Nettle leaf is a well-known herb. The nettle root is little known but is an effective medicine. It combines well with saw palmetto for the treatment of prostatic symptoms. Like Serenoa, nettle root inhibits the breakdown of testosterone into dihydrotestosterone. The mechanism for this is believed to be its inhibition of both 5-alpha-reductase and aromatase. While nettle root is less effective than saw palmetto, the two together or with pygeum have greater activity than either herb by itself... 

Nettle leaf (Urtica dioica) has a long tradition of being used for weak, unhealthy, or falling hair. The dried leaf can be made into a tea, which is used as a rinse. It is used to nourish the hair, reduce sebum production on the scalp, and reduce hair loss.

Fresh stinging nettle leaf causes skin irritation and should be used with care. Uncooked fresh nettle should not be consumed. 

A review of clinical studies of stinging nettle leaf indicated that no serious adverse events were reported in five clinical studies with a total of 10,368 participants taking 670 mg twice daily of a dried hydroethanolic extract ( 9.7 g dried leaf) for 3 to 52 weeks. Minor gastrointestinal upset or allergic reaction occurred in 1.2 to 2.7% of participants (ESCOP 2003). Abdominal gas was reported in 3 of 19 patients...

Animal studies have demonstrated that stinging nettle leaf may modify glucose regulation (Bnouham et al. 2003 Farzami et al. 2003 Swanston-Flatt et al. 1989). People with diabetes are advised to monitor their blood sugar closely and discuss the use of this herb with a qualified healthcare practitioner prior to use. 

Limited information on the safety of stinging nettle leaf in pregnancy or lactation was identified in the scientific and traditional literature. Although this review did not identify any concerns for use while pregnant or nursing, safety has not been conclusively established. 

Immediate and delayed hypersensitivity to stinging nettle leaf was reported in a boy who fell into a stinging nettle patch. Urticaria was present for 12 hours, and a fine vesicular rash erupted at 48 hours (Edwards 1992). A case of severe tongue edema was reported in a woman who placed a fresh leaf of dwarf stinging nettle (U. urens) on her tongue (Caliskaner et al. 2004). 

An open study in patients with myocardial or chronic venous insufficiency indicated that administration of 45 ml stinging nettle leaf juice daily caused an increase in the volume of urine of patients. The effect was more pronounced in patients with chronic venous insufficiency, with a 24% increase in urine volume in this group as compared to a 9% increase in the myocardial insufficiency group (Kirchhoff 1983). 

Hypotensive, diuretic, and natriuretic activity of an aqueous extract of stinging nettle leaf was observed in anesthetized rats intravenously administered a continuous perfusion at a rate of 4 mg/kg per hour or 24 mg/kg per hour for 1.25 h. The decrease in arterial blood pressure was reduced by 15% at the lower dose and 38% at the higher dose (Tahri et al. 2000). A rapid but transient blood pressure decrease of 37% in rats was observed after intravenous administration of an aqueous extract of 25 mg/kg stinging nettle leaf (Lasheras 1986). In cats, administration of 26.6 mg/kg produced a hypotensive effect and bradycardia that was not compensated by administration of adrenaline (Broncano 1983). 

A fraction of a water-methanol extract of stinging nettle leaf produced a marked decrease of inotropic activity in spontaneously beating atria of guinea pigs as well as marked but transient hypotensive activity on the blood pressure of anesthetized rats (Testai et al. 2002). 

Case reports indicate that horses exposed to stinging nettle leaf sometimes become distressed and develop ataxia and muscle weakness. Such incidents of stinging nettle exposure are often accompanied by the characteristic nettle rash (Bathe 1994 Conwell and Findlay 2008). 

Teeth decay after eating sugar, and one of the first metabolites from sugar is lactic acid Rubbing a dock leaf (which contains an organic base) on the site of a nettle sting (which contains acid) will neutralize the acid and relieve the pain...

Add the nettles (being careful not to touch them with your bare hands ), bay leaf or bouquet garni, and stock or water. 

Screening involved evaluation of 220 candidate botanical ingredients in vitro for their ability to inhibit ILlp gene expression in human mononuclear cells (U937 and THP-1) that were stimulated with lipopolysaccharide (LPS) (Table 11.1, activity 2). The ingredient list was narrowed to twenty-six botanicals that had a 50% inhibitory concentration of <10 pg/ml in the in vitro IL-1 production assay. The potential IL-1 inhibitors were further narrowed to four botanicals (artichoke leaf extract, nettle root extract, olive fruit extract, and rose hips extract) based on criteria such as reliability of sourcing, purity, and others that might contribute to commercial potential. 

An old remedy to relieve the prickly sting of a nettle plant is to rub the area with the leaf of a dock plant. The sting contains an acid. This acid is neutralized by a base that is present in the dock leaf. Bees and ants also have an acidic sting. You can wash the sting with soap, because soap is basic. 

There are many kinds of natnral fibers, snch as bast fibers (flax, hemp, jute, kenaf, ramie, nettle, and mesta), leaf fibers (sisal, heneqnen, pineapple, abaca, oil palm, and screw pine), seed fibers (cotton), frnit fibers (coconnt hnsk, or coir), and stalk fibers (straw of varions kinds). They are not nsed for commercial WPG, primarily on economical reasons (except maybe Procell, see Table 1.1). Most of these fibers have fonnd applications in established indnstries, snch as textile indnstry (cotton, flax, jnte, ramie, hemp, and sisal) and paper indnstry (straw).

Chapters 2-10 discuss in detail the different properties of natural lignocellulosic fibers, their processing and fabrication of polymer composites. Chapter 11 summarizes the structure, chemistry and properties of different agro-residual fibers such as wheat straw corn stalk, cob and husks okra stem banana stem, leaf, bxmch reed stalk nettle pineapple leaf sugarcane oil palm bunch and coconut husk along with their processing. 

Natural fibers are basically derived from three natural resources, which are plants, animals, and minerals. Fibers from plants can be obtained from leaf (sisal fibers), bast (nettle fibers), seed (cotton), fruit (coconut) and wood (hard and softwood). Silk, wool and feathers are examples of animal fibers. Natural fibers from plants are widely used in fabrication of biocomposites for various applications [5].
