Lion’s Mane mushroom or Hericium erinaceus is a type of edible fungus that has been used in Chinese and Japanese medicine for many years. The health benefits of Lion’s Mane mushroom have started gaining a lot interest in the recent years especially as it concerns cognitive function, inflammation and metabolic disease.
This interest has led to many researches on the possible health benefits of Lion’s Mane mushroom which have been found effective in different animal models. In this list of studies, we have included 50 potential health benefits associated with Lion’s Mane mushroom including effects on cognition; inflammation; oxidative stress and metabolic disorders as well skin and liver health, exercise performance.
Although these studies present early evidence of the health benefits associated with Lion’s Mane mushrooms, further research is required to establish their effectiveness and safety in human beings particularly under clinical conditions.
