Dr. Niwa is a well-known Japanese physician and researcher who caused a sensation worldwide with his findings on the effects of free radicals. Over 30 years of research have shown that most diseases and the aging process are caused by free radicals. Dr. Niwa runs his own hospital in Japan as well as 9 clinics. There, skin and immune diseases as well as cancer are treated with predominantly natural medicines.

Evidence That Naturopathic Therapy Including Cordyceps Sinensis Prolongs Survival of Patients With Hepatocellular Carcinoma

One of his natural medicaments
Cordyceps Sinensis (Brand names are Tohzan, NK-3, Tohchu-jo, and Tohchu Extract).
The active ingredient of Cordyceps Sinensis is a substance called cordycepin. The cordycepin I use is not chemically produced. I use naturally grown Cordyceps Sinensis, which goes through the process of heating, brewing and lipophilisation. Cordyceps Sinensis is a parasitic fungus that infects insects. It has long been used in traditional Chinese medicine. The active ingredient of Cordyceps Sinensis has been the subject of research around the world since 1950. The key factor seems to be the hydroxyl group (OH) attached to the third carbon (C) of the ribose in the structure of adenosine, a key component of DNA (Diagram 8).
It was discovered, over forty years ago, that cordycepin has an effect on cancer in both humans and animals. This has also been proven by in vitro analysis. By comparing the structures of cordycepin and adenosine (Diagram 8), one notices that the C3 of cordycepin has a hydrogen (H) attached to it instead of an OH.
Otherwise, the two structures are the same. When Cordyceps Sinensis is taken into the body, the DNA of dividing cancer cells will accept the cordycepin and incorporate it, as the structures are very similar. However, because of the difference between the OH and the H, the cordycepin will interfere with the cancer cells' DNA and stop the cancer cells multiplying.
Other anticancer effects of Cordyceps Sinensis have been reported on different tumour cell lines and rodent systems, including inhibition of polyadenylation, stimulation of adenosine A3 receptors and the induction of apoptosis (the active and functional death of cells).
Cordyceps Sinensis is the most outstanding medicine with the strongest anticancer effect out of all the medicines used in Niwa Therapy (including for liver cancer patients).
It is also effective against violent viral diseases such as AIDS and SARS. Also, for genetically abnormal diseases (cystic psoriasis, Darie's disease), Western medicine has only harsh chemicals that can cause malformed children, but the author's processed Cordiceps sinensis is effective.
