Yohimbe Bark Extract
(the most popular aphrodisiac in the world)

Yohimbe Bark Extract works by expanding the blood vessels in the genital area. For men, it increases the formation of Nitrous Oxide, a natural substance that is important for producing an erection. Physiologically, Yohimbe is shown to increase fulfillment and sensation. Yohimbe is a common natural Viagra ingredient found in many herbal impotency treatments and has been used for centuries to treat sexual dysfunction and enhance virility. Yohimbe works to increase blood flow to the genitals in both men and women and increases the nerve impulses to the pelvic area. Yohimbe has a general stimulating effect on the nervous system to open blood vessels, increase sensitivity and heighten libido. This effect from Yohimbe is essential for increased circulation to the genital area where sensitivity and blood flow is enhanced. Yohimbe bark has also been shown to be effective in treating impotence in men and women caused by psychological reasons, such as stress, tension or fatigue. Yohimbe can regain lost sexual function. Yohimbe improves sexual function without side effects and has been effective in treating impotency in patients with kidney disease and diabetes. Yohimbe provides a boost to the body's ability to perform sexually and stimulates sexual potency by reducing the effects of hormones in the body that cause constriction of blood vessels. Yohimbe has been used for thousands of years to treat lacking sex drive and performance. The active component of yohimbe bark is yohimbine, an alkaloid monoamine oxidase (MAO) inhibitor that blocks adrenergic receptors. This leads to an increase in dilation of blood vessels and a lowering of blood pressure. This enlargement of blood vessels, particularly in the sexual organs, is the generally accepted explanation of the physiological effects of the herb. Yohimbe also seems effective in elevating mood and reducing depression and anxiety, further contributing to its aphrodisiac activity. It has been widely used in Europe for about 75 years to treat male erectile dysfunction, formerly called impotence. The U. S. Food and Drug Administration (FDA) approved yohimbe as a treatment for impotence in the late 1980s. It also prevents blood from flowing out of the penis during an erection. It may also act on the central nervous system, specifically the lower spinal cord area where sexual signals are transmitted. Studies show it is effective in 30-40% of men with impotence. It is primarily effective in men with impotence caused by vascular, psychogenic, or diabetic problems. In men without erectile dysfunction, yohimbe in some cases appears to increase sexual stamina and prolong erections. Thousands of Urologists in the U.S. and abroad have been recommending the drug forms of Yohimbe for years. Many studies have shown that Yohimbe can help impotence caused by poor circulation, (i.e. age, diabetes, emotional problems, etc.) A recent clinical study in Rhode Island (published in the Journal of Urology) tested the active ingredient in yohimbe on a group of men who had experienced chronic sexual dysfunction. For those who had been impotent for less than two years the improvement rate was an astounding 81% as a direct result of consuming a moderate dosage over a period of one month. The Rhode Island study also showed that two thirds of the men who had reported having only a partial erection or erections of a short duration, and had failed in normal intercourse at least 50% of the time, reported fuller and longer lasting erections, leading to consistently successful lovemaking. The effects of Yohimbe start around 30 minutes after ingestion and last around two hours; however, the full beneficial effect begins after 2 to 4 weeks of continuous daily use. Yohimbe expands the blood vessels in the extremities of the body including the genitals (similar to the prescription drug Viagra), skin and even fat cells. Yohimbe acts as an alpha adrenoreceptor blocker reducing the effect of hormones that cause constriction of blood vessels, which typically increases as we age. Yohimbe particularly aids blood flow to the corpus cavernosom to more readily engorge the penis. Yohimbe concurrently increases the body's production of norepinephrine which is essential to the formation of erections and steps up adrenaline to nerve endings which enhance sexual stimulation.

Niacin

Niacin (vitamin B3) is an essential vitamin found in many foods. The human body uses niacin in more than 50 chemical reactions. Niacin works in the body to dilate capillaries causing in increase of blood flow to the peripheries.1,2 A common form of niacin, called niacinamide, is found in most vitamin and mineral supplements, but does not have the vasodilatory affects associated with niacin.

