  • Cancer Prevention and Management

    Many herbs or natural supplements are promoted for cancer prevention and treatment. Although these natural remedies do show efficacy in laboratory experiments, the practical implications of such findings are unclear. It is because cancer-related research is quite challenging. Studies show that Reishi Mushroom may improve quality of life or may even improve response to anticancer therapy. Therefore, specialists suggest that Reishi Mushroom can be used in conjunction with traditional drug therapy. Studies show that Reishi Mushroom may help breast cancer survivors to alleviate fatigue and improve their quality of life.

It may also have a mild anti-diabetic effect. Although clinical studies only show mild changes in biomarkers of heart health, it is quite probable that Reishi may help in other ways that are not currently proven or fully understood.6

  • Protects the Liver from Toxins

    Studies indicate that Reishi Mushroom has an ability to protect the liver from toxins. In experimental studies, Reishi Mushroom could protect liver cells from α-Amanitin, a kind of toxin found in certain mushrooms. Researchers think that this may be due to the antioxidant capacity of Reishi Mushroom and other phytocompounds it contains.7
