NETTLE (Urtica dioica) Leaf
About this Herb
Hippocrates had around 61 different Nettle preparations. The Greek medical scripture ‘De Simplicibus’ suggests Nettle for ‘a diuretic and laxative, for dog bites, gangrenous wounds, swellings, nose bleeding, excessive menstruation, spleen-related illness, pleurisy, pneumonia, asthma, tinea, and mouth sores.’ Later additions included Nettle mixed with Hemp plant for relief from shock as well as Nettle on its own being used for shingles and constipation.
With Benign Prostate Hyperplasia (BPH), affecting many men as they age, recent studies have found that Nettle is effective in reducing prostate size. It not only reduces the prostate size, it also alleviates the symptoms such as the frequent urge to urinate, painful urination and incomplete emptying of the bladder.
It is thought that the bioactive phytochemicals in Nettle exert a series of complex effects on the prostate. These active ingredients can inhibit the binding of the androgenic steroid hormone to sex hormone binding globulin (SHBG).
SHBG is a glycoprotein that preferably binds to testosterone and oestrogen, although it also binds to other sex hormones. It is involved in the transportation of these sex hormones through the plasma and their delivery to receptors in various target organs including the prostate.
When testosterone is unable to bind to this glycoprotein, the prostate receives far lower amounts of the hormone. In addition, testosterone metabolites such as DHT (dihydrotestosterone, also implicated in the enlargement of the prostate), cannot get to the prostate. As a result, excessive androgen stimulation of the prostate is prevented and the symptoms of BPH are relieved. The bioactive lignans present in Nettle Root Extract are believed to be responsible for this effect.
It must be remembered that Nettle leaf works well for inflammation of the prostate (prostatitis) and other inflammation whilst the Nettle root is much better for BPH.
A small, placebo-controlled British study looked the effectiveness of Nettle for the relief of osteoarthritis pain. Participants who applied stinging Nettle to painful joints for one week reported significantly greater reductions in pain than those who used the placebo.
In another study, scientists used a Nettle Leaf extract to observe its effects on dendretic cells. Dendretic cells play an active role in the initiation of rheumatoid arthritis. Nettle Leaf extract was able to keep dendretic cells from growing, but did not kill the cells. It also reduced the number of protein genes associated with rheumatoid arthritis. Probably the most significant observation in this study was that Nettle Leaf extract had a positive effect against the genes associated with rheumatoid arthritis. Nettle was also able to curb T cell (or white blood cell) proliferation, reducing infection.
Kidney and Gallbladder Health
Nettle has long been known as an effective diuretic, however it also has nephridic qualities – meaning that it can help to break down stones in the kidney and gallbladder, preventing these painful conditions from worsening or requiring those stones to be either passed or surgically removed. Also, as a diuretic, stinging nettle helps to eliminate toxins quickly, thereby protecting against bladder infections.
Used as a tea from the leaf and root. Taken also in powdered root form for medical purposes. The young shoots are used in cooking and for dying cloth while the fibre was used to make cordageacetophenone, 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.
Nettle Root is considered safe but some people may experience mild stomach upset or fluid retention.