Tribulus Terrestris

This herb, commonly known as puncture vine, has long been used among Ayurvedic practitioners for the treatment of genito-urinary tract disorders and liver tonic. Tribulus Terrestis has however in recent times shown its effectiveness in improving sexual function. Studies in the 1980's showed further convincing evidence of its action on sexual function. Tribulus Terrestis also contains powerful steroid saponins (furostanol type) which have been used traditionally to improve the libido. Studies performed in Europe concluded that supplementation with tribulus could increase testosterone levels by 30% or more in just five days.
Tribulus terrestris is a perennial plant, which grows predominately in India and Africa. Tribulus is mentioned in ancient Indian Ayurvedic medical texts dating back thousands of years. Tribulus has been used widely in the Ayurvedic system of medicine for the treatment of sexual dysfunction and various urinary disorders.
In one study, Tribulus terrestris increased spermatogenesis and sexual activity in laboratory animals. Tribulus terrestris appears to raise/turn on natural testosterone production in men via the activation of hormone secretion and estradiol. Clinical studies in Bulgaria have shown Tribulus terrestris to increase the sex hormones LH (luteinizing hormone) level by 72% and the body's own free testosterone level by 41% in healthy adult males in only five days. LH regulates the testosterone production in the testes and high levels of LH coincide with high testosterone levels. Tribulus has become increasingly popular with athletes because it reportedly increases strength and stamina. Studies into Tribulus' uses are ongoing. It is a botanical that has been used for hundreds of years in Europe for hormone insufficiency in men and women. It is widely believed that Tribulus is the closest and strongest natural herbal alternative to synthetic hormones. Although Tribulus grows in many parts of the world including India, China and Bulgaria, all Tribulus is not created equal. Studies that were conducted at the University of Mississippi conclusively proved that Bulgarian Tribulus included significantly more steroidal saponins than plants found in other areas that the plant grows. In particular, the steroidal saponin called Protodioscin, which is considered to be the most important compound in the botanical, is found in measurable levels only in Bulgaria. The aerial portion of the plant including the fruit contains pharmacologically active metabolites such as phytosteroids, flavonoids, alkaloids and glycosides. However it is the Protodioscin as well as other steroidal saponins that are believed to actually elevate the level of several hormones in the human body. Clinical studies in the past using Bulgarian Tribulus revealed that herbal extracts of the material elevated levels of LH (Luteinizing Hormone), FSH (Follicle Stimulating Hormone) and Estradiol.As the levels of these hormones is increased so too is Testosterone, sperm production and libido and well as positive changes in cholesterol, mood, and self-confidence. Individuals reported subjective feedback of increased libido and overall well-being on the product. Further, no adverse effects were reported either through the blood tests or the individuals related to liver functions or any other side effects.Tribulus terrestris has been shown to exhibit sexual enhancement properties similar to DHEA.21 One study of rabbits showed that the active protodioscin exhibited erectile activity

Panax Ginseng Root

Panax has traditionally been used internally for illnesses associated with old age or lack of appetite, insomnia, stress, shock and chronic illness. Ginseng contains phytochemicals that may support endurance and stamina. Panax Ginseng Extract also has a reputation as an aphrodisiac. Researchers note the herb stimulates the central nervous system. . It has been shown to promote spermatogenesis in men. A study published in the journal British Pharmacology, May 1995, concluded that substances in ginseng extract known as ginsenosides work in a similar way as Viagra in enhancing the effects of nitric oxide, which helps relax artery walls, allowing more blood flow into the penis. Ginseng is the source of a stimulant and supposed aphrodisiac, which is extracted from the roots Panax, commonly referred to as ginseng, is a genus of perennial herbs in the Araliaceae (ginseng family). Three species in this genus include Panax quinquefolium, Panax notaginseng, and Panax ginseng. Panax quinquefolium (American or white ginseng) is commonly found in rich woods from Maine to Georgia and from Oklahoma to Minnesota (Foster, 1990). Panax ginseng (Chinese or red ginseng) has been cultivated for thousands of years throughout China, Korea, and Japan (Anon., 1997). The botanical name Panax is derived from the Greek word for panacea. Ginseng literally means "root of man," because the root of this plant often resembles the shape of a human body (Mindell 1992). The root of Panax species is used medicinally. It takes four to five years before the root has matured enough so that it becomes medically active and worth harvesting. Cultivated varieties deteriorate badly after growing about ten years, whereas the wild root improves with age. Therefore, it is the wild root that is preferred over the cultivated varieties (Anon., 1997).

