What it is
Two different parts of the plant serve two different purposes. A 2024 review of 6 trials found nettle root significantly improves urinary symptoms in men with enlarged prostate. The leaf form has separate evidence for seasonal allergies, where it may help reduce sneezing and itching. Generally well tolerated with a good safety profile.
