland have an affinity for iodine, during this
17-minute passage the gland's secretion of iodine kills weak germs that
may have gained entry into the blood through an injury to the skin, the lining
of nose or throat, or through absorption of food from the digestive tract.
Strong, virulent germs are rendered weaker during their passage through the
thyroid gland. With each 17 minutes that rolls around they are made still weaker
until finally they are killed if the gland has its normal supply of iodine. If
it does not, it cannot kill harmful germs circulating in the blood as Nature
intended it should.
It is well established that the iodine content of
the thyroid gland is dependent upon the iodine available in the food and water
intake of the individual. If the iodine intake is low the gland is deprived of
an element it needs to do its work.
We learn in Vermont folk medicine, however, that
this gland performs other functions besides killing harmful germs in the blood.
The first is the rebuilding of energy with which to do the day's work. There is
a definite relationship be-tween the amount of energy you have and your iodine
intake. The first question in the presence of a condition of depleted energy is,
Is the soil of the state in which one lives iodine-poor? Second, is the
deficiency being made up by supple-mentary means? All soils containing granite
are iodine-poor and Vermont is one of them. This fact is very important to
people living in Vermont and well may be important to those living elsewhere.
When energy and endurance run low in relation to doing the day's work, then the
taking of iodine needs to be considered.
A second function of iodine is to calm the body
and relieve nervous tension. When nervous tension runs high there is
irritability and difficulty in sleeping well at night, and the body is
continually on a combat basis, organized for fight and flight. All these points
stress a body need for iodine to lessen nervous tension, relax the body and
enable it to or-ganize for peace and quiet, by the building and storing of body
reserves against time of need. I have learned through Vermont folk medicine that
it is possible to repeatedly change an irritable, impatient, and restless child
under ten years of age into a calm, patient individual within two hours' time by
giving one drop of Lugol's solution of iodine by mouth in a vegetable or fruit
juice or in a glass of water made acid in reaction by adding a teaspoonful of
apple cider vinegar. I have repeatedly prescribed this in order to make it
possible for a mother of a racehorse-type little boy or girl to be able to live
comfortably with the child. I have never seen it fail to calm down a nervous
A third function of iodine in the human body
relates to clear thinking. The mind simply works better when the body is
supplied the iodine it needs.
Then there is the matter of the storing of unwanted fat. Iodine is one of the
best oxidizing catalysts we have. A catalyst is the match which touches off in
the body the fire that burns up the food we take in each day. If this food is
not properly burned off, it may be stored as unwanted fat.
Now while the thyroid gland helpfully stores
iodine from the blood passing through it every 17 minutes, the gland may also be
made to lose that stored iodine if, for example, we take in drinking water to
which chlorine is added, or use too much sodium chloride, whose common name is
table salt. There is a well-known law of halogen displacement. The halogen group
is made up as follows:
The critical activity of any one of these four
halogens is in inverse proportion to its atomic weight. This means that any one
of the four can displace the element with a higher atomic weight, but cannot
displace an element with a lower atomic weight. For example, fluorine can
displace chlorine, bromine and iodine because fluorine has a lower atomic weight
than the other three. Similarly, chlorine can displace bromine and iodine
because they both have a higher atomic weight. Likewise, bromine can displace
iodine from the body because iodine has a higher atomic weight. But a reverse
order is not possible. A knowledge of this well-known chemical law brings us to
a consideration of the addition of chlorine to our drinking water as a purifying
agent. We secure a drinking water that is harmful to the body not because of its
harmful germ content but because the chlorine content now causes the body to
lose the much-needed iodine.
Because we may live in an iodine-poor area;
because drinking water may be treated with chlorine; because we may be sick too
often, lack energy and endurance, develop nervous tension, lack the ability of
clear thinking, and accumulate unwanted fat, how shall we go about bringing up
the iodine content of the body to the point needed?
There are three ways:
1. Eating foods which analysis has shown are particularly rich in iodine. Among
these are: all food out of the ocean, radishes, asparagus, carrots, tomatoes,
spinach, rhubarb, potatoes, peas, strawberries, mushrooms, lettuce, bananas,
cabbage, egg yolk, and onions.
