What is the difference between red and black Reishi/Ling zhi?
Red Reishi is Ganoderma lucidum, and Black Reishi is Ganoderma sinensis. They are different species, so their properties may be slightly different. Consult a Chinese Materia Medica. However, research conducted by the Hong Kong Baptist University TCM department, indicates that red Ling zhi/reishi contains more spores than the black Ling zhi/reishi, thus making them more potent for immune enhancement.
