About Chaga

Chaga is one of the herbs many Americans ask about, so Herbalist Kareem has included it in this guide for your education. Below you will find a short, plain-language overview of how this herb has traditionally been used, how people commonly enjoy it, and the safety points everyone should know before adding it to a daily routine.

Traditional uses

Chaga is a mushroom that grows on birch trees in cold climates. It has traditionally been brewed as a tea in Russia and Northern Europe to support vitality and the body’s natural defenses.*

Traditional use describes how people and cultures have worked with a plant over many generations. It is a valuable part of herbal knowledge, but it is not the same as medical proof, and every body responds differently.

How it is commonly enjoyed

Usually simmered as chunks or powder to make a dark, earthy tea. Start with small amounts, follow the directions on the product label, and pay attention to how your body responds. Herbs work best as part of a balanced lifestyle that includes whole foods, water, movement, and rest.

Safety notes

Important caution: This is an herb that calls for extra care. Please read the safety notes below carefully and speak with a qualified healthcare provider before use.

Chaga is very high in oxalates, and heavy use has been linked to kidney problems. Avoid if you have kidney concerns. It may affect blood sugar and blood clotting medications. Use only in moderation.

As with any herb: avoid it if you have a known allergy to the plant or its plant family, ask your doctor or pharmacist before use if you take prescription medications, and talk with your provider before use if you are pregnant, breastfeeding, or giving herbs to a child. Stop use and seek medical care if you notice any unusual reaction.

What researchers are studying

Scientists continue to study Chaga. One example from the published literature is a scientific review:

Zhong XH, Ren K, Lu SJ, et al. (2009). Progress of research on Inonotus obliquus. Chinese journal of integrative medicine.

Research like this is often early, small, or done in the lab, and it does not prove that Chaga treats or prevents any condition. We share it so you can see that this herb is a subject of ongoing scientific interest.
