Stining Nettle Summary:
Stinging nettle is a small, perennial herb found growing all over the world. Its leaves are covered in tiny hairs that cause a painful stinging sensation upon contact with the skin. The hairs contain a slurry of chemicals to cause this sting including histamine, serotonin, choline, and formic acid (also found in bee stings).
Stinging nettle has a high level of nutrition, and contains a rich source of minerals, vitamins, amino acids, chlorophyll, lecithin, carotenoids, sterols, and tannins.
The leaves and root of the plant are both used, however, they are useful for different conditions. The root is best for benign prostatic hyperplasia, and hair loss. The leaves on the other hand are best for inflammation, prostatitis, allergies, and as a diuretic.
One of the most unique uses of this plant is also one of the oldest, dating back some 2000 years. Urtication, is the process of rubbing or slapping the fresh leaves against swollen or arthritic joints, with the ironic goal of relieving pain and inflammation. The stinging hairs are suggested by many to act as a distraction from the pain of arthritis, however, there is clearly more going on here than this simple explanation. Contained within the hairs are potent blend of chemicals. Some of these chemicals directly signal inflammation to subside, others trigger a histamine response which then causes the body to launch an antihistamine response that ends up with a reduced level of inflammation after a few minutes.
Stinging nettle tea is also great for a hangover, the high level of nutrition, including minerals, help to revitalize the body's electrolytes after a night out. Other benefits of stinging nettle is combating benign prostatic hyperplasia, anti-allergic effects, detox support, treating hair loss, anti inflammatory support, cleansing the blood, antimicrobial actions, diuretic, lowers blood pressure, nutritive, analgesic, stops bleeding, vulnerary, stimulates digestion, aids lactation, promotes regular menstrual cycles, and helps to revitalize individuals with weak disposition.

Stinging nettle is a perennial herb that is grown all over the world, mainly in temperate and tropical areas. It grows to about 2-4 m high.
The leaves are pointed, elliptical, with small stinging hairs on the leaf surface. Its name is due to these stinging hairs. Urtica comes from the latin word "urere", which means “to burn”. The species name dioica means “2 horses” likely due to the presence of 2 separate plants for male and female. .
Habitat Ecology, and Distribution:
Generally, stinging nettle is found in waste areas, and areas with nitrogen rich soils .
Harvesting Collection, and Preparation:
This herb can easily be grown at home in the garden or in a window sil, Just be cautious of the stinging hairs on the leaves and wear gloves whenever handling this plant.
The sting associated with stinging nettle is due to a slurry of chemicals contained in the leaves surface hairs. Some of these chemicals includes formic acid, the indoles histamine and serotonin, and aetylcholine. [2-4].
The plant also contains a rich source of minerals chlorophyll, amino acid, lecithin, carotenoids, flavonoids, sterols, tannins, flavonol glycosides (isohamnetin, kaempferol, quercetin), and vitamins (vitamin C and vitamin K), proteins, dietary fiber, nitrates, and silicon (mainly in the stinging hairs) [2-4].
Nettle leaf contains acetophenone, acetylcholine, agglutinins, alkaloids, astragalin, butyric acid, caffeic acids, carbonic acid, chlorogenic acid, chlorophyll, choline, coumaric acid, folacin, formic acid, friedelins, histamine, kaempherols, koproporphyrin, lectins, lecithin, lignans, linoleic acid, linolenic acid, neoolivil, palmitic acid, pantothenic acid, quercetin, quinic acid, scopoletin, secoisolariciresinol, serotonin, sitosterols, stigmasterol, succinic acid, terpenes, violaxanthin, and xanthophylls. [2-4].
The root contains chemicals such as scopoletin (a coumarin), sterols, fatty acids, polysaccharides, isolectins, steryl glycosides (sitosterol), lignans, phenylpropanes, and polyphenols. [2, 4].
Pharmacology and Medical Research:
Some of the traditional uses on treating allergies, and in particular allergic rhinitis have been supported by a couple of studies identifying the mechanism of action for this condition it was suggested that these effects were the result of nettles ability to inhibit various inflammation triggering cytokines, prostaglandins, and leukotrines. .
Some of nettle leafs ability to combat inflammation is suggested to be through its ability to block the production of various inflammatory cytikines, prostaglandin and leukotrines .
Benign Prostatic Hyperplasia
The root is suggested to be much more useful than the leaves of the plant for benign prostatic hyperplasia. Several older studies have began investigating the possible mechanisms of action for this. Some of these findings have suggested that a lignan component of stinging nettle was able to reduce the binding activityof human sex hormone binding globulin in vitro., they work by coompetitively binding to this hormone which prevent s it ffrom binding to 5-alpha-dihydrotestosterone (DHA). Various in vivo studies have reported a reduction in prostate growth after long term oral treatments of stinging nettle root. .
Nettle leaf water extracts were noted to lower blood pressure, reduce heart rate, and had notable diuretic action. It was even found to be more effective than the pharmaceutical furosemide at reducing blood pressure, and increasing urine output and sodium excretion. [2, 4].
A vasorelaxant action from a stinging nettel root extract was reported to be act through a release of endothelial nitric oxide, and an opening of potassium channels. A negative inotropic action in the atria of guinea pigs was also reported with the oral intake of nettle root extracts .
Nettle leaf has also been found to inhibit platelet aggregation in vitro /.
