People take stinging nettle to try to treat health problems, including:

Some research shows that stinging nettle root may be helpful in treating this problem. Experts are not sure which components in the plant may have an effect on BPH. More research is needed to show that the treatment is indeed effective.
Allergies. Stinging nettle leaf may be useful in reducing the symptoms of hay fever by acting as an anti-inflammatory.

People have also used stinging nettle as a diuretic -- a treatment that causes the body to shed more water in the urine. Research has found this effect from stinging nettle in rats.
Optimal doses of stinging nettle have not been set for any condition. Quality and active ingredients in supplements may vary widely from maker to maker. This makes it hard to set a standard dose.
