I've never heard of this mushroom before. I became curious, read literature, I decided. In Asia they use it as food. In medicine, as a means of possessing antioxidant properties and capable of reducing blood sugar levels. As well as the substances of this fungus protect from the death of brain cells, inhibit the formation of beta-amyloid plaques in the brain, have a positive effect on memory, learning ability, reduce damage to free radicals. I took 30 drops in the morning on an empty stomach in a swallow of boiled water, almost 2 months. The effect was still taking - improving short-term memory, yes. It would be good to repeat, and at least 3-4 months
