During the Second World War, the United States dropped two atomic bombs in Japan, causing the atomic bomb to explode within three months, but only a few shiitake mushrooms grew on several pieces of wood.
This phenomenon has aroused the interest of Japanese scientists. Finally, in 1963, it was found that there is a polysaccharide in the mushroom that can resist radiation and enhance the immunity of plants and animals.
In 1966, Japan industrialized the result and tried it on a large number of cancer patients. It received good results and was called the "atomic bomb explosion" in the medical world.
Since then, polysaccharides from edible and medicinal bacteria have attracted extensive attention in the fields of biology, medicine, pharmacy, and food science.
The value of mushroom polysaccharides contained in Grifola frondosa in many mushroom species should not be underestimated. The National Cancer Institute of the United States has confirmed in 1992 that the extract of Grifola frondosa is resistant to HIV.
At the same time, through the synergistic effect of medicinal drugs, Grifola frondosa can significantly improve the therapeutic effect and reduce the toxic and side effects of radiotherapy and chemotherapy. Its medicinal value is immeasurable, and it is known as "the king of immunity, anti-cancer wonderful".
The mushroom polysaccharide content of Grifola frondosa is higher than the nutritional value of Ganoderma lucidum and Cordyceps, ranking first in all kinds of food.