Guarana Seed Extract

Guarana is a plant that contains a natural source of caffeine.20 Caffeine is a stimulant that temporarily increases alertness, heart rate and blood flow. Fights fatigue and promotes mental alertness. Guarana is a climbing shrub native to South America, especially Brazil and Uruguay. Guarana has been used for centuries by the Amazon Indians for it's spirited and refreshing qualities. Today Brazilian miners drink Guarana beverage because it provides a wonderfully natural energetic feeling. Guarana is a potent South American energy food with numerous health benefits. For thousands of years, native Amazonians have used the seed of the guarana berry to help maintain stamina and physical endurance

Ashwagandha Root
(Red Ginseng)

The health applications for ashwagandha in traditional Indian and Ayurvedic medicine are extensive. Of particular note is its use against tumors, inflammation (including arthritis), and a wide range of infectious diseases. The shoots and seeds are also used as food and to thicken milk in India. Traditional uses of ashwagandha among tribal peoples in Africa include fevers and inflammatory conditions. Ashwagandha is frequently a constituent of Ayurvedic formulas, including a relatively common one known as shilajit.
Active constituents: The constituents believed to be active in ashwagandha have been extensively studied. Compounds known as withanolides are believed to account for the multiple medicinal applications of ashwagandha. These molecules are steroidal and bear a resemblance, both in their action and appearance, to the active constituents of Asian ginseng (Panax ginseng) known as ginsenosides. Indeed, ashwagandha has been called "Indian ginseng" by some. Ashwagandha and its withanolides have been extensively researched in a variety of animal studies examining effects on immune function, inflammation, and even cancer. Ashwagandha stimulates the activation of immune system cells, such as lymphocytes. It has also been shown to inhibit inflammation and improve memory in animal experiments. Taken together, these actions may support the traditional reputation of ashwagandha as a tonic or adaptogen -an herb with multiple, nonspecific actions that counteract the effects of stress and generally promote wellness. Ashwagandha is the dried root of a bush in the nightshade family called Withania somnifera. Also known as winter cherry or "Indian Ginseng," ashwagandha belongs to the pepper family. has many qualities. It functions as an energy booster and benefits those with slow circulation. Those who complain of tiredness, lethargy and mental sluggishness have seen positive results from Red Ginseng. It is also known for it's immune boosting properties against infection and disease. Red Ginseng promotes the secretion of sexual hormones in men and women and promotes blood production, hence penis enhancement. Chemical constituents known as "ginsenosides" have been shown to actually slow down the aging process. They do this by destroying free radicals that attack normal cells. This aspect to Red Ginseng was discovered by Dr John Walker, for which he was awarded the Nobel Prize. Further research has shown a mild decrease in systolic and diastolic blood pressure for hypertensive patients who took Red Ginseng daily. Other beneficial effects from Red Ginseng include; lowering the risk of stroke; lowering blood sugar (protection against diabetes); protection of the heart; lower bad cholesterol; help mental fatigue; elevate sexual desire and responsiveness, and penis enhancement.

L-Arginine

L-Arginine is one of the twenty amino acids that are considered essential for human life. Many studies have shown the body uses Arginine as a precursor for nitric oxide, a neurotransmitter used by the body for initiating and mediating penile erections. L-arginine is also used by the body in conjunction with ornithine, another amino acid, to produce many of the bodies' hormones. The body also utilizes Arginine to produce sperm. Arginine is an amino acid that helps form nitric oxide, a chemical messenger involved in dilating blood vessels.

Damiana Leaf Extract

Damiana has an ancient reputation as an aphrodisiac. In traditional medicine it has been used for thousands of years and is indicated for use as a preventative for disease and sexual dysfunction. In the 1900s, a doctor in the US who conducted research in his own practice found Damiana to assist in cases of partial impotence and sexual debility. And in Europe the herb is deemed not only to enhance sexual ability, but to also have an excellent effect on the reproductive organs. Experts believe it aids sexual function by mildly irritating the urethra. The urethra is the passageway for urine, and in men it also acts as a genital duct that carries sperm to the exterior. It is hypothesized that this slight irritation increases the sensitivity of the penis. The leaves contain beta-sitosterol and other aromatic oils. These constituents may be responsible for the stimulant effect and the building of the sexual and reproductive systems. It is also used for chronic fatigue and mental and physical exhaustion. Damiana affects primarily the urinary and reproductive systems. It has been used as an aphrodisiac and to boost sexual potency in men by the native peoples of Mexico, including the Mayan Indians, for thousands of years. It is said to act as a sexual stimulant and produce a feeling of general well being. Damiana is sometimes used in men to treat spermatorrhea, premature ejaculation, sexual sluggishness, and prostate complaints. It is often used in combination with other herbs to treat impotence. Damiana, of the Turneraceae plant family, is an aromatic shrub with small yellow flowers that grows on dry, sunny, rocky hillsides in south Texas, Southern California, Mexico, and Central America. The two species used in herbal healing, both of which are referred to as damiana, are Turnera aphrodisiaca and Turnera diffusa. Damiana usually grows to a height of about 24 in (60 cm). Its pale green leaves, which turn yellow-brown when dried, are 0.5-1 in (15-25 mm) long and quite narrow. They have serrated (jagged) edges. The leaves and sometimes the stems of the plant have medicinal uses. Other names for damiana include old woman's broom, Mexican damiana, pastorata, hierba del venado, oreganello, and the bourrique. It had long enjoyed a local reputation as a stimulant tonic of the sexual apparatus among the natives of Mexico,

