Ginseng is another adaptogen that increases the body’s ability to cope with physical, emotional, and environmental stress. The greater the body’s need for an adaptogen, the increasingly more active the substance becomes. All the adaptogens have been well studied and their safety repeatedly documented. Panax ginseng has been shown to improve overall sexual functioning in men with erectile dysfunction. Creams containing the compound are also available to treat premature ejaculation.
Feeling fatigued, very stressed, depressed or dealing with another mood-related issue that can lower libido. Sources of stress and diminished quality of life — such as “deteriorating economic position,” unhappiness with one’s job or other aspects that lower emotional health — are believed to be major causes for sexual dysfunction in both men and women
Yohimbine is the principal alkaloid of the bark of the West African evergreen P johimbe (formerly known as C johimbe), family Rubiaceae. The main active chemical present in P johimbe bark is yohimbine hydrochloride (an indole alkaloid), which has stimulant and aphrodisiac effects. However, the levels of yohimbine that are present in P johimbe bark extract are variable and often very low. Therefore, although P johimbe bark has traditionally been used to treat ED , there is insufficient scientific evidence to form a definitive conclusion in this area. It is an antagonist of α2-receptors and has no direct relation to erection. It acts as a sex motivation stimulant. Yohimbine has been used as both an over-the-counter dietary supplement in the form of an herbal extract, and as a prescription medicine in purified form for the treatment of sexual dysfunction. Yohimbine 20 mg or adjusted dose has been found to be effective in the treatment of orgasmic dysfunction. Yohimbine was recently associated as a treatment for type 2 diabetes mellitus in animal and human models carrying polymorphisms of the alpha-2A adrenergic receptor gene . The National Institutes of Health states that yohimbine hydrochloride is the standardized form of yohimbine that is available as a prescription medicine in the United States, and has been shown in human studies to be effective in the treatment of male impotence. Yohimbine hydrochloride USP has been used to treat ED. Controlled studies suggest that it is not always an effective treatment for impotence, and evidence of increased sex drive (libido) is anecdotal only. It cannot be excluded that orally administered yohimbine can have a beneficial effect in some patients with ED. The conflicting results available may be attributed to differences in drug design, patient selection and definition of positive response. Yohimbine has been shown to be effective in the reversal of sexual satiety and exhaustion in male rats, and has also been shown to increase the volume of ejaculated semen in dogs, with the effect lasting at least 5 h after administration. Yohimbine has also been shown to be effective in the treatment of orgasmic dysfunction in men, and has also been used for the treatment of sexual side effects caused by some antidepressants, and female hyposexual disorder. Yohimbine has significant side effects, such as anxiety reactions. Higher doses of oral yohimbine may create numerous side effects, such as rapid heart rate, high blood pressure, overstimulation, insomnia and/or sleeplessness. More serious adverse effects may include seizures and renal failure. Yohimbine should not be consumed by individuals with liver, kidney or heart disease, or psychological disorders. The therapeutic index of yohimbine is low; the range between an effective dose and a dangerous dose is very narrow. Side effects include gastrointestinal upset, increased blood pressure, headache, agitation, rash, tachycardia and frequent urination .
Eleutherococcus senticosis (Siberian Ginseng) is an overall system toner and improves performance and stamina. In the 1950's it was used extensively by Soviet athletes to enhance athletic performance. It can combat stress and is a tonic stimulant for the adrenal hormones. One of the most important active ingredients in Siberian or Oriental Ginseng is the ginsenosides, which greatly promote blood flow to the brain and peripherals, including the penis. In oriental medicine, Ginseng is highly respected and prized as a herb which promotes male or 'yang' energy, improving circulation, boosting vitality and acting as an overall systemic invigorator.
Erectile dysfunction (ED) or male impotence is defined as inability of a man to achieve or maintain penile erection sufficient for sexual activity. It is primarily a neuronal and endothelial dysfunction of the corpus cavernosum of penile tissue, and is partly characterized by reduced production of nitric oxide (NO). Other factors that may contribute to the pathogenesis of ED include androgen deficiency in aging men, hypertension, high cholesterol levels, atherosclerosis, diabetes mellitus, diseases of the prostate and heart, and anatomical deformity of the penis. ED may also be caused by some medications, prostate surgery and spinal cord injury. Psychological and social conditions such as stress, depression and unhappy marital relationship may contribute to the problem. Chronic infections and inflammation can also contribute to the disease process. ED is linked to an increased risk for cardiovascular diseases and stroke. Several orally active drugs (sildenafil, vardenafil, tadalafil, avanafil) are currently prescribed for treating ED to improve the arterial blood flow to the penile tissue. Medicinal plants and their extracts have been used in traditional medicine in southwest Asia and other countries to treat ED. The current review focuses on four medicinal plants that have been used as aphrodisiacs for enhancing sexual performance and for the treatment of ED. These plants include Eurycoma longifolia Jack (tongkat ali); Chlorophytum borivilianum (safed musli); Withania somnifera (ashwagandha); and Pausinystalia johimbe (formerly known as Corynanthe johimbe). Suggested mechanisms of action for each of the plant extracts will be discussed.
Tribulus terrestris (6): this plant has long been used as a folk medicine in Eastern Europe and Bulgaria for sexual deficiency (5). The properties of this powerful ingredient have been associated with an increase in sperm production, sexual endurance, and testosterone levels. Also known as puncture vine, this herb has gained popularity over the past few years. Since testosterone plays a huge role for men, the addition of this herb can prove to be very beneficial. It is not a hormone as some believe. It is said that Tribulus terrestris can also help build muscle and strength, which enhances performance (5,7).
