Protecting Yourself from the Health Hazards of Xenoestrogens
by Steven H. Horne, RH (AHG)
Estrogens are great hormones. After all, they are the hormones that make women feminine, and as a male, I happen to
be quite attracted to femininity. But, there are some estrogenic
compounds in the environment that are not so great. They are
called xenoestrogens and they are causing serious health problems
in both men and women.
Before I can discuss the health risk of xenoestrogens, it is
probably a good idea to provide a little background information
about estrogens in general. I use estrogen in the plural, because
there really is no single compound called “estrogen.” The human
body makes three different estrogen hormones—estrase,
estrone and estriol.
Plants also produce estrogen-like compounds called phytoestrogens.
These compounds are not chemically identical to
the estrogens produced by the body, but they still attach to
estrogen receptor sites and influence reproductive health.
And finally there are xenoestrogens, the topic of this article.
Xenoestrogens are environmental pollutants that have
estrogen-like activity. These compounds are a primary cause of
reproductive health problems in both women and men because
they attach to and over-stimulate estrogen receptor sites. This
causes changes in estrogen-sensitive tissues like the breasts, uterus
and prostate. Xenoestrogens stimulate abnormal changes in
these tissues, causing problems like cysts in the breasts, uterine
fibroids, prostate enlargement and cancer.
Do xenoestrogens affect men as well?
A small amount of estrogen is necessary in men to prevent
bone loss and for sex drive. The fact that men have only a small
amount of estrogen is also the reason hormone replacement is
much safer for men. As a man ages, his testosterone declines
allowing his body to accumulate fat particularly around the
belly. Belly fat contains an enzyme called aromatase that converts
testosterone to estrogen. The rise in estrogen and decrease
in testosterone make the men feel bad.
Excess estrogen combined with DHT, the stronger form of
testosterone, promotes BPH, otherwise known as a swollen prostate.
Excess estrogen increases the rise of prostate cancer through
the same process that occurs in a woman’s beast. It increases
the potential for conversion of estrogen to 16-alpha hydroxyl
Xenoestrogens contribute to the death of testicular tissue in
men and boys, depression caused by testosterone suppression,
premature aging, infertility and obesity. The link between xenoestrogens
and obesity can readily be seen by the high rates of
obesity in areas where there is high exposure to xenoestrogens
(farms in the Midwest and the industrial deep South). So, men
should also avoid xenoestrogens and take steps to balance their
Just like women have more than one form of estrogen,
men have more hormones than testosterone that contribute to
our masculinity. These hormones, which include testosterone,
androstenedione (andro), androstenediol, dihydrotestosterone
(DHT) and DHEA-M, are collectively known as androgens. The
ratio of androgens and estrogens in the body is important.
Androgens like testosterone are not just important for a
man’s sex drive. They are also important for men’s overall health.
Testosterone helps a man put on muscle and burn fat. It elevates
a man’s mood to keep him from becoming depressed. It protects
him from heart disease and cancer. Testosterone also makes a
man more creative and imaginative. So, the bottom line is having
a high level of testosterone is good for a man.
Most of the testosterone in a man’s body is bound. This
means that it’s not immediately available for use. Only a small
percentage, about 2-3%, is free testosterone. As men age, levels
of free testosterone decline. This is responsible for a shift in
middle age men called andropause. Men naturally become a
little less aggressive and a little more sensitive. However, if men
start making, or are exposed to, too many estrogens and/or have
too little free testosterone, this shifts the androgen/estrogen balance
and causes numerous health problems like prostate swelling,
infertility, weight gain, etc.
So, how can men increase their testosterone levels for a better
Well, for starters, looking at attractive women stimulates testosterone
production. That’s probably part of the reason married
men tend to live longer than single men! So, guys don’t feel guilty
that it makes you feel good to see a pretty girl, it’s normal.
Exercise also helps free testosterone for use, particularly exercising
the legs with resistance training. Eating organically raised,
grass fed beef also enhances testosterone in men. Actually, beef in
general enhances testosterone, but commercially raised beef just
isn’t as healthy as grass-fed beef.
There are also testosterone-enhancing herbs and supplements
men might consider. According to Steven Buhner the
pollen of pine trees is one of the strongest androgenic herbs
that increases levels of free testosterone in the blood. It is used
in Chinese medicine as a rejuvenating tonic, but is not a widely
used remedy in the United States.
Testosterone-enhancing herbs that most men would have
easy access to include, Korean ginseng (Panax ginseng), American
ginseng (P. quinquefolia), eleuthero root (Eleutherococcus senticosus),
tienchi ginseng (P. notoginseng) and puncture vine (Tribulus
terrestris). These herbs can be useful tonics for men to take as we
get older because they help stimulate the production of androgens
and slow the effects of aging in men.
