Are there any other types of Reishi?
Of the six varieties of Reishi that have undergone extensive study – red, black, purple, blue, yellow and white – only red and black have been shown to offer significant health benefits. Only Red Reishi, however, can boast the greatest impacts on immune system, organ function and overall health. Black Reishi (Ganoderma Sinensis, in Latin), typically found in Chinese herbal stores, contains fewer polysaccharides than Red Reishi and is widely considered to be a less effective supplement.
