Harvesting Guidelines

Chaga should always be harvested with deep respect and awareness. Only harvest from living birch trees and leave at least one-third of the conk intact to allow the fungus to regenerate. Avoid harvesting from dead trees, as chaga loses its potency after the host tree dies. Sustainable wild harvesting or the use of cultivated chaga from ethical sources is encouraged, particularly as demand increases. Some practitioners prefer to forage chaga during winter when its active compounds are most concentrated.

Chaga is a slow-growing fungal medicine revered for centuries across the cold northern forests of the world. Found primarily on birch trees in regions like Siberia, northern China, Canada, Alaska, and parts of the northern United States and Europe, chaga begins its life as a spore that infiltrates the heartwood of its host. Over the course of one to two decades, it forms a dense, blackened mass that bursts through the bark of the birch. This hardened growth, called a conk, resembles burnt charcoal on the outside but holds a rich, rust-colored interior packed with bioactive compounds. While chaga offers extraordinary healing potential, it ultimately kills its host tree, which makes sustainable and respectful harvesting essential.

In Siberian folk medicine, chaga has been used for generations to brew a dark, earthy tea believed to restore strength, build resilience, and promote long life. It is considered a powerful adaptogen, a substance that helps the body respond more effectively to stress. Russian herbal traditions have long used chaga to treat gastrointestinal issues, inflammatory diseases, infections, and even cancer. In Finland and the Baltic states, chaga was a traditional substitute for coffee and is still consumed daily as a general tonic and immune booster.

Among many traditional medicine practitioners, chaga is considered a spiritual ally, connecting the individual to the forest and to the mycelial intelligence of the Earth. Some Indigenous peoples refer to chaga as a "gift of the North" and use it in ceremonies and wellness practices to promote spiritual protection, grounded awareness, and energetic clarity. Chaga is viewed as a guardian fungus that accumulates the protective energies of its environment, particularly from birch trees, which themselves are associated with purification and new beginnings.

Modern research supports many of chaga’s traditional uses. It contains high levels of polysaccharides that modulate immune response, as well as betulinic acid, derived from the birch itself, which exhibits antiviral, anti-inflammatory, and anticancer properties.

A study published in Mycobiology found that chaga extract significantly reduced oxidative stress in animal models, affirming its strong antioxidant capacity. Another study in Biomedicine & Pharmacotherapy highlighted chaga’s ability to reduce blood sugar levels and improve insulin sensitivity, showing promise for type 2 diabetes. Chaga’s sterol compounds may also help lower LDL cholesterol and support cardiovascular health, though more clinical trials in humans are needed.
