Upon internal use, higher dosages may lead to irritations of the kidneys and urinary tract.

Protoanemonin is destroyed upon drying.

Evaluation

Since the effectiveness for the claimed uses has not been documented, and considering the risks, a therapeutic application of protoanemonin-containing preparations cannot be justified.
