Reishi (Ganoderma lucidum) has been highly prized for thousands of years in China as the "Elixir of Immortality" and "Spirit Plant". As a "superior" tonic it was believed to balance and support your body systems, including heart, lung, liver, nerve and brain function. Reishi in the "Super Reishi" is log grown free of synthetic pesticides or fertilizers. It contains both hot-water and alcohol concentrated extracts in order to achieve the maximum range of beneficial constituents, such as active B-glucans and terpenes. It is also enhanced with immune boosting Maitake D-fractions.
