About horny goat weed, Epidemium, and its medical and sexual use

Botanical information

Botanical Names differ according to what exact species of epidemium that is used: 1. Epimedium koreanum Nakai; 2. Epimedium sagittatum (Sieb. et Zucc.) Maxim.; 3. Epimedium brevicornum Maxim.; 4. Epimedium pubescens Maxim. Barrenwort, Herba Epimedii, Horny Goat Weed, Japanese Epimedium, Xian Ling Pi, Yin Yang Huo. Epimedium acuminatum; Epimedium grandiflorum; Epimedium wushanese, and other Epimedium species.

Natively one finds Epidemium variants mainly in China, in some other Aian areas and to some extent in the Mediterranean area. The green parts of the plants last for one season, for some species a year, and for just a few species several years. The flowers are symmetrical with four of each part in the flower.

The flowers have four small outer greenish sepals which often fall off when the flower opens. Inside these are four other brigntly colored sepals that look like petals. More inside are the true, often small, but complicated shaped petals, and with a nectar-producing spur. There are four stamens. Also the style is four-fold with four stigmas and four-fold ovary.

Varying according to species there are one or several thightly assambled stems. Some species have only one leaf at the base of the stem, while others have several of them along the stem. The leaves are typically compunded with three leaflets with spiny margines.

Epidemium belongs to the family Berberidaceae. Source of warliest record is Haiyao Bencao.

How the plant is prepared

Part Used & Method for Pharmaceutical Preparations : The aerial part of the herb is gathered in spring and autumn, dried in the sun and cut into pieces.

The medical effects of epidemium

Hornry Goat Weed increases energy, libido, sperm production, stimulates the sensory nerves  and increases sexual desire. In addition, research has shown that Horny Goat Weed has anti-fatigue effects and helps prevents adrenal exhaustion. The herb has also been traditionally used for liver and kidney tonification.

Horny Goat Weed`s aphrodisiac effects has been verified in both animal and human research. Mice treated with a Horny Goat Weed preparation produced "apparent effects on the improvement of sexuality." It was also shown to improve sperm producing capability. Since Horny Goat Weed has been traditionally used for kidney disease, it's interesting that research has demonstrated a sexual potentiation effect and improved quality of life in patients with chronic renal failure who were given Horny Goat Weed.

Animal studies using epimedium have shown a reduction in bone breakdown, an increase in muscle mass, and a loss of body fat-each of which may be linked to the observed return of abnormal cortisol levels back to normal values (and rhythm). In a series of studies conducted in humans and animals by Chinese researchers, immune-system function was directly suppressed and bone loss was accelerated, by using high-dose synthetic cortisol (glucocorticoid drugs). Subsequent administration of epimedium extract reduced blood levels of cortisol and improved immune immune-system function (in the humans) and slowed bone loss and strengthened bones (in the animals).

Epidemium as further been used for treatment of
impotence, involuntary ejaculation, weak back and knees, arthralgia, mental and physical fatigue, memory loss, hypertension, coronary heart disease, bronchitis, chronic hepatitis, polio, chronic leukopenia, viral myocarditis.

Research has shown that Horny Goat Weed significantly increases testosterone in mice. This certainly appears to be one of the herb's mechanism of action, although Horny Goat Weed may have more than one. For example, it has been established that sexual arousal is linked to the activity of cholinergic neurotransmitters. However, an enzyme called acetylcholinesterase (AChE) inactivates cholinergic neurotransmitters within 1/500 of a second. As it turns out, research shows that Horny Goat Weed is capable of inhibiting AChE. Such an inhibition may support higher levels of the key cholinergic neurotransmitters associated with sexual arousal. It also seems to restore production of thyroid hormones when these are in defiency.

Traditional use

Horny Goat Weed is a traditional botanical medicine used in China and Japan. Although this herb (which also goes by the names Yin Yang Huo, Inyokaku, and Herba Epimedii) has a history of traditional use for disorders of the kidneys, joints, liver, back and knees, its principle use is as an aphrodisiac.

The mechanism of the sexual action of epidemium

The active ingredient in Epimedium is icariin, which can be found in standardized extracts from 5% up to 60% consentration.

Icariin seems to increase the leverl of nitrix oxide in tissues releasing this compound, and thus it increases the elevel of this compound in the penile and genital tissues of men. Nitric oxide relaxes smooth muscles in the blood vessels leading blood to the penis and in the network of blood vessels within the penis. This causes the penis to be filled with blood and engorge.

There has been done scientific experments where icariin has been injected into the penile tissues in rats, and these experiments have demonstrated the relaxation of smooth muscles within the penis and an increased penile blood pressure.

