Tundra lichen is edible and has been a part of the diet of various Arctic and Subarctic cultures. However, it should be properly prepared to remove any potential toxins and to make it more palatable.
What Is It?

Why It Can Be Risky
While tundra lichen is generally safe to eat, there are some potential risks to be aware of.
- Some lichens contain toxic compounds that can cause stomach upset or more serious health problems.
- Lichens can absorb pollutants from the air, which can then be ingested when the lichen is eaten.
- Improper preparation can make the lichen difficult to digest.