2. Painting a small area of the body with tincture of iodine.
3. Taking preparations known to be rich in iodine. One of these is cod-liver
oil. Another is Lugol's solution of iodine. Still another is the kelp tablets
In 1880 a French physician named Lugol originated
a solution which contains 5 per cent of elemental iodine in a 10 per cent
solution of potassium iodide. It has been used steadily ever since it was
When used to maintain the iodine content of the
body the dose is small and is taken only on certain days of the week. When the
mineral content of the body is analyzed, only a trace of iodine is found. Ten
drops of iodine represent more iodine than is found in the entire body. For this
reason, the dose of Lugol's solution of iodine is one or two drops, depending on
your body weight. If you weigh 150 pounds or less, for example, your dose
to maintain the normal iodine content of the body is one drop, taken at one meal
on Tuesday and Friday of each week. If you weigh more than 150 pounds, the dose
should be two drops instead of one. It is useful to remember that the human body
works on the minimum of anything it needs. If there should be a rise in sickness
in the area where you live, it would be well to take the Lugol's solution three
times a week instead of two, on Monday, Wednesday, and Friday, for the purpose
of storing up reserve.
How is the drop of the solution to be taken, on
the directed days? In general, medical men prescribe iodine to be taken on an
empty stomach, preferably 20 minutes before food is taken. During the passing
years Vermont folk medicine has worked out a different plan and it is one I like
to follow. It has been referred to in another connection elsewhere in this book.
To repeat, adding one teaspoonful of apple cider vinegar to a glass of water to
make the water acid in reaction, holding the medicine dropper horizontal in
order to get a maximum drop, one drop of the Lugol's solution is added to the
mixture. The contents are stirred with a spoon and sipped through the course of
the meal, as one would drink a cup of coffee or tea.
In relation to supplemental use of iodine, my
studies of certain dairy herds has revealed interesting evidences of the
relationship between host and microorganisms, viruses, insects, and other
parasites .With one herd the veterinary bill had generally run $150.00 and
sometimes more a year. At my suggestion, three drops of Lugol's solution of
iodine was added to the daily four ounces of apple cider vinegar. Thereafter it
was only neccessary to call the veterinary once in a period of eight months, to
see a sick cow. In contrast to this, another herd, to which Lugol's solution was
not given, had plenty of sick-ness. In an 8-month period it was necessary to
spend $50.00 for penicillin in order to save seriously sick cows.
I have observed that lice will leave the hide of
a cow that receives apple cider vinegar and iodine; also that flies will not
bite the cows when they are on pasture, though flies will and do bite young
cattle not receiving the apple cider vinegar and iodine.
In a herd troubled with abortions-evidence of the work of the Bru celia abortus
microorganism which grows on an alkaline medium and causes contagious abortion
in cattle called Bang's disease, or brucellosis-abortions promptly stopped when
each feeding ration received a supplemental three drops of Lugol's solution of
iodine to each two ounces of the apple cider vinegar.
While studying selected herds, I became
interested in the problem of cattle grubs. These are the larvae, or maggots, of
the heel fly. The adult fly does not bite or sting, but it produces great
fear and is a serious annoyance to the cattle. Eggs are deposited in a row
attached to a single hair of a cow's heel during the first sunny days of spring.
The eggs incubate and hatch in three or four days and the newly hatched maggots
penetrate the hide of the cow, causing itching and a flow of serum that mats the
hair. The young grubs then work their way upward between the muscles and may be
found in a few months in the body cavities. They continue to burrow along the
surface of the paunch, intestines, and other internal organs. At certain times
many of them are found in the wall of the esophagus, leading from the mouth to
the stomach. During the fall and winter the grubs will finally come to the top
of the back and lie just under the hide. Each grub cuts a hole through the hide
to the surface to get the air which it now needs, and to permit it to escape
when ripe. The period spent beneath the hide usually runs from 30 to 90 days.
These grubs emerge from the hide dur-ing February and March, dropping to the
ground to hatch into heel flies. In 18 to 80 days after escaping from the back
of the cow, the adult fly hatches and is ready to mate within a half hour.
