We have suffered the scarcity of the socialist years, and surfeited on the excesses of the consumerist age. Perhaps it is time to draw a balance, and arrive at the ethical and intelligent approach of thrift. More>>
Many herbs (including astragalus, dong quai, echinacea, and Asian ginseng)
supposedly "boost" the immune system and so shore up the body
against future or existing cancer. Extremely small studies suggest that
shiitake or maitake mushrooms, mistletoe, extracts of the Venus flytrap,
and various botanical therapies used in traditional Chinese medicine may
help treat certain forms of cancer. But until better evidence is in, we
cannot completely rely on them. Ginger, and maybe some other herbs, may
help relieve nausea that often accompanies conventional cancer therapies.
Mistletoe
(Viscum album L.) is a semi-parasitic plant that lives with several
tree species, including oak, pine, fir, elm and apple, and has been used
since ancient times to treat a variety of human ailments. Extracts of
mistletoe have been shown to kill cancer cells in the laboratory and to
stimulate the immune system.
Only the European species of mistletoe is used in the treatment of cancer.
Mistletoe preparations are used to stimulate the immune system and to
kill cancer cells. It has been reported to reduce tumor size and improve
the quality of life and survival of some cancer patients. Three components
of mistletoe (lectins, alkaloids and viscotoxins) may be responsible for
its biologic effects.
A typical treatment course lasts several months to years with subcutaneous
injections given early in the morning 3-7 times per week. The doses are
gradually increased and adjusted depending on the patient's general condition,
sex, age, and type of cancer.
Mistletoe is typically given by subcutaneous injection, ideally near the
site of the tumor while avoiding irradiated areas. It is sometimes injected
directly into the tumor particularly on the liver, esophagus and cervix.
Mixed results have been obtained in animal studies that have investigated
the ability of mistletoe extracts to slow tumor growth. There is no evidence
from well-designed clinical trials that mistletoe or any of its components
are effective treatments for human cancer.
Saw
Palmetto (Serenoa repens) is a low growing palm native to the
southeastern United States, particularly Florida. The part of the plant
used for medicinal purposes is the berries, which are harvested, dried,
and ground for preparation as a tea or in capsules. It is often prescribed
for the treatment of benign prostatic hyperplasia (BPH), or as an anti-inflammatory.
Interestingly, saw palmetto berries do not seem to reduce the size of
an enlarged prostate, but rather relieve the symptoms associated with
BPH such as frequent urination. Saw palmetto is not believed to interfere
with accurate measuring of prostate specific antigen, or PSA (a marker
for prostate cancer).
All of the studies show that Saw Palmetto extract is effective for both
subjective and objective measurements of prostatic enlargement . Other
studies show that Saw Palmetto extract selectively antagonizes 52% of
the dihydrotestosterone receptors in the prostate, thus inhibiting the
hormone from binding to them, and therefore minimizing its stimulation
of cell growth.
Essiac (a mixture of herbs) is actually a combination of several herbs.
It originally contained burdock root, the inner bark of slippery elm,
sheep sorrel, and Turkish rhubarb. More recent combinations have added
watercress, blessed thistle, red clover and kelp (to aid with effectiveness
and improve taste). These herbs are combined to form a tea, which is then
administered orally in an effort to promote health, strengthen the immune
system, improve appetite, relieve pain, improve overall quality of life,
and reduce the size of tumors.
While
Essiac-type formulas are available at a reasonable cost in many health
food stores, the brew is potentially even less expensive, since it is
derived from weeds found in many backyards.
Essiac's use is growing in both the U.S. and Canada, where it is legal,
but only for terminal cancer
patients.
In the early 1900's, Harry Hoxsey developed a herbal formula that he believed
was effective for the treatment of cancer. It consisted of two remedies,
one to be used externally, the other internally. The external mixture
is said to be selectively destructive of cancerous tissue and consists
of a red paste containing antimony trisulfide, zinc chloride, and bloodroot,
and a yellow powder containing arsenic sulfide, sulfur, and talc. The
internal mixture is a liquid containing licorice, red clover, burdock
root, stillingia root, barberry, cascara, prickly ash bark, buckthorn
bark, and potassium iodide. This mixture is considered to be cathartic
and immune boosting. Hoxsey felt that his therapy normalized and balanced
the body's chemistry makeup, allowing it to essentially create a self-healing
environment in which the immune system is strengthened and tumors are
caused to die. The treatment is available in Tijuana, Mexico. (Contact

The dose of the therapy varies depending on the specific needs of each
patient and whether the cancer is internal
or on the skin.
The
preparation is used either directly on the skin or drunk as a tonic. Patients
are encouraged to avoid pork, vinegar, tomatoes, carbonated drinks and alcohol,
and to use immune stimulants, yeast tablets, vitamin C, calcium, laxatives, and
antiseptic washes, as well as adopt a positive mental outlook while taking the
Hoxsey treatment.
Birch
(Betula alba) was
tapped by the American Indians for its sap, for a beverage and as a syrup. Oil
of wintergreen can be distilled from its inner bark and twigs. Traditionally,
it has been used for treatment of diarrhea, dysentery, cholera, and all diseases
of the alimentary tract. It is said to be a good "blood cleanser." It
has been an approved medication in Russia since 1834.
Externally applied, it is a traditional treatment for "eczema and
cutaneous diseases," according to Alma R. Hutchens' A Handbook of
Native American Herbs. So it should be little surprise that the white
birch may be a source of potent chemicals useful in the fight against
melanoma and other kinds of cancer.
In March, 1995, John Pezzuto of the University of Illinois, Chicago reported
that one of these compounds, called betulinic acid, was able to kill human
melanoma cells transplanted into mice. Dr. Pezzuto extracted betulin from
birches and converted this into betulinic acid. According to the scientist,
betulinic acid "worked better than the drug most commonly used in
people to treat melanoma." Unlike conventional chemotherapy, this
compound caused no apparent side effects and, for obvious reasons, is
potentially very inexpensive.
Aloe vera has long been known for it medicinal properties. Traditionally,
as well as today, aloe gel has been used to sooth dry or damaged skin, treat minor
cuts and burns, and the latex has been used for constipation. The root is sometimes
used for colic. In some parts of the world, such as India, aloe is used to treat
intestinal infections. Aloe may be able to help stimulate the immune system, and
may also have an anti-inflammatory effect. Studies are currently underway to explore
these effects.
In just the last few years attention has focused on aloe for a different
reason. Aloe has been found to contain a substance called acemannan. This
has shown potential as a treatment for AIDS and cancer. In a number of
studies, acemannan has had both immunostimulatory and directly antiviral
properties. It is non-toxic even when injected at high doses, causing
"no significant signs of intoxication and no deaths."
