<p><strong>PROGESTERONE INFORMATION</strong></p>
<p>
Sixty years ago, progesterone was found to be the main hormone produced by the ovaries. Since it was
necessary for fertility and for maintaining a healthy pregnancy, it was called the "pro-gestational
hormone," and its name sometimes leads people to think that it isn't needed when you don't want to get
pregnant. In fact, it is the most protective hormone the body produces, and the large amounts that are
produced during pregnancy result from the developing baby's need for protection from the stressful
environment. Normally, the brain contains a very high concentration of progesterone, reflecting its
protective function for that most important organ. The thymus gland, the key organ of our immune system, is
also profoundly dependent of progesterone.
</p>
<p>
In experiments, progesterone was found to be the basic hormone of adaptation and of resistance to stress.
The adrenal glands use it to produce their antistress hormones, and when there is enough progesterone, they
don't have to produce the potentially harmful cortisol. In a progesterone deficiency, we produce too much
cortisol, and excessive cortisol causes osteoporosis, aging of the skin, damage to brain cells, and the
accumulation of fat, especially on the back and abdomen.
</p>
<p>
Experiments have shown that progesterone relieves anxiety, improves memory, protects brain cells, and even
prevents epileptic seizures. It promotes respiration, and has been used to correct emphysema. In the
circulatory system, it prevents bulging veins by increasing the tone of blood vessels, and improves the
efficiency of the heart. It reverses many of the signs of aging in the skin, and promotes healthy bone
growth. It can relieve many types of arthritis, and helps a variety of immunological problems.
</p>
<p>
If progesterone is taken dissolved in vitamin E, it is absorbed very efficiently, and distributed quickly to
all of the tissues. If a woman has ovaries, progesterone helps them to regulate themselves and their hormone
production. It helps to restore normal functioning of the thyroid and other glands. If her ovaries have been
removed, progesterone should be taken consistently to replace the lost supply. A progesterone deficiency has
often been associated with increased susceptibility to cancer, and progesterone has been used to treat some
types of cancer.
</p>
<p>
It is important to emphasize that progesterone is not just the hormone of pregnancy. To use it only "to
protect the uterus" would be like telling a man he doesn't need testosterone if he doesn't plan to father
children, except that progesterone is of far greater and more basic physiological significance than
testosterone. While men do naturally produce progesterone, and can sometimes benefit from using it, it is
not a male hormone. Some people get that impression, because some physicians recommend combining estrogen
with either testosterone or progesterone, to protect against some of estrogen's side effects, but
progesterone is the body's natural complement to estrogen. Used alone, progesterone often makes it
unnecessary to use estrogen for hot flashes or insomnia, or other symptoms of menopause.
</p>
<p>
When dissolved in vitamin E, progesterone begins entering the blood stream almost as soon as it contacts any
membrane, such as the lips, tongue, gums, or palate, but when it is swallowed, it continues to be absorbed
as part of the digestive process. When taken with food, its absorption occurs at the same rate as the
digestion and absorption of the food.

<strong>PROGESTERONE SUPPLEMENTATION </strong>
</p>
<p>
SYMPTOMATIC: For tendonitis, bursitis, arthritis, sunburn, etc., progesterone in vitamin E can be applied
locally after a little olive oil has been put on the skin to make it easier to spread the progesterone
solution. For migraines, it has been taken orally just as the symptoms begin.
</p>
<p>
FOR PMS: The normal pattern of progesterone secretion during the month is for the ovaries to produce a large
amount in the 2<sup>nd</sup> two weeks of the menstrual cycle, (i.e., day 14 through day 28) beginning at
ovulation and ending around the beginning of menstruation, and then to produce little for the following two
weeks. An average person produces about 30 milligrams daily during the 2<sup>nd</sup> two weeks. The
solution I have used contains approximately 3 or 4 milligrams of progesterone per small drop. Three to four
drops, or about 10 to 15 milligrams of progesterone, is often enough to bring the progesterone level up to
normal. That amount can be taken days 14 through 28 of the menstrual cycle; this amount may be repeated once
or twice during the day as needed to alleviate symptoms. Since an essential mechanism of progesterone's
action involves its opposition to estrogen, smaller amounts are effective when estrogen production is low,
and if estrogen is extremely high, even large supplements of progesterone will have no clear effect; in that
case, it is essential to regulate estrogen metabolism, by improving the diet, correcting a thyroid
deficiency, etc. (Unsaturated fat is antithyroid and synergizes with estrogen.)