Gingko Biloba Leaf Extract

Traceable back 300 million years, the ginkgo is the oldest surviving species of tree. Although it died out in Europe during the Ice Age, ginkgo survived in China, Japan, and other parts of East Asia. It has been cultivated extensively for both ceremonial and medical purposes, and some particularly revered trees have been lovingly tended for over 1,000 years. Presently, ginkgo is the most widely prescribed herb in Germany, reaching a total prescription count of over 6 million in 1995. Numerous studies have found that ginkgo extracts can improve circulation. The herb appears to make the blood more fluid, reduce the tendency toward blood clots, extend the life of a natural blood vessel-relaxing substance, and act as an antioxidant. Recent reports suggest that ginkgo may also be useful in reversing the impotence caused by drugs in the Prozac family as well as other types of antidepressant medications. Ginkgo is a popular herb that has been used traditionally for thousands of years, and recently for its reported effects for memory, brain and heart benefits. The actives in Ginkgo work to dilate blood vessels giving more blood to the extremities.28,29 These actives also improve elasticity to blood vessels, allowing more blood to flow through the body being a reliable peripheral vasodilator, Ginkgo has been shown to be an excellent agent for treating arterial erectile dysfunction. It has a direct effect on endothelial cells which enhance blood flow of both penile arteries for penis enhancement and veins without any change in systemic blood pressure. An abundance of research has been undertaken on this ancient plant, revealing a wide range of profound and important therapeutic effects. Gingko is believed to increase stamina and longevity and has been called `The Fountain of Youth'. Ginkgo not only helps brain circulation but also penile blood flow. A study using a standardized extract showed 78% in regained erections which where known to be caused by poor blood flow.

Saw Palmetto

Saw Palmetto has a diverse use, toxifying the reproductive system, moving phlegm out of the body, and adding strength or yang energy. It is considered an aphrodisiac penis enhancement. It treats wasting diseases (such as diabetes), impotence, frigidity, dysmenorrhea, sexual neurasthenia, and prostate problems. Saw Palmetto is used to treat benign prostatic hyperplasia (BPH), an enlargement of the prostate gland that affects about half of all men older than fifty. BPH is a non-cancerous growth of the prostate gland. If the prostate grows in mature men, it pinches the urethra, or urine tube, and problems begin, including painful urination and frequent nighttime trips to the bathroom. The average male over age 50 may suffer from a variety of reproductive ailments, such as prostate problems, low back pain, and diminishing sexual vitality-this herb can help in alleviating some, if not all, of these symptoms. It helps the body build muscles, and is good for colds, asthma, bronchitis and catarrh due to hypo-functioning and coldness in the body. Saw palmetto is a small shrubby palm native to Florida and has a long folk history as an aphrodisiac and sexual rejuvenator. The berries were used by the American Indians as a general tonic to nourish the body and encourage appetite and normal weight gain. Recent studies have implicated saw palmetto as an effective treatment for benign prostatic hyperplasia. Investigators have found that the fat and sterol extracts (fatty acids: capric, caprylic, caproic, lauric, palmitic, and oleic; sterols: beta-sistosterol, stimasterol, cycloartenol, stimasterol, luepol, lupenone and 24-methyl-cycloartenol) are the active ingredients responsible for its therapeutic action. Both appear to inhibit testosterone-5-alpha-reductase, an enzyme that converts testosterone to dihydrotestosterone (DHT). Dihydrotestosterone is linked to increased cell proliferation and subsequent enlargement of the prostate. In addition, saw palmetto inhibits the binding of DHT to receptors thus blocking its action and promoting the breakdown of this component. Various human studies have illustrated saw palmetto's efficacy in ameliorating prostate enlargement with the added benefit of minor, if any, side effects