My object was to rout these cattle grubs by means
of the apple cider vinegar and iodine combination; this would demonstrate, to me
at least, what the combination would do in the way of making the body as a host
unsuitable soil for the development and continuing existence of microorganisms,
viruses, insects, and other parasites.
During one year's time only ten grubs were
discovered on the backs of a herd of 45 registered Jersey cows. Usually these
grubs are a little larger round than a pencil, but these ten grubs had such hard
going in the cows' bodies against the vinegar and iodine that they were no
larger around than toothpicks. I observed further with reference to a ration
supplement high in iodine value that when it was used, the bacterial count of
the milk went down; when iodine was dis-continued, the count went up but could
be driven down again immediately with resumption of the iodine.
From Dr. William Weston of
South Carolina and his experience with race horses wintered there, I gained
interesting and valuable insight into the value of iodine in the body, and its
relation to endurance.About 100 race horses are wintered where he lives. Two
years previous to a visit I paid him, the man in charge of the horses came
to him saying that a horse was under his care which had everything it takes to
win the Kentucky Derby. If they could just learn precisely how to feed this
horse to maintain its speed capability, he believed the horse would have an
outstanding racing season. Would Dr. Weston help him by planning the feeding of
Dr. Weston was greatly interested and consented
to do so As a first step he asked for samples of any and all foods given the
horse. The samples were analyzed at the South Carolina Food Research Laboratory.
As a result of the analysis, Dr. Weston advised increasing the iodine content of
the ration by incorporating into it foods specifically rich in iodine.
This was done. In the ensuing season the horse won every race in which it was
As a result of the experience, two wealthy
race-horse owners invited Dr. Weston to come to their horse farms to discuss the
feeding of their stock. Again iodine-rich foods were added to the usual rations,
with the same result; every horse fed on iodine-rich diet won every race in
which it was entered. This seems to be a complete demonstration of the relation
of iodine to energy and endurance. Subsequently, Dr. Weston sent me a copy of a
letter addressed to him as chairman of the South Carolina Food Research
Commission. It well illustrates the need of observing the obligation to Nature
which must be observed by a daily intake of iodine. The letter ran as follows:
Dear Dr. Weston:
Now that we have reached the halfway mark of this racing season, I should like
to tell you some of our observations of the results of wintering our horses in
South Carolina, and feeding them your home grown feeds.
After six years of experiment with several hundred horses, we are more convinced
than ever that your foods, abundant in iodine and balanced in mineral content,
are the saving factor in many of our horses. Allow me to give you an example.
This summer an epidemic of influenza and coughing broke out among two year olds
at the New York tracks. It spread like wildfire through the stables, and all the
old cures and preventives were useless against it. We have checked carefully and
find that none of the horses that were wintered in South Carolina, were
affected. Naturally we spoke of this often, and by so doing attracted the
attention of many people to South Carolina, and the merits of your theories and
We have found that our horses are almost immune to skin diseases, distemper, and
other contagious diseases after they have been wintered in South Carolina and
brought to the tracks where these ailments are taking their toll. You have
observed how quickly we can cure these various ailments in young horses. We
believe that the blood is so cleansed by the action of iodine from your feeds
and water, that all common infections are removed, and the system so toned up
that it is in shape to fight and ward off anything except direct infection
through an open wound. A few years ago a good trainer was one who could bring
his horses to the races well fed and bulging with muscle. But the make-up of
these muscles, and the contents of the bloodstream feeding them, is the
determining factor in having a really fit and ready horse. In appreciation of
the good you have done our horses, and the things we have learned from your
efforts, we trust that you will find time this coming season to again spend
considerable time at the fair grounds, and conduct further experiments on our
In order to learn whether instinct played a part
in leading dairy cows to food rich in iodine, the owner of a mixed herd of 54
cows which I had previously studied built a special feeding station for me at
the end of the lane leading from the barnyard. The station was divided into four
compartments, roofed over to protect them from rain. In one compartment was
placed a feeding supplement,nationally advertised, which contained iodine and
other minerals in inorganic form. The second compartment was supplied with bone
meal, the third compartment with a feeding supplement made of ocean kelp, in
which all the minerals are in organic form. The fourth compartment contained
salt. We stood nearby to observe what happened when the cows passed this feeding
station for the first time.
