All tinctures are created with a double extraction process of the fruit body of each mushroom. The Reishi mushroom is particularly popular in Eastern medicine. Reishi is known to help reduce stress, strengthen the immune system, and have benefits to the heart and liver. Recommended use is one dropper full (1oz.) twice daily. Taken regularly with hot tea before bed may help in a more restful night’s sleep and ease anxiety and depression in some cases.
