Nettle's purported anti-inflammatory effects have been repeatedly confirmed by modern research over the past ten years. It is particularly effective in treating allergic rhinitis, relieving nearly all the symptoms of itchy, watery eyes, sneezing and runny nose. It also has performed better than the prescription drug furosemide in reducing blood pressure, increasing urine output as a diuretic and increasing salt excretion. It also seems to be effective in reducing pain and producing a sedative effect. It is important to keep in mind that the medicinal effects of the leaf and root of the nettle are markedly different. Nettle root, for instance, shows exceptional efficacy in treating prostate complaints in men. Nettle leaf has some of the same effects, but not to the same extent. The leaf, on the other hand, shows some promise in boosting immune system function and is an effective treatment for many skin conditions. One final use should be noted and that is nettle leaf has been used as a hair and scalp treatment for centuries, and again, those uses are being supported by research as well. Nettle leaf extract seems to promote hair regrowth and thicken hair, as well as reducing dandruff and scalp conditions when used as a rinse. Precautions Because of its diuretic and hypotensive actions, nettle leaf may lower blood pressure. If you are taking diuretics or other drugs meant to lower blood pressure, consult your doctor before using nettle leaf. Its long term, extended use is not recommended.
