What are the possible side effects of Maitake mushroom (Grifola frondosa)?
Maitake has not been studied thoroughly in humans, and its effects are not well known. Because it has been used historically as a food, it is thought that low doses may be safe. Studies in animals suggest that it may lower blood pressure. However, no information about these effects is reported for humans. Individuals who take blood pressure medications should use caution. Animal studies report that maitake may lower blood sugar levels. Caution is advised in patients with diabetes or hypoglycemia, and in those taking drugs, herbs, or supplements that affect blood sugar. Blood glucose levels may need to be monitored by a healthcare professional, and medication adjustments may be necessary.
