Functional or Medicinal Mushrooms are a class of non-psychoactive fungi that are cultivated and harvested for their potential health-promoting properties. These mushrooms possess a vast array of biologically active compounds that impart unique adaptogenic, nootropic and antioxidant capabilities, among others. Functional mushrooms have garnered increasing attention due to their nutrient density and bioactive constituents, which may offer protection against chronic issues and support overall well-being. Notably, these mushrooms contain polysaccharides, beta-glucans and other immunomodulatory compounds that can modulate the immune system and enhance its function. The proposed benefits of functional mushrooms are not only relevant from a nutritional standpoint but are also intriguing from a scientific viewpoint, revealing an exciting avenue for future research in the field of mycology.
