Sapp is a concoction of birch-tree sap, apple juice, and “adaptogenic, immune-boosting chaga.” Extracts of the chaga mushroom have not been assessed in human trials, interact with several medications, and may cause kidney damage in frequent users, so “immune-boosting chaga” would not be how I’d describe this ingredient.

It’s “frequently bought together” with Maple Water, a bottled drink thankfully only containing maple sap.
