As of the early 21 century, much has been written about Grifola Frondosa’s apparently magical healing qualities. Studies have shown the powerful effects of Grifola Frondosa on the immune system in laboratory animals.
Asian medicine claims that Grifola Frondosa boosts the human immune system and limits or reverses tumor growth. It is also said to enhance the benefits of chemotherapy and reduce some of the side effects of anti-cancer drugs, such as hair loss, pain, and nausea.3
The active elements in the Grifola Frondosa mushroom are Beta-Glucan Polysaccharides, known to lower blood sugar and cholesterol. Beta-Glucan Polysaccharides appear to slow the growth of some cancer cells in some cell cultures in mice.
Grifola Frondosa is also understood to stimulate the immune system. As shown in lab studies, Beta-Glucan Polysaccharides activate certain cells and proteins, such as t-cells, natural killer cells (white blood cells), and interleukin-1 and -2, that attack cancer, including macrophages.
