Chaga

Chaga, also known as Inonotus obliquus, is a mushroom commonly used as a dietary supplement. There are claims that it has beneficial effects on immune function and cancer prevention. However, these claims are limited to in vitro (studies done in petri dishes or test tubes) and animal studies, as there is only one study in humans.[1]

Our evidence-based analysis on chaga features 24 unique references to scientific papers.
