 Nettle Root and Nettle Seed are remedies that should be considered separate from the aerial parts of the plant. Nettle Root is mostly used as a decongestant for the prostate or androgen excessive conditions. It works as an astringent, anti-diarrheal, mucostatic, detoxicant, and dissolvent for cold, damp conditions in the urinary or reproductive systems. Nettle Seed is used as a general restorative for weak deficiency conditions of all types. The presence of phytohormones and fatty oil makes it specifically a thyroid stimulant in a functional  hypothyroidism and immune stimulant for toxic insect bites or the ingestion of a poisonous plant.

Topical Preparation use:

Nettle leaf can be used externally as an alcoholic liniment prepared with fresh herb to aid in rheumatic and neuralgic pains. Washes and compresses can also be used for degenerative and arthritic musculoskeletal conditions for pain relief and deep level treatments. 

Wet cotton, drops, or irrigation with fresh juice has also been used to treat nosebleeds. Nettle Root has also been used as hair rinse for hair loss or weak hair by creating a diluted herbal vinegar decoction with Rosemary and/or Birch leaf.

Nettle can also be infused in skin ointments or lotions alongside Calendula, Burdock, and Figwort for a general dermal remedy. 

Many have also reported that stinging oneself with the fresh plant around stiff or painful joints can bring relief due to the anti-histamine action, serotonin, and blood rush to the area. Medicine for masochists.

Stinging Nettle is extremely nutrient dense, high in protein, and packed with Vitamins A, C and K, as well as several B vitamins, calcium, non-heme iron, magnesium, phosphorus, potassium and sodium, fats such as linoleic acid, linolenic acid, palmitic acid, stearic acid and oleic acid, all of the essential amino acids and phytonutrients such as polyphenols, chlorophyll, and pigments. 

Nettles Relationship to Hormone Regulation

For most healthy individuals, High levels of estrogen and testosterone are damaging only after they have become bound to Sex Hormones Binding Globulin (SHBG). Once estrogen or testosterone have become bound to SHBG, they begin the process of being converted into harmful estrogen metabolites, like estradiol. By keeping these sex hormones free, the rates of conversion to harmful metabolites are decreased. Nettle Root has the unique ability to optimize functions of the endocrine system and hormones specifically related to reproductive health. In females, Nettle Root works by blocking SHBG which has an affinity for all sex hormones, and keeping levels of free estrogen is important. For men, Nettle Root even works to unbind testosterone which has already become bound by SHBG, further increasing levels of important free testosterone and further decreasing the conversion to estrogen metabolites.

Nettles Relationship to Blood

Nettle is an excellent blood trophorestorative due largely to it’s high nutrient content. It stimulates production of red blood cells which replenishes the blood and enhances and regulates metabolic function. This is also beneficial for stagnant or absent periods. In my personal experience, a infusion of stinging nettle sipped throughout the day during menstruation helps my own PMS symptoms including pain, irritability, and overall quickens the pace of my flow.

Nettles Relationship to Allergies and Respiration

The Leaves and stems of stinging nettle have the ability to treat seasonal allergies in some cases due to its anti-inflammatory effects as well as it’s phytonutrient content. The best preparation for this seems to be a syrup made with Mullein flower, Elecampane root and Coltsfoot. Smoking the dried herb in small puffs may also bring asthmatic relief.
