Activity in the indications listed has not been adequately demonstrated.
Strawberry leaf can cause allergic reactions in persons with a sensitivity to strawberries.
Since the effectiveness for the claimed applications has not been sufficiently documented, a therapeutic application cannot be recommended. The use of the herb as a filler in tea mixtures is acceptable. In fact, the use of strawberry leaf for teas or tea-like products is to be considered a food additive.