There are also some useful supplements for enhancing
androgens. These include: pregnenolone, DHEA-M, zinc and
pantothenic acid. Saw palmetto and nettle root (found in Men’s
Formula) help inhibit androgens from converting into estrogens,
which can also help male hormone balance.
Pesticides and Miscarriage
My introduction to the problem of xenoestrogens came
when my last wife almost had a miscarriage after being exposed
to pesticides. We were living in a rented home and the landlord
sprayed the fruit trees in the yard. He asked my wife to come out
so he could show her the damage that borers had been causing
to the trunks of the trees. This exposed her to the fumes from
the just-sprayed trees.
That night she started cramping and bleeding. She took lots
of capsicum and bayberry to control the bleeding, vitamin E
and false unicorn to inhibit contractions, and we both prayed.
Fortunately, the bleeding stopped the next day.
When we relayed the incident to our midwife, she told us
she was impressed because every mother she had ever known
that had been exposed to that particular pesticide had miscarried.
At the time, I did not know that this particular pesticide
was an endocrine disrupter, an estrogen mimic, but we soon
learned that it is very common for women to miscarry after this
pesticide has been sprayed in their neighborhood.
So, if these poisons can have that dramatic of an effect on
a woman’s pregnancy, imagine what regular low doses of them
are doing to the reproductive systems of both men and women.
One can readily see why reproductive health problems are on
the increase worldwide.
Other Sources of Xenoestrogens
Pesticides, however, are only one source of estrogen pollution
in our modern world. Another is commercial dairy, meat
and eggs. There are two reasons for this. One is that dairy and
egg farmers often feed estrogenic chemicals to milk cows and
chickens because it increases production of milk and eggs. This
alone makes commercial dairy, eggs and meat major sources
However, there is another reason animal foods are major
sources of xenoestrogens. Pesticides tend to be fat soluble, so
they accumulate in the fat of animals. When an animal is eaten
by another animal pesticides concentrate in that animal’s fat,
too. So, the higher up the food chain you go, the more pesticides
tend to accumulate in fat. This is why pesticides began
to damage the reproduction in birds of prey. So eating the fat
from commercial (non organic) dairy foods and meat gives you a double dose
of estrogen pollution.
Plastics are another source of xenoestrogens, particularly soft
plastics. So, if you drink whole milk from commercial dairies
in soft plastic jugs, you get a triple dose of estrogen pollution.
Oh, and think about all that bottled water we are drinking.
If those plastic containers get hot, they leach chemicals, like
xenoestrogens, into the water. It’s bad to put hot food into
plastic containers for the same reason or to microwave food
in plastic containers. (Of course, it’s a bad idea to microwave
You can greatly enhance your reproductive health by purchasing
organically grown food wherever possible (or a least
avoiding foods from animals that have been fed hormones and
washing produce to remove sprays). Avoid using pesticides in
your home or on your property, too. Finally, wherever possible,
use glass instead of plastic containers.
Detoxification from Xenoestrogens
Obviously, one cannot completely avoid chemicals like
xenoestrogens in one’s life, so it’s also important to do some
detoxification to help the body get rid of the xenoestrogens
(and other chemicals) it is exposed to. The liver breaks down
all excess hormones for elimination, so supporting the liver is
very helpful. A good formula to use for general detoxification,
including helping the liver get rid of xenoestrogens, is All Cell
Detox. Another option is Enviro-Detox.
Cruciferous vegetables contain compounds
that help the enzyme pathways in the liver that
break down excess estrogens. Eating broccoli,
cauliflower, cabbage and other vegetables from
the mustard family is a great way to support
your liver’s detoxification ability. One of the
compounds in these vegetables is Indole 3
Carbinol, which is available as a supplement.
Indole 3 Carbinol is very helpful for getting rid
of excess estrogen and can be helpful for any condition involving
excess estrogen stimulation, including breast and reproductive
cancers, uterine fibroids and fibrocystic breasts.
Foods rich in phytoestrogens can also help protect the
body from estrogen pollution. Phytoestrogens tend to be very
weak in their effects, but they tie-up estrogen receptor sites so
the stronger xenoestrogens can’t attach to them. Soy products
are widely promoted for their phytoestrogenic effects, but too
much soy is not good for you, so don’t over do it with the soy
products. Instead, consume a wide variety of foods rich in phytoestrogens,
such as beans and peas, dark green leafy vegetables
and whole grains.
The lignans in flax seed are also phytoestrogenic compounds.
So, flax seeds and flax seed oil that contains lignans are also
sources of beneficial phytoestrogens. A number of herbs are
also good sources of phytoestrogens, including black cohosh,
licorice root and hops.