Muira Puama Stem Extract

Muira Puama is a safe and more effective alternative for penis enhancement to Yohimbe extract or capsules. Recent clinical research reported that Muira puama was more effective than the prescription drug, yohimbine hydrochloride, for loss of libido in 64% of 362 men studied without side effects An aphrodisiac regularly used by sexually healthy men and women for it's ability to enhance and prolong the sexual experience Muira puama has been used traditionally for thousands of years as an aphrodisiac. Many have touted it for its uses in improving sexual arousal, desire and helping with impotence. Current research shows favorable results using Muira puama for various sexual problems Muira puama, marapuama or liriosma is a bush occurring in the northern and northeastern parts of Brazil. The white flowers have a jasmine-like pungent and aromatic smell. It is also known under the name potency wood or under its latin name Ptychopetalum uncinatum (also known as P. olacoides) The active constituents are contained in the bark from which a concentrated water extract or a dilute herbal tea can be prepared. The herbal tea is slightly bitter but can, of course, be sweetened to make it more palatable. A daily dose of muira puama would correspond to the order of magnitude of one gramme of bark. It is alleged to be effective against a multitude of symptoms. M. Penna in "Notes Sobre Plantas Brasileires" (1930) includes treatment of disorders of the nervous system, impotency, and gastrointestinal and circulatory astenia. D. Schwontkowski in "Herbs of the Amazon" (1993) mentiones not only impotence but frigidity, menstrual cramps and premenstrual syndrome. In a French study of 262 patients complaining of erectile impotence or lack of libido, within two weeks of daily treatment 62 % of patients with loss of libido claimed that the treatment had effect. Of the patients with erection failures 51 % felt that muira puama was beneficial. No constituents, which could give rise to the reported alleged effects have yet been isolated and identified. Muira Puama is traditionally used as an aphrodisiac. South American Indians sometimes drink a muira puama beverage before planned lovemaking to enhance sexual desire. Muira puama is also a traditional herb for nervous exhaustion and depression. A paper presented at The First International Congress on Ethnopharmacology held in Strasbourg, France, in 1990, described a trial done at the Institute of Sexology in Paris on 262 men with erection problems and a lack of sexual desire. Researchers found that over half of the subjects given a daily dose of 1 to 1.5 g of muira puama extract over two weeks experienced positive benefits to their sex lives.

Maca

Maca Maca is a nut found in South America that has been used for thousands of years for energy and as an aphrodisiac. Recent research has found it to increase sexual activity in rat subjects For centuries, the Maca root has grown wild in the Peruvian Andes just below the glacial icecap. The only area where this particular species of maca is found is a region of extreme weather conditions such as freezing, high winds, and intensive sunlight. No other food plant exists in the world which will grow at so high an altitude and survive. Native shepherds soon learned that as they grazed their herds in higher elevations, where Maca grows naturally, the herds became healthier, with more stamina and became much more sexually active. Soon, the Andean Herd People included Maca in their diets, and found Maca could help promote increased energy and stamina for themselves.
The rich soil located at these high plateaus of Peru where it is very cold and oxygen poor may account for the high levels of trace minerals found in maca root. Some Peruvian Indians of today still grow it in the same traditional way without pesticides or chemicals. The healing qualities of maca have helped the local native population thrive in this oxygen-poor plateau where they live. Maca root contains significant amounts of amino acids, complex carbohydrates, vitamins B1, B2, B12, C and E and minerals, including calcium, phosphorus, zinc, magnesium and iron. This herb has been traditionally used as an aphrodisiac for both men and women, to increase energy, vitality, stamina and endurance in athletes, promote mental clarity, for fertility and to increase male seminal fluid volume, sperm count and sperm motility, for treating male impotence and erectile dysfunction, and for female menstrual irregularities and hormone imbalances, including menopause and perimenopause. Women with menstrual irregularities have experienced greater consistency, while women with hot flashes, mood swings and most associated perimenopause and menopause symptoms have diminished dramatically. Due to the number of steroidal glycosides present in Maca root it is gaining popularity among weight lifters and body builders as a natural alternative to anabolic steroids.The popularity of maca worldwide is growing at an enormous rate.. In August of 2001, results of the first major clinical trial conducted on the effects of maca consumption were released. The maca used in the study was a very concentrated, powerful version created through a process called gelatinization.