</p>
<p>
PERIMENOPAUSAL: The symptoms and body changes leading up to menopause are associated with decreasing
production of progesterone, at a time when estrogen may be at a lifetime high. The cyclic use of
progesterone, two weeks on, two weeks off, will often keep the normal menstrual cycle going. Three to our
drops, providing ten or twelve milligrams of progesterone, is typical for a day, but some women prefer to
repeat that amount. Progesterone is always more effective when the diet contains adequate protein, and when
thee isn't an excessive amount of unsaturated fat in the diet..
</p>
<p>
POSTMENOPAUSAL: Some women continue the cyclic use of progesterone ater menopause, because the pituitary
gland and brain may continue to cycle long after menstruation has stopped, and progesterone is an important
regulator of pituitary and brain function. The cycling pituitary affects the adrenal glands and other
organs, and progesterone tends to protect against the unopposed actions of prolactin, cortisol, and adrenal
androgenic hormones. Progesterone's effects on the pituitary apparently contribute to its protective effect
against osteoporosis, hypertension, hirsutism, etc. But some women prefer to use progesterone without
interruption after the menopause, for its protective antistress effects. Slender people usually find that
two or three drops are enough, but this amount may be repeated once or twice as needed to relieve symptoms.
Adequate protein in the diet and good thyroid function help the body to produce its own progesterone; even
if the ovaries have been removed, the adrenal glands and brain continue to produce progesterone.

<strong>DOSAGE OF PROGESTERONE</strong>
<p>
Since progesterone has none of the harmful side effects of other hormones (except for alteration of the
menstrual cycle if it is taken at the wrong time of month), the basic procedure should be to use it in
sufficient quantity to make the symptoms disappear, and to time its use so that menstrual cycles are not
disrupted. This normally means using it only between ovulation and menstruation unless symptoms are
sufficiently serious that a missed period is not important. The basic idea of giving enough to stop the
symptoms can be refined by some information on a few of the factors that condition the need for
progesterone.
</p>
<p>
If a person has an enlarged thyroid gland, progesterone promotes secretion and unloading of the stored
"colloid," and can bring on a temporary hyperthyroid state. This is a corrective process, and in itself
isn't harmful. A thyroid supplement should be used to shrink the goiter before progesterone is given. Normal
amounts of progesterone facilitate thyroid secretion, while a deficiency, with unopposed estrogen, causes
the thyroid to enlarge. The production of euphoria has been mentioned as a side effect, but I think euphoria
is simply an indication of a good physiological state. (The history of official medical attitudes toward
euphoria is a subject that deserves more attention.) Very large doses that are given in vitamin E solution,
allowing complete absorption, can reach the level that is sometimes achieved late in pregnancy, producing
both euphoria and a degree of anesthesis. To avoid unexpected anesthesia, the correct dose should be
determined by taking about 10 mg. at a time allowing it to spread into the membranes of the mouth, and
repeating the dose after 10 minutes until the symptoms are controlled.
</p>
<p>
An excessive estrogen/progesterone ratio is more generally involved in producing or aggravating symptoms
than either a simple excess of estrogen or a deficiency of progesterone, but even this ratio is conditioned
by other factors, including age, diet, other steroids, thyroid, and other hormones. The relative estrogen
excess seems to act by producing tissue hypoxia (as reported in my dissertation, University of Oregon,
1972), and this is the result of changes induced by estrogen in alveolar diffusion, peripheral vascular
changes, and intracellular oxygen wastage.