Although I have not used it in my own
clinical practice, Breast Assured is essentially a phytoestrogen
supplement which can be taken regularly by women who are
concerned about reducing exposure to xenoestrogens. It will
help prevent breast cancer, breast lumps, uterine fibroids and
other problems caused by excessive estrogen stimulation.
Increasing progesterone levels can also be helpful, as progesterone
and estrogen are antagonists that compete for the
same receptor sites. My first choice in helping to balance these
hormones would be vitex or chaste tree berry, which works
on the pituitary to help regulate female hormone balance. It
is a slow-acting herb and works best when taken regularly for
three to six months. It is found in the Wild Yam and Chaste
For women who experience heavy bleeding due to excessive
estrogen, there are three remedies that can help balance these
hormones. One is false unicorn, which has a progesterone-like
effect. It has been used to prevent miscarriage (as in the story
I told at the beginning of the article) and can also be used to
combat heavy bleeding and estrogen-based conditions.
Sarsaparilla can also be used. It has a more testosterone-like
effect. Yes, women also make testosterone, just like men make
estrogen, and increasing testosterone can also help
balance out female hormones.
Menstrual-Reg is a formula I helped to design.
It is for heavy bleeding and contains herbs
to both balance hormones and control bleeding.
Like chaste tree, it is going to work best when
taken regularly for a period of several months.
Adding one capsule of yarrow per two capsules
of Menstrual-Reg will improve its effectiveness
against heavy bleeding, especially in the case of
Progesterone creams would be my last choice in balancing out
excess estrogen. I realize that many women find them helpful,
but they are not correcting the diet or the internal balance of
hormones. In other words, they are treating the effect without
dealing with the cause. Also, you can get too much progesterone
as well as too much estrogen.
You can get your hormones tested, and creams can be
compounded which contain the right amounts of natural
estrogen, progesterone and/or testosterone to properly balance
your system. However, I would try dietary changes and herbal
supplements first and use this route only if you have serious
problems that need immediate attention or have failed to find
solutions through diet and herbs.
As a parting comment, as I was in the process of writing
this article, I was invited to speak to a breast cancer survivor
group. Because all but one of the women in the group (the
one who invited me to speak) had gone the medical route in
their cancer treatment, I chose to speak about the problem of
xenoestrogens. It was interesting that nobody knew anything
about xenoestrogens at the beginning of my lecture, but by the
end of my lecture they all realized that avoiding xenoestrogens
would be helpful for both preventing and treating breast cancer.

Dr. Peter Eckhart, MD:
1. Do not heat food or water with plastic in the microwave. Do not drink hot liquids in foam styrofoam cups or receptacles.
2. Change your laundry detergent because it cannot be fully washed from the clothes and can be absorbed through the skin. Do NOT use dryer sheets or fabric softener.
3. Do not use anything on the skin with parabens or phenoxyethanol in them. This includes shampoo, soap, makeup, hand lotion, body lotion, and toothpaste. Oral substances are 90% filtered by the liver. Skin-absorbed substances are 100% absorbed by the body, thus, a skin dose is 10 times an oral dose.
4. Avoid coffee. Avoid decaf coffee. No caffeine. No tea. No colas. Caffeine increases estradiol levels by 70%!
5. No sunflower oil, no safflower oil, no cottonseed oil, no canola oil. (Guess that leaves olive oil and Grapeseed Oil).
6. Avoid shampoos that are “rich in hormones” and have estrogen added to them.
7. Avoid estrogenic herbs especially TOPICALLY such as sage and rosemary.
8. Many sunscreens are estrogenic. Use a hat and long sleeved shirt.
9. Use cosmetics with minerals or grapefruit seed extract as a preservative.
Dr. Elizabeth Smith, MD:
* Use glass or ceramics whenever possible to store food and water. Heat up your food using a glass or ceramic bowl covered with dish. When plastic is heated, it diffuses very rapidly into food.
* Use a simple detergent with less chemicals.
* Simple Soap is a safe choice for shampoo and a body soap.
* Use natural pest control not pesticides.
* Avoid Synthetic Chemicals – Healthy Living in a Toxic World by Cynthia Fincher PhD. is a good place to start.
* Don’t use herbicides; use a cup of salt in a gallon of vinegar.
* Buy hormone free meats to eat.
* Buy “Organic” produce, produce grown without pesticides, herbicides or synthetic fertilizer or hormones.
* Use Condoms without spermicide for Birth control instead of Birth Control Pills. Use Natural Progesterone instead of HRT.
* In general, the hormones taken orally are first pass metabolized by the liver 80%-90%. However, when these hormones are applied to the skin, the hormones are directly absorbed by the body. Thus, any skin dose is 10 times that of an oral dose. The vast majority of skin lotions and creams use the parabens as a preservative. Avoid them at all costs. Instead apply a vegetable oil right after a shower to hydrate the skin and lock in the moisture.
