Cluster of edible Maitake mushrooms (Grifola frondosa) in a paper sack resting on a rustic wooden table in western Washington, USA. Maitake D-fraction® is an extract of this large mushroom native to the mountains of northeastern Japan. The maitake mushroom is eaten as a food, and maitake-D fraction is marketed as a dietary supplement in the United States and Japan. The substance in the maitake mushroom is thought to be active in humans and is called beta-glucan. Promoters claim that maitake mushroom extract boosts the immune system and limits or reverses tumor growth. It is also said to enhance the benefits of chemotherapy and lessen some side effects of anti-cancer drugs, such as hair loss, pain, and nausea.
