Both fruiting bodies and mycelia are rich in active, health promoting substances. Tests of substances extracted from this mushroom carried out on animals and in vitro have given good results. They can be used in the treatment of cancer, hepatic disorders, Alzheimer’s and Parkinson’s diseases, wound healing. They improve cognitive abilities, support the nervous and immune systems. Promising results have been reported in clinical trials and case reports about the human treatment (e.g., recovery from schizophrenia, an improvement of the quality of sleep, alleviation of the menopause symptoms). 
Normal essential metabolic processes or external sources such as exposure to pollution, alcohol, tobacco smoke, heavy metals, pesticides, certain drugs and radiation cause the formation of free radicals in the organisms. Antioxidants inhibit free radical reactions and cellular damage in living organism. Although human body is protected against free radical damage by antioxidant defense and repair systems, the balance between the antioxidant defenses and the production of free radicals may be disrupted. If there is an imbalance between the antioxidant and oxidant in the human body, called oxidative stress, may cause many diseases such as rheumatoid arthritis, arteriosclerosis, cirrhosis and cancer may occur. Hericum americanum has been shown to have high antioxidant components and the ability to reduce oxidative damages from the above influential free radicals that the population is exposed to daily.
