The claimed efficacy has not been documented.
The plant contains protoanemonin. It is known that severe irritations with itching and pustule formation (ranunculus dermatitis) occur on skin and mucous membranes when preparations of fresh protoanemonin-containing plants or protoanemonin are applied. Upon internal use, higher dosages may lead to irritations of the kidneys and urinary tract.
Application is contraindicated during pregnancy.
Protoanemonin is destroyed upon drying.
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.
