Treating
the Undesirable Effects of Radiation and Chemotherapy with Chinese
Medicine

As Chinese medicine becomes more available
as a system accessible to the general public, more and more people
suffering with cancer are coming to utilize the rejuvenating effects
of the Chinese herbal, acumoxa, dietary and qigong therapies to
prolong life and aid in their recovery from this poweful illness.
Although Chinese medicine has evolved primary treatments for the
treatment of cancer, in this country there are still legal problems
with this approach, and most western cancer patients at this time
will choose to combine biomedical treatment with alternative therapies.
Although a limited number of successes have been recorded with biomedical
treatments such as surgery, chemotherapy, and radiation, time and
research have shown limitations to success, and the search for better
treatments and cures continues. Many forms of cancer, although proven
to be unresponsive to chemotherapy, continue to be treated by this
method. Often chemotherapy, surgery and radiation will cause damage
to healthy as well as to diseased tissues, and weaken the immune
system. This is where Chinese medicine can be very helpful.
The concept of "side effects"
is not recognized as such in Chinese medicine. The toxic effects
of certain medicinals is recognized according to degree, and if
it is necessary to use a 'toxic' substance medicinally, it will
be prepared in a special manner or combined with other medicinals
to reduce or eliminate toxicity if possible. For example, fu zi/rx.
aconiti is considered toxic, but it has a very strong medicinal
power to mobilize and rescue yang Qi to the spleen and kidney. It
is usually combined in Chinese herbal prescriptions with sheng jiang/rx.
zingiberis and gan cao/rx. glycyrhhizae to neutralize the toxic
effect. Sometimes the principle of du yao gong xie/use toxin to
attack Pathogenic Evil is used clinically; we can look at the modern
use of chemotherapy according to this principle, if not in the degree
of its clinical application in biomedicine. In Chinese medicine,
it is considered unthinkable to damage the host or the Zheng Qi/Correct
Qi in any clinical intervention.
Chinese herbal medicine treats the
use of most chemotherapeutic agents and radiation as "Heat
Toxins" that damage the Yin and Qi. However, such chemotherapy
drugs as cisplatin lower sperm counts (weaken jing/essence), cause
stomatitis (heart fire), diarrhea (damage to spleen Qi), hearing
loss, and leukopenia. In Chinese medical analysis, cisplatin will
kill fast-growing cells, such as mucosa and intestinal lining as
well as cancer cells, weaken Kidney Jing and Yang, weaken Spleen
Yang, aggravate heart fire all at the same time. This shows the
extreme effects of toxic substances on the body, which can cause
damage to Yin, Yang, Qi and Blood, and cause extreme hot and cold
reactions concurrently. In Chinese cancer hospitals, the use of
chemotherapy and radiation are often combined with the use of herbal
medicine to protect the body/mind from damage as much as possible.
Dosages of chemotherapeutic drugs also tends to be lower than in
western countries. In my opinion, it makes clinical sense to use
the least toxic dose possible of anti- cancer drugs, radiation or
surgery given concurrently with herbal prescriptions to protect
the body and zheng Qi/correct Qi from damage. This may help relieve
discomfort and suffering to the patient, and also minimize the suppression
of immune function. This is a realistic expectation, considering
the more lengthy goal of using Chinese herbs, diet, qigong and acumoxatherapy
more extensively in cancer therapy in the west.. Presently, a practitioner
of Chinese medicine may be asked to do the job of a "mop-up
crew", cleaning up the side-effects of excessive drug treatment.
In filling this demand, however, we can do much good. At the same
time, this effort should not compromise us in seeing the shortcomings
of this type of therapy.
In Chinese medicine, the optimum functioning
of spleen/stomach Qi is considered critical to life. According to
the classics, when spleen/stomach Qi is damaged or in decline, a
patient's life and health are in danger. Chemotherapy drugs often
will damage the lining of the stomach and intestines, leading to
symptoms of nausea, vomiting, loss of appetite, and a burning sensation.
The toxins produced by cancer cells will often weaken the Spleen/Stomach
Qi as well. Chinese adjunctive cancer therapy includes supporting
the Spleen/Stomach Qi and its function of digestion and assimilation.
