Lion’s mane (Hericium erinaceus) is another type of medicinal mushroom. Long used in traditional Chinese medicine, lion’s mane is widely available in supplement form. Scientific research shows that lion’s mane contains a number of health-promoting substances, including antioxidants and beta-glucan. Proponents claim that lion’s mane can help with a variety of health problems, including:
- Alzheimer’s disease
- High cholesterol
- Parkinson’s disease
Lion’s mane may benefit older adults with mild cognitive impairment, according to a small study published in Phytotherapy Research in 2009. For the study, researchers assigned 30 older adults with mild cognitive impairment to take either lion’s mane extract or a placebo every day for 16 weeks. In cognitive tests given at weeks eight, 12, and 16 of the study, members of the lion’s mane group showed significantly greater improvements compared to members of the placebo group. In a more recent study (published in Biomedical Research in 2011), scientists examined the effects of lion’s mane on brain function in mice. Results revealed that lion’s mane helped protect against memory problems caused by the buildup of amyloid beta (a substance that forms the brain plaques associated with Alzheimer’s disease). Studies have also shown a possible neuro-protective effect against ischemic stroke..
Lion’s mane may help alleviate depression and anxiety, suggests a small study published in Biomedical Research in 2010. For the study, 30 menopausal women consumed cookies containing either lion’s mane or a placebo every day for four weeks. Analyzing study findings, researchers observed that members of the lion’s mane group were less irritable and anxious and had less difficulty concentrating than members of the placebo group.
Preliminary research suggests that lion’s mane shows promise in protection against cancer. For instance, in a 2011 study published in Food & Function, tests on human cells revealed that lion’s mane may help knock out leukemia cells.
In addition, a 2011 study published in the Journal of Agricultural and Food Chemistry found that lion’s mane extract helped reduce the size of cancerous colon tumors in mice. The study’s findings suggest that lion’s mane may help fight off colon cancer, in part by increasing activity in certain cells involved in the immune response. Another study found that the extract might help reduce the spread of colon cancer cells to the lungs.
