Major ingredients for anti-cancer capacity have been known as protein-bound polysaccharides or polysaccharides and basic proteins, and such therapy produces the most ideal treatment effect when accompanied by the existing anti-cancer drugs. (Mushroom Science/1998/authors/Seong Jae-mo, Yu Yeong-bok, Cha Ding-ryeol) Recently, the research team of prof. Jeong Gyeong-su at the College of Pharmacy, Chungnam National University reported some results of a clinical study to confirm the anti-cancer effects of Sang-hwang mushroom studied and reported around the world.

The medical circles have shown great interests in Snag-hwang mushroom for its surprising anti-cancer effect but it was not known to general public because of its rarity. The active ingredient of Sang-hwang mushroom was extracted and tested for its directing killing of cancer cells and the result confirmed almost 100% of its effects, which confirmed the study result of 96.7% of cancer cell killing effects reported in a clinical experiment performed in Japan.