Each cow sniffed at each compartment. They passed
by without touching the feeding supplement made of inorganic minerals. A few
took some of the bone meal, and a few some of the salt. But what they really
converged on was the kelp, which as has been said contains more iodine than
anything else that grows. As fast as we could fill up the compartment they would
clean it out. This settled the point for us: COWS like iodine and in organic,
which is to say natural, form. Subsequently I offered kelp to two registered
Jersey bulls in the barn. They took it quickly and teased for more.
One of my friends raises hunting dogs as a hobby.
The dogs are Brittany spaniels. When they have been trained to hunt, he sells
Being impressed by the favorable effects of apple cider vinegar on his own
health and body endurance, he asked me if it would be all right to try giving
the vinegar to his dogs. He thought they tired too easily when hunting. We
decided on the following method. When the dogs were not hunting, one
tablespoonful of apple cider vinegar would be added to the ration of each dog
once a day. When they were hunting, there would be a tablespoonful added twice a
day. After following this method for three years at these kennels, the following
conclusions were reached:
If a hunting dog has (1) one tablespoonful of apple cider vinegar added to his
ration once a day during the off-hunting season; (2), one tablespoonful added to
his ration twice a day when used for hunting; (3) one tablespoonful added to his
drinking water while hunting, whenever he is given a drink; (4) one
tablespoonful of undiluted vinegar when the dog is thirsty and no drinking water
The following results were noted:
1. A dog receiving the apple cider vinegar will
not tire easily. The average dog that has not received it is good for three to
four hours of hunting a day. A dog receiving it will hunt eight to ten hours
steady during the day. Apple cider vinegar clearly increases the hunting dog's
2. A dog receiving the apple cider vinegar will be able to point and retrieve
every bird for as many as four hunters hunting at the same time.
3. A dog receiving the vinegar will not show shortness of breath at any time
4. A dog receiving the vinegar will maintain a good appetite and eat every meal
while being used for hunting.
5. A dog receiving the vinegar will not lose weight while hunting.
Having now traced the use of iodine to increase
the speed and endurance of race horses and the endurance of hunting dogs, let us
adapt what we have learned to the health side of the daily life of a business
executive. On rising in the morning he will drink a glass of water while
dressing into which one or two teaspoonfuls of apple cider vinegar has been
mixed. What may he expect to accomplish by doing this?
The knowledge that acids thin body fluids has
been brought over from the days when blood-letting was a common form of
treatment. We have found in the barn that the milk of a normal cow is weakly
acid. When the reaction of the milk changes to alkaline, the milk becomes
soup-thick. This thickness will disappear and the milk will return to its normal
watery character, however, if and when the cow is given four ounces of apple
cider vinegar and four ounces of water by mouth from a bottle, night and
There are other ways of observing this principle
in action but this is sufficient here. The point is, no busy executive wants his
blood to be on the thick side, like soup; he under-stands that it should be
thin, in order to circulate easily throughout the body, making easy work for his
heart as it pumps blood with each beat.
At breakfast this man omits wheat foods, wheat
cereals, white sugar, and citrus fruits and fruit juices because in the majority
of people these foods change the normal acid reac-tion of the urine to alkaline.
The alkalinity is a signal that the blood is thicker than it should be, that it
is not easily circulated and requires more heart effort to pump it. There-fore
this man replaces these unwise foods with rye and corn foods and cereals.
Instead of white sugar he uses honey. In place of citrus foods and citrus juices
he takes the contents of a bottle of fruit sold at the grocery store under the
name Junior Foods. Or, if he chooses, he may take apple, grape, or cranberry
At lunchtime he takes two teaspoonfuls of apple
cider vinegar and two teaspoonfuls of honey in a glass of water. In this way he
obtains acid taken up from the soil by fruit, berries, edible leaves, and roots,
and the energy from the sun which exists in honey. This is a prime pick-up
drink. He may take it before, during, or after lunch. A vinegar made from the
whole crushed apple is best for the purpose.
