Agaricus blazei Murrill (AbM) (Subrufescens) is popularly known as 'Cogumelo do Sol' in Brazil, or 'Himematsutake' in Japan.
According to tradition, it fights physical and emotional stress, stimulates the immune system, improves the quality of life in diabetics, reduces cholesterol, prevents osteoporosis and peptic ulcers, treats circulatory and digestive problems and fights cancer.
According to the conclusions of https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7285126/
This review on scientific in vivo findings with three of the most well-known medicinal mushrooms, AbM, HE and GF, shows that they possess valuable antitumor, anti-inflammatory and antiallergic properties. These should be investigated more thoroughly with quality-controlled and standardized mushroom extracts, or fractions thereof, in randomized clinical studies powered to show putative therapeutic effects. In this way, medicinal Basidomycota could become significant supplementary drugs in Western medicine.
