5. Nettle extract powder benefits

a. Antioxidant resistance to diseases

Adding antioxidants to your diet can help you fight free radicals, which can damage your cells and play a role in heart disease and cancer. According to the Mayo Clinic, antioxidants are molecules that protect the body from free radicals. Free radicals come from daily activities, such as the body breaking down food and harmful lifestyle activities, such as smoking.

A small study published in the Avicenna Journal of Phytomedicine from November to December 2016 studied the effect of nettle as an antioxidant on type 2 diabetes and found that Contains antioxidants. The study concluded that taking nettle extract can reduce the risk of heart disease and other complications in people with diabetes.

Another study, published in the French journal Comptes Rendus Chimie in September 2016, studied the effects of antioxidants in nettle extract on cosmetics. The researchers concluded that the antioxidants in nettle extract have anti-aging potential by inhibiting certain enzyme activities, such as elastase and collagenase.

b. Treatment of benign prostatic hyperplasia (BPH)

As men get older, they will develop benign prostatic hyperplasia (BPH), also known as prostate enlargement. According to the Mayo Clinic, this common condition can cause problems such as difficulty urinating, frequent or urgent need to urinate, and may cause bladder, urethral or kidney problems.

It is still unclear what causes the prostate to enlarge, and the size of the prostate does not explain the severity of male symptoms. Family history and lifestyle habits, such as exercise, may cause this to happen.

A research review published in the African Journal of Traditional, Complementary and Alternative Medicines in February 2016 stated that nettle root extract may help treat these symptoms.

The researchers observed four double-blind controlled studies involving more than 1,100 participants and concluded that nettle root is a safe and effective treatment for low urinary tract symptoms associated with prostate hyperplasia. According to the Hershey Company of Pennsylvania, USA, nettle root is a commonly used medicine for the treatment of BPH in Europe.

c. Treat symptoms of hay fever

According to the American College of Allergy, Asthma and Immunology, more than 40 million Americans suffer from allergic rhinitis, commonly known as hay fever. Despite this nickname, allergies are not just caused by hay; outdoor and indoor allergens, including grass, trees, pet hair, and mold, can cause runny nose, itchy eyes, sneezing, and stuffy nose. Hay fever may also be related to irritability, sleep problems, fatigue, and lack of concentration.

A small study published in the winter of 2017 in the Iranian Journal of Pharmaceutical Research pointed out that nettle root extract may improve the symptoms of allergic rhinitis. However, there was not enough difference between participants taking nettle root extract and those taking placebo, so researchers need to conduct more research to determine its effectiveness.

Before taking nettle supplements for hay fever, consult an allergy specialist to see if this is good for you.

d. Improve blood pressure

Nettles may help improve a person’s blood pressure, especially those who suffer from high blood pressure. An animal study published in the Journal of Translational Medicine in September 2016 showed that nettle extract has a hypotensive effect, but human studies are still needed. This supplement can act as a calcium channel blocker, reducing contractility and relaxing your heart.

Another animal study published in the journal Phytomedicine in July 2018 also found that nettle extract supplementation is beneficial for high blood pressure. This study determined the positive effect of nettle’s antioxidant capacity on oxidative stress in rats.

However, according to Beaufort Memorial Hospital, stinging nettle can lower blood pressure, and it can make drugs that treat high blood pressure more effective.

e. Relieve symptoms of arthritis

Arthritis is not just a disease, but a way of referring to joint pain or joint disease. According to the Arthritis Foundation, arthritis is very common-there are more than 100 different types of arthritis in the United States, affecting 50 million adults and 300,000 children. Common symptoms include joint swelling, stiffness, pain and reduced range of motion, which can lead to chronic pain and difficulty in daily activities (such as walking).

A study published in Phytomedicine in January 2014 concluded that nettle root extract may help relieve symptoms of arthritis. Researchers observed how nettle root extracts, as well as extracts from stems, leaves, and flowers affect inflammation, and found that extracts from roots, stems, and leaves exhibit powerful anti-inflammatory effects.

They pointed out that for inflammatory diseases such as arthritis, these extracts may be more effective than traditional treatments (such as tinctures).