</p>
<p>
Hypoxia in turn produces edema (as can be observed in the cornea when it is deprived of oxygen, as by a
contact lens) and hypoglycemia (e.g., diminished ATP acts like insulin), because glycolysis must increase
greatly for even a small deficiency of oxygen. Elevated blood lactic acid is one sign of tissue hypoxia.
Edema, hypoglycemia, and lactic academia can also be produced by other "respiratory" defects, including
hypothyroidism, in which the tissue does not use enough oxygen. In hypoxia, the skin will be bluer (in thin
places, such as around the eyes), than when low oxygen consumption is the main problem. Low thyroid is one
cause of excess estrogen, and when high estrogen is combined with low thyroid, the skin looks relatively
bloodless.
</p>
<p>
Symptoms in cycling women are most common around ovulation and in the premenstrual week, when the
estrogen/progesterone ratio is normally highest. At puberty, in the early twenties and in the late thirties
and menopause are the ages when the ratio is most often disturbed--and these are also the ages when thyroid
disorders are commonest in women.
</p>
<p>
The individual who suffers from one aspect of the progesterone (and/or thyroid) deficiency will tend to
develop other problems at different times. With cyclic depressions or migraine headaches at age 22, there
will possibly be breast disease later, and often there will be problems with pregnancy. These people with a
history of sever symptoms are the ones most likely to have severe problems around menopause. Prenatal
exposure to poorly balanced hormones seems to predispose the child to later hormone problems.
</p>
<p>
Excess stress (which can block progesterone synthesis and elevate estrogen) may bring on symptoms in someone
who never had them. Spending a summer in Alaska, with an unusually long day, may relieve the symptoms of a
chronic sufferer. Dark cloudy winters in England or the Pacific Northwest are powerful stressors, and cause
lower production of progesterone in women, and testosterone in men. Toxins can produce similar symptoms, as
can nutritional deficiencies. A very common cause of an estrogen excess is a dietary protein deficiency--the
liver simply cannot detoxify estrogen when it is under-nourished.
</p>
<p>
With a diet high in protein (e.g., at least 70-100 grams per day, including eggs) and vitamin A (not
carotene), I have found that the dose of progesterone can be reduced each month. Using thyroid will usually
reduce the amount of progesterone needed. Occasionally, a woman won't feel any effect even from 100 mg. of
progesterone; I think this indicates that they need to use thyroid and diet, to normalize their estrogen,
prolactin, and cortisol.
</p>
<p>
Progesterone stimulates the ovaries and adrenals to produce progesterone, and it also activates the thyroid,
so one dose can sometimes have prolonged effects. It shouldn't be necessary to keep using progesterone
indefinitely, unless the ovaries have been removed. In slender post-menopausal women, 10 mg. per day is
usually enough to prevent progesterone deficiency symptoms.
</p>
<p>
In a 10% solution of progesterone in vitamin E, one drop contains about three milligrams of progesterone.
Normally, the body produces 10 to 20 milligrams per day. A dose of 3 or 4 drops usually brings the blood
levels up to the normal range, but this dose can be repeated several times during the day if it is needed to
control symptoms.
</p>
<p>
For general purposes, it is most economical and effective to take progesterone dissolved in vitamin E
orally, for example taking a few drops on the lips and tongue, or rubbing it into the gums. (It is good for
the general health of the gums.) These membranes are very thin, and the progesterone quickly enters the
blood. When it is swallowed, the vitamin E allows it to be absorbed through the walls of the stomach and
intestine, and it can be assimilated along with food, in the chylomicrons, permitting it to circulate in the
blood to all of the organs before being processed by the liver. These droplets are smaller than red blood
cells, and some physicians seem to forget that red blood cells pass freely through the liver.
</p>
<p>
For the topical treatment of sun damaged skin, or acne, wrinkles, etc. the oil can be applied directly to
the affected area.
