Agaricus mushroom is a fungus. It originated in Brazil, but is now grown in China, Japan, and Brazil for sale. A solution containing chemicals that are taken from the plant (extract) is used as medicine.
Agaricus mushroom is used for cancer, type 2 diabetes, high cholesterol, “hardening of the arteries” (arteriosclerosis), ongoing liver disease, bloodstream disorders, and digestive problems. Other uses include prevention of heart disease, weakened bones (osteoporosis), and stomach ulcers. It is also used to boost the immune system and for physical and emotional stress.
In Japan, extracts of the agaricus mushroom are approved as a food additive.