Formulas such as shen ling bai zhu tang/Ginseng, Poria and Atractylodes
Decoction and iu jun zi tang/Six Gentlemen Decoction are ideal for
this purpose, containing herbs to strengthen the Spleen/Stomach
such as Ren Shen/Ginseng and Bai Zhu/Atractylodes, as well as herbs
to Clear Phlegm and Damp such as Ban Xia/Pinellia and Chen Pi/Citrus
Peel. These formulas could be either supplemented or replaced by
Yin tonics in cases of extreme Heat and/or Dryness of the Stomach,
which would be aggravated by this formula if used alone. However,
many types of cancer show accumulation of Phlegm and Damp, and Six
Gentlemen Decoction will be efficacious in these cases.
Supplementing the Yin is also very
important for many patients receiving conventional cancer treatment.
The Fire and Toxin created by both radiation and most chemotherapeutic
drugs, wastes the Yin, leading to dry mouth, thirst, mouth sores,
constipation and scanty, dark urination. The pulse may be rapid
and thready, the tongue red, dry and cracked. The Shen may also
be disturbed by the heat buildup in the chest. Aggressive treatment
over time can often disturb the Kidney and Heart/Shao Yin aspect,
leading to insomnia, restlessness, disorientation, sterility, lower
back pain, and palpatation. Formulas such as liu wei di huang wan/Rehmannia
Six Flavor Pill, tian wang bu xin dan/Celestial Emperor's Heart
Supplementing Pill, and zhi bai di huang wan/Anemerrhena, Phellodendron
and Rehmannia Six Flavor Pill are very useful in these cases. When
there are signs of Lung and Stomach Yin Vacuity, including stomach
pain and burning, dry mouth, dry cough, dry skin, a peeled red tongue
with scanty yellow coat, and a thin, thready, rapid pulse, sha shen
mai dong yin/Glehnia and Ophiopogonis Cool Decoction is a choice
formula. Finally, yi guan jian/Linking Decoction is very useful
for liver and kidney yin vacuity with Liver Qi Depression, a common
pattern encountered with cancer patients.
It is important to support the Zheng
Qi/Correct Qi to defend the body against the various forms of cancer,
which can only thrive in a disordered body and mind. The weakening
of Zheng Qi/Correct Qi by stress, environmental toxins, dietary
and lifestyle indiscretions can take its toll, allowing cancer to
proliferate, and even pass on a constitutional predisposition to
the disease. The medicinal mushrooms are all very effective for
strenghtening and repairing body/mind intelligence and immune function.
Both xiang gu/lentinus (shitake) and ling zhi/ganorderma (reishi)
mushrooms have been shown to have strong anti-tumor effects in recent
studies, and are powerful strengthening agents to the Zheng Qi .
In the Shen Nung P'en Tsao/Divine Husbandman's Materia Medica, ling
zhi is considered to be a "superior" herb, with strong
supplementing properties to all of the Yin viscera. In recent Chinese
studies, it was also shown to be valuable in reducing the damaging
effects to Blood and Yin from chemotherapy. Cordyceps/dong chong
xia cao is another medicinal fungi from the Chinese pharmacoepia
used to aid in recovery from a severe illness, and especially strengthens
immune function.
Huang Qi/astragalus is one of Chinese
medicine's supreme Qi supplementers, and has been shown to be the
most effective herb to restore damaged immune systems. It is presently
used routinely in oncology departments of Chinese hospitals. In
a joint study between a Texas pharmaceutical company and a hospital
in Beijing, it was found that astragalus was most effective when
combined with nu zhen zi/ligustrum, another yin supplementing herb
for the Liver and Kidney, which has been shown in modern studies
to have a strong immune strengthening effect. Astragalus is a major
component with ren shen/ginseng (also shown to have anti-tumor and
immune-enhancement effects) in bu zhong yi Qi tang/Supplement the
Middle and Augment the Qi Decoction, a major Yang and Qi supplementing
formula.
Many of the chemotherapy anti-cancer
agents were discovered in the plant world. Today, massive searches
and clinical trials are sponsored in the rain forests and wilderness
regions around the world for new cancer cures. At the present time,
clinical trials and research are being sponsored by pharmaceutical
companies on Chinese herbs that have anti-cancer properties. Vincristine
and vinblastine, taken from madadasgar periwinkle, were discovered
by the Lilly drug company during clinical trials done on so-called
"folk treatments" used in different cultures for cancer
treatment. However, it may be that the vast herbal pharmacopia may
be best utilized in the traditional method of polypharmacy, where
many ingredients are combined to reduce and eliminate side effects
while balancing all the systems of the body.
To conclude, Chinese herbal medicine
is the therapy of choice in treating the side-effects of Western
oncological treatments, and is proven in its effectiveness. However,
we should not ignore the tremendous potential of Chinese medicine
in the treatment of cancer as a major therapy in its own right.
