Chaga, scientifically known as Inonotus obliquus, is a mushroom commonly utilized as a dietary supplement with purported benefits on immune function and cancer prevention, although these claims are primarily supported by in vitro and animal studies. Rich in polyphenols, melanin, triterpenoids, and polysaccharides, particularly well-researched for their potential health effects, Chaga has demonstrated anticancer properties by inhibiting cancer cell replication and enhancing immune system activity in both lab-based and animal research. Moreover, it has shown promise in inhibiting viral infections and reducing oxidative stress and inflammation. Despite these potential benefits, safety data for Chaga is limited, with a notable concern being its high oxalate content, a compound linked to kidney stones. While anecdotal evidence suggests relative safety, two case reports have associated long-term Chaga consumption with oxalate-induced kidney disease, underscoring the need for cautious use and further research.