When a person is organizing his body for a day of
dynamic action, the organization shifts the urine reaction from the normal, or
acid, to the alkaline. It is not advisable, therefore, to eat foods at the
morning meal which will, so to speak, duplicate the shift. For this reason the
wheat foods, white sugar, and citrus fruits and their juices are omitted, so
that at the end of the day he will return home with less mental and physical
At the evening meal he will also take the two
teaspoonfuls of honey and two teaspoonfuls of apple cider vinegar in a glass of
water. He may like to take it before the meal, as a cocktail, or during the
It is beneficial also to start the meal with a
leafy green salad, to get the benefit of the acid from the soil and the energy
from the sun stored up in the leaves. If the day has been one of overwork and
anxiety, turn to fish or other seafood, for that will supply the iodine and
potassium that will calm down the nervous system. Try to have such muscle meats
as beef, lamb, or pork only twice a week, and then on days when you have a light
schedule, because muscle meat organizes your body on a combat basis, which you
do not want from food. Try to bear in mind that the internal organs of an
animal, such as the liver, represent the animal storehouse against the time of
need. It will be well for you to have liver or liverwurst once a week.
Gradually, by following the foregoing plan, you can make changes in your daily
food selection so that the intake will counterbalance your heavy expenditure of
strength and energy.
Supposing you do follow the suggestions outlined
above and yet find that some weeks the pressures of your private and your
business life are causing you to lose the ability to bounce back. Then you
should add a drop of Lugol's solution of iodine to your glass of apple or grape
juice at breakfast, or you may take it in the mixture of apple cider vinegar and
water. The point is that the potassium in the solution blocks off the body
mechanism that organizes for aggressive action, releasing its hold on the body
when opportunity for rest and relaxation arises. The iodine swings into action
the body mechanism which organizes the body for peace and quiet and the building
up and storing of body reserves. When working under pressure, include the
Lugol's solution dose each day until the period of pressure passes. If it should
happen that your body becomes saturated with iodine, you will find that there is
an increase of moisture in the nose. If this occurs, omit the iodine until the
nose is normal.
As you study yourself you will soon learn to tell
when you need iodine. When a night's sleep does not bring you to the beginning
of the new day with the energy you are accustomed to have, you will begin to
think of iodine. If you learn how to use it, it will restore the capacity to
bounce back and sustain your well-being.
on the usefulness of iodine from Dr. Jarvis' book
A young Vermonter not only
learns about the virtues of apple cider vinegar, but he is also taught the
value of Lugol's Solution of Iodine, which was devised in the nineteenth century
by a French physician.
At one time I enlisted the aid of twelve small
children, none of them more than five years old, who were to serve as human
guinea pigs for two years, so that the second year might be compared to the
first year. The object of this study was to learn whether little children
got sick on an alkaline urine or on an acid urine background. In time I learned
that they did indeed become ill on the alkaline reaction and recovered when the
urine was restored to its normal acid reaction.
There were twins in this group of children, and
their mother said to me, " Dr. Jarvis, what am I going to do? One of these
girls is a race horse and the other is a farm horse. I mean that one is nervous,
high strung, and irritable and won't accept discipline. She is always ready to
fight. But the other one has a calm even disposition; she's always so peaceful
and quiet. My problem is that the race horse twin keeps both her calm sister and
me stirred up all the time. It doesn't do any good to spank her because she just
blows up and I have a worse problem on my hands. Tell me, how are we going to
live with this girl?"
"Lets' turn to Vermont folk medicine,"
I said, " and use Lugol's solution of iodine to release the continued
activity of the energy expending mechanism in her body. Any time her motor
shifts into high and she shows the increased speed by becoming a discipline
problem, add a teaspoonful of apple cider vinegar to a glass of water in order
to make the water in the glass acid in reaction. Then add two drops of Lugol's
solution of iodine tot he glass of water, and after the mixture is stirred have
her drink it. Give it to her whenever, she seems to need it to get into lower
gear. It can be done anytime during the day, at meals or between meals."
Two weeks later the mother reported that her race
horse daughter quieted down within two hours after the dosage I had recommended
was given, and with the continued help of the solution she was able to control
the child easily. Sometimes she gave it everyday if it seemed to be needed, or
at longer intervals if there were no outbursts.
Today the twin who was treated is married and in
her own home. With the aid of iodine and vinegar during here growing years her
human motor was brought under control and she developed into a normal girl. By
the time she graduated from high school the tantrums of her childhood were only
a memory. But if she ever becomes high- strung and irritable again, she will
know the remedy.
