Dual extraction is a process used to extract the beneficial compounds from Lion's Mane mushrooms (Hericium erinaceus) using both water and alcohol. Dual extraction involves soaking the lion's mane mushrooms in hot water to extract water-soluble compounds such as polysaccharides and beta-glucans. Then, the same mushrooms are soaked in alcohol to extract the alcohol-soluble compounds such as erinacines and hericenones. The water extract and alcohol extract are then combined to create a "dual extract" that contains a broader range of beneficial compounds than either extract alone.
