Chaga Folklore

The word ‘Chaga‘ is derived from the old Russian word for mushroom, from the language of the indigenous people living near the Ural Mountains. In the 12th century, Tsar Vladimir Monomakh, also known as the Grand Prince of Kievan Rus, was widely known as a Chaga enthusiast. Apparently, this ancient Russian leader used these mushrooms to cure his lip cancer.


Skin and Mucous Membranes

Chaga has traditionally been used to help address issues with epithelial tissue (mostly the skin and the lining of the digestive and respiratory tracts) and this continues into modern times. It seems to impart much of its activity due to a maximum antioxidant support against daily free radical damage,[1,2] thereby protecting cellular DNA.


Intestinal And Respiratory Health

Chaga has been shown in animal studies to decrease intestinal inflammation and balance the local immune response,[3] as well as offer a positive impact on the intestinal microbiome.[4] Chaga has also been shown to help reduce an overactive immune response in the lungs.[5,6]


Host Defense Chaga

Host Defense’s advanced culturing techniques of the mycelium preserve a wide array of full-spectrum constituents and allows for nutrients to be provided in a fully bio-available form. Sustainably grown without adversely affecting the native mycoflora.
