6 Benefits of Nettle (Plus Side Effects)
Nettle has been a staple in herbal medicine since ancient times.
The ancient Egyptians used nettle to treat arthritis and lower back pain, while Roman troops used it for warmth.
Nettle leaves have hair-like structures that sting and also cause itching, redness and swelling.
Once processed into a supplement, dried, freeze-dried, or cooked, nettle can be safely consumed. Research has linked nettles to a number of potential health benefits.
Here are 6 evidence-based benefits of nettle.
Nettle leaves and root provide a wide variety of nutrients, including:
– Витамини: Витамини А, С и К, както и няколко витамини от група В
– Минерали: Калций, желязо, магнезий, фосфор, калий и натрий
– Мазнини: линолова киселина, линоленова киселина, палмитинова киселина, стеаринова киселина и олеинова киселина
– Аминокиселини: Всички основни аминокиселини
– Полифеноли: кемпферол, кверцетин, кофеинова киселина, кумарини и други флавоноиди
– Пигменти: Бета-каротин, лутеин, лутеоксантин и други каротеноиди
What's more, many of these nutrients act as antioxidants in your body.
Antioxidants are molecules that help protect your cells from free radical damage. Damage caused by free radicals is linked to aging as well as cancer and other harmful diseases.
Research shows that nettle extract can increase blood antioxidant levels.
Summary: Копривата предлага разнообразие от витамини, минерали, мастни киселини, аминокиселини, полифеноли и пигменти – много от които действат и като антиоксиданти във вашето тяло.
Inflammation is your body's way of healing itself and fighting infections.
However, chronic inflammation can cause significant harm.
Nettle hides various compounds that can reduce inflammation.
In animal and test-tube studies, nettle reduced levels of multiple inflammatory hormones by interfering with their production.
In human studies, applying nettle cream or consuming nettle products appears to relieve inflammatory conditions such as arthritis.
For example, in one study of 27 people, applying nettle cream to arthritic areas significantly reduced pain compared to a placebo treatment.
In another study, taking a supplement containing nettle extract significantly reduced arthritis pain. In addition, the participants felt that they could reduce their dose of anti-inflammatory pain relievers because of this capsule.
However, there isn't enough research to recommend nettle as an anti-inflammatory treatment. More human studies are needed.
Summary: Nettle may help suppress inflammation, which in turn may help inflammatory conditions, including arthritis, but more research is needed.
Up to 50% of men 51 and older have an enlarged prostate gland.
An enlarged prostate is commonly called benign prostatic hyperplasia (BPH). Scientists aren't sure what causes BPH, but it can cause significant discomfort during urination.
Interestingly, several studies have shown that nettle can help treat BPH.
Изследванията върху животни разкриват, че това мощно растение може да предотврати превръщането на тестостерона в дихидротестостерон – по-мощна форма на тестостерон.
Stopping this conversion can help reduce the size of the prostate.
Проучвания при хора с ДПХ показват, че екстрактите от коприва помагат за лечение на краткосрочни и дългосрочни проблеми с уринирането – без странични ефекти.
However, it is not clear how effective nettle is compared to conventional treatments.
Summary: Nettle can help reduce the size of the prostate and treat symptoms of an enlarged prostate gland in men with BPH.
Hay fever is an allergy that involves inflammation in the lining of the nose.
Nettle is seen as a promising natural treatment for hay fever.
Test-tube studies show that nettle extracts can inhibit the inflammation that can trigger seasonal allergies.
This involves blocking histamine receptors and stopping immune cells from releasing chemicals that cause allergy symptoms.
However, human studies have noted that nettle is equal to or only slightly better at treating hay fever than a placebo.
Although this plant may prove to be a promising natural remedy for hay fever symptoms, longer-term human studies are needed.
Summary: Stinging nettle can reduce the symptoms of hay fever. Still, some research suggests it may not be much more effective than a placebo. More research is needed on the effects of nettle on hay fever.
High blood pressure is a serious health problem because it puts you at risk of heart disease and stroke, which are among the leading causes of death worldwide.
Nettle is traditionally used to treat high blood pressure.
Animal and test-tube studies show that it can help lower blood pressure in several ways.
On the one hand, it can stimulate the production of nitric oxide, which acts as a vasodilator. Vasodilators relax the muscles of the blood vessels, helping them to widen.
In addition, nettle has compounds that can act as calcium channel blockers, which relax your heart, reducing the force of contractions.
In animal studies, nettle has been shown to lower blood pressure levels while increasing the heart's antioxidant defenses.
However, the effects of nettle on blood pressure in humans are still unclear. Further human research is needed before recommendations can be made.
Summary: Nettle can help lower blood pressure by allowing blood vessels to relax and reducing the force of the heart's contractions. Still, more human research is needed to confirm these effects.
