Question: Do reishi mushroom supplements boost the immune system, or have other benefits?
Answer: Reishi mushroom (Ganoderma lucidum), also referred to as lingzhi, is an edible mushroom traditionally used in Chinese medicine for a wide range of purported health benefits, such as increasing vitality and strengthening the heart. In the U.S., supplements containing reishi are most commonly promoted for another use -- "strengthening" the immune system, as well as for lowering blood sugar, improving cardiovascular function, protecting from liver damage and reducing cancerous tumors. However, there are only limited clinical studies of reishi and concerns about product quality (ConsumerLab will be testing mushroom supplements in 2018). Sign in to see the full answer >>