I recall another child whose mother was a
professor in a college for women before her marriage to a man who was a
university graduate. Their first child, a girl, had an even disposition and was
easy to live with, but their second, another girl, was the kind of race horse
type I have just discussed. The mother came to me with the same complaint as the
harassed mother of the twins, and again I suggested the same folk medicine
remedy of iodine and vinegar. Once more the treatment worked perfectly. The
mother gave me an almost identical report: within two hours her daughter was a
As time passed, this girl too developed into a
normal high school student and was later extremely successful in college, where
she developed her really fine mind and her artistic abilities, as well as the
ability she had acquired to get along with others and make friends.
Two drops of Lugol's solution of iodine works
equally well in an adult. When the stress and strain of daily living create a
load that is difficult to carry, producing a state of anxiety, and when the
day's problems make it difficult to relax and sleep well at night, then
one appreciates the aid that iodine gives.
In an adult two teaspoonfuls of apple cider
vinegar and two of honey are added to a glass of water. The honey is there
because it is a sedative. Then add two drops of Lugol's solution of iodine to
the glass containing the vinegar and- honey mixture, stir it, and sip it during
the meal as you would coffee or tea. Taken apart from the meal it can be
sipped like a cocktail. Soon your motor will have slipped into low gear. Your
problems and their solution will seem less difficult, and the day's load of
responsibility easier to carry. In this age of anxiety the
combination of iodine with vinegar and water will give the harassed
individual increased energy and the endurance necessary to carry the daily load.
You will find that the wear and tear of daily living is considerably reduced.
The same remedy can be applied to cattle, in a
somewhat different way than I have already described in the treatment of
mastitis, although in the example I have in mind the reason fro administering it
was the same. My farmer friend called me one day to inform me that four of his
best cows were sick with acute mastitis of their udders. The veterinarian had
been using the bacteriological approach, employing the sulfa drugs, but without
success. He had just left the barn, said the farmer, telling him that the cows
were going to die. Could I save them?
I told him that attacking bacteria as a solution
to medical problems had not always proved successful, as far as I was concerned,
and I recommended that we try Vermont folk medicine, seeking to release the
energy expending mechanism from its continued activity.
My plan was to change the physiology and
chemistry of each cow's body by giving her morning , noon, and night a
"blood wash" as folk medicine expresses it. We would give each cow by
mouth from a bottle four ounces of apple cider vinegar, four ounces of water,
and a teaspoonful of Lugol's solution, all mixed together.
Before the treatment was applied these cows were
running temperatures as high as 107 degrees. After it was given, the fever began
to drop at once, and by the end of the week all four had recovered from their
sickness. Three of the cows returned to milk production. The fourth did not
produce milk until her next calf was born and a new lactation period was
The folk medicine approach that is, releasing the
energy expanding mechanism from continued activity by giving a "blood
wash"- works if sickness with an accompanying elevation of temperature is
present in a human. Often a single teaspoon of vinegar in a glass of water with
two drops of Lugol's solution of iodine added will cause the body temperature to
drop when the solution is taken morning, noon and evening. Continued use often
brings rapid recovery from sickness.
When you take Lugol's solution you are taking an
excellent catalyst which has the ability to start, and continue at a rapid pace,
physiological and chemical processes within the body that would not otherwise
begin, or if begun, would proceed at a slow pace. Iodine increases the rapidity
of the start, and rate of speed as well. By means of a catalyst the individual
is able to control the internal environment and bring peace to the body.
If a harmful virus or microorganism is among the
factors which cause arthritis Lugol's solution of iodine will be helpful. In the
herd of dairy cows I studied, I decreased the bacteria count of the milk
markedly, as I have shown previously, by adding three drops of iodine to two
ounces of apple cider vinegar, the whole poured over the ration of each cow at
every feeding twice a day.
For pasteurized milk, I might add, a count of
five thousand bacteria in each cubic centimeter of milk is acceptable to the
creamery laboratory. With the addition of vinegar and iodine to the ration the
bacteria count dropped to less that a thousand and did not rise. Often it was
five hundred or less.