Icariin inhibits the activity of PFE5.  PFE5 is an enzyne that breaks down the compound cGMF. Thus the action of icariin increases the amount of cGMF in the penile tissue and other tissues. cGNF is a tool used in the production of nitric oxide. Therefore Icariin wil increase the amount of nitric oxide in the penile tissues.

About PFE5 ( PFE-5 ) or cGMP specific phosphodiesterase type 5

This is an enzyme in the phosphodiesterase class. It is found in various tissues, most prominently the corpus cavernosum and the retina.

The phosphodiesterase (PDE) isozymes, found in several tissues including the rod and cone photoreceptor cells of the retina, belong to a large family of cyclic nucleotide PDEs that catalyze cAMP and cGMP hydrolysis.

The interest in PDEs as molecular targets of drug action has grown with the development of isozyme-selective PDE inhibitors that offer potent inhibition of selected isozymes without the side effects attributed to nonselective inhibitors such as theophylline.

A PDE5 inhibitor that is significantly more potent and selective than zaprinast (an early PDE5 inhibitor) and comparable in its PDE inhibitory properties to sildenafil (Viagra, 1998), a drug recently approved for the treatment of male erectile dysfunction.

PDE5 is an enzyme that accepts cGMP and breaks it down. The kinetics of binding [3H]sildenafil and [3H]tadalafil to the catalytic site of PDE5.

Both inhibitors bind with high affinity and specificity, and cGMP binding to the allosteric sites stimulates binding of PDE5 inhibitors at the catalytic site. The kinetics of inhibitor binding and inhibition of catalysis imply the existence of two PDE5 conformers, and results of native gel electrophoresis reveal that PDE5 exists in two apparently distinct conformations, i.e., an extended conformer and a more compact conformer.

PDE5 activity is modulated by a rapidly reversible redox switch. Chemical reduction of PDE5 relieves autoinhibition of enzyme functions; allosteric cGMP-binding activity is increased 10-fold, and catalytic activity is increased ~3-fold. The redox effect on allosteric cGMP-binding occurs in the isolated regulatory domain. A change in the state of reduction of PDE5 or the isolated regulatory domain is associated with an apparent conformational change similar to that caused by phosphorylation.

PDE5 is expressed in human colonic cells and in intestinal tissue and its activity is regulated by intracellular cGMP levels in these cells that increase on GCC activation. This presumably occurs through binding of cGMP to the GAF domains in the N-terminus of PDE5, resulting in allosteric activation of the enzyme.

The mechanism of action of E4021 on both the nonactivated and activated forms of rod PDE6 because both states are relevant to understanding how PDE5-selective inhibitors may alter signal transduction pathways in photoreceptor cells. PDE5-selective inhibitors may show good discrimination of PDE5 from most other PDE isoforms.

cGMP or Cyclic Guanosine Monophosphate

Cyclic guanosine monophosphate (cGMP) is a cyclic nucleotide derived from guanosine triphosphate (GTP). cGMP acts as a second messenger much like cyclic AMP, most notably by activating intracellular protein kinases in response to the binding of membrane-impermeable peptide hormones to the external cell surface.

cGMP synthesis is catalyzed by guanylate cyclase (GC), which converts GTP to cGMP. Membrane-bound GC is activated by peptide hormones such as the atrial natriuretic factor, while soluble GC is typically activated by nitric oxide to stimulate cGMP synthesis.

cGMP is a common regulator of ion channel conductance, glycogenolysis, and cellular apoptosis. It also relaxes smooth muscle tissues. In blood vessels, relaxation of vascular smooth muscles lead to vasodilation and increased blood flow.

cGMP is a secondary messenger in phototransduction in the eye. In the photoreceptors (rods and cones) of the human eye, the absence of light activates phosphodiesterase, which upregulates cGMP by catalyzing its conversion from guanosine monophosphate (GMP). cGMP opens sodium ion channels, which leads to the depolarization of the photoreceptor's plasma membrane, which opens calcium ion channels, which leads to the release of neurotransmitters by the photoreceptor cell, which in turn signals other cells inbedded in the retina and leads to the transfer of information from the eye to the brain and vision.

Cyclic nucleotide phosphodiesterases (PDE 1-6) breakes down cGMP by hydrolyzing cGMP into 5'-GMP.

Phosphodiesterase inhibitors prevent the breaksown of cGMP, thereby enhancing and/or prolonging its effects. For example, Sildenafil (Viagra) enhances the vasodilatory effects of cGMP within the corpus cavernosum by inhibiting PDE 5 (or PDE V). This is used as a treatment for erectile dysfunction.
