Lion's mane mushroom (Hericium erinaceus) is an edible mushroom with potential health benefits. 
 
Some of the purported benefits include:
 
Cognitive function: Lion's mane contains compounds called hericenones and erinacines, which may stimulate the production of nerve growth factor (NGF). This may improve cognitive function, memory, and focus
Anxiety and depression: Studies suggest that lion's mane may have anti-inflammatory and antioxidant properties that can reduce anxiety and depression symptoms.
Immune system support: Lion's mane may boost the immune system by stimulating the production of white blood cells.
Gastrointestinal health: Lion's mane may help protect the stomach lining from ulcers and reduce inflammation in the digestive tract
Heart health: Some studies indicate that lion's mane may lower cholesterol levels and improve blood flow, potentially reducing the risk of heart disease
Wound healing: Lion's mane may promote wound healing by stimulating the production of collagen
