Like shiitake and maitake, chaga is a medicinal mushroom often used to rev up the immune system and fend off illness. Many proponents even suggest that taking chaga supplements--or drinking chaga tea--can increase the body's defense against cancer.
Although there is currently a lack of scientific support for the claim that chaga can help prevent cancer, some preliminary research shows that chaga can slow up the growth of cancer cells. What's more, a number of studies indicate that chaga can combat oxidative stress (a destructive biological process thought to be linked to the development of cancer).
To protect against cancer, it's crucial to avoid smoking, follow a balanced diet rich in antioxidant-packed vegetables and fruits, exercise regularly, and keep your weight in check. Some studies have found that people who drink tea and maintain optimal levels of vitamin D may be less likely to develop certain types of cancer. Read the article: Chaga - What You Need to Know.