Epimedium Sagitatum (Horny Goat Weed)

Epimedium Sagitatum otherwise known as Horny Goat Weed) penis enhancement herb is a Chinese herb often referred to as a "Yang tonic". This herb produces a warm, almost euphoric effect on the body. Epimedium is commonly used as an aphrodisiac penis enhancement and aids in relieving sexual dysfunction. Epimedium herb stimulates the production of androgens (sex hormones) and has been used successfully in men suffering from impotence and a low sperm count. Studies have shown that epimedium raises adrenaline, noradrenaline, serotonin, and dopamine levels in animals. It is the dopamine that may be responsible for the herb's use as a reproductive tonic. The increased dopamine levels in the body set off a chain reaction that leads to a release of testosterone, the male sex hormone. Other evidence suggests the herb increases sensitivity in nerve endings, which may explain why it is prescribed as an aphrodisiac. Horny Goat Weed (Epimedium grandiflorum, Epimedium sagittatum) is a plant species popular in China, Korea, and Japan as an aphrodisiac and sexual rejuvenator. The first recorded use of the plant dates back to 200 BC in China. Supposedly, the plant is responsible for many sexually enhancing effects. Epimedium contains the flavonoid lcariin that allegedly stimulates sensory nerves, particularly in the genitals. It has been shown that Epimedium does increase sexual activity and semen production in animals. It has an androgenic-like effect on male genitals, increasing sperm production, copulation activity, and testosterone levels.(1) Testosterone stimulates centers of the brain having to do with increased sexual desire in both men and women. Although there is limited scientific data available to substantiate the claims of epimedium, studies were conducted that demonstrated that epimedium sagittatum does improve sexuality and quality of life in patients undergoing hemodialysis for renal failure.

Avena Sativa (Wild Oats)

Avena Sativa (Wild Oats) is a botanical extract that has traditionally been used to increase strength, mind, spirit and body. References to the sexually stimulating effects of oats have been found up to 200 years ago in the German Pharmacopoeia. Modern studies at the Institute For Advanced Study of Human Sexuality have shown that Avena Sativa helps improve interest in sex. Researchers discovered that Avena Sativa works by freeing up testosterone, which becomes increasingly bound to various compounds within the body with advancing age. Bound testosterone is not nearly as effective as free testosterone in stimulating the sex centres in the brain that generate the sex drive that leads us to seek out and engage in sexual activity. The first reference to the sexual enhancement properties of wild oats (avena sativa) can be found in the German Pharmacopoeia of the late eighteenth centruy. Subsequent research has revealed that wild oats (avena sativa) free bound testosterone and oppose the action of sex hormone binding globulin. Significant positive effects of avena sativa have been measured in both men and women. About seventy percent of men and women report increased energy, feelings of well-being and sexual desire through the use of avena sativa. These results are correlated with increased serum levels of free testosterone. These findings support many cultural references in language that refer to the health benefits of wild oats. Common expressions such as "feeling his oats" and "sowing his wild oats" attest to the well known traditionally understood effects of strength, vigor, and sexuality.of the wild oat (avena sativa) From 1986 to 1988 the Institute for Advanced Study of Human Sexuality conducted case studies and clinical trials on the effect of Avena Sativa extract on men and women. Trials were done on individuals who had consulted sexual health care professional help. Subjects were administered avena sativa extract either daily or episodically. The results were mixed with about seventy percent of men and women experiencing significant improvement in sexual desire, response and functional performance. Amoung the remaining thirty percent, some experienced moderate improvement while others remained unchanged. Upon subsequent analyisis it became evident that participants with significant positive respone, had initial low serum levels of bound testosterone.
Later the institute conducted a study to determine optimal doseage levels. The study tested the effects of high and lower doses of avena sativa extract on men diagnosed as impotent (erectile dysfunction) by a team of urologists. Men who did not experience positive response using 300 mg per day after 30 days were administered 600 mg per day for 30 days. The results showed a marked improvement with the higher doses for men who had no effect in the original lower dose study. Men in the study reported no negative side effects related to the use of avena sativa. Some women reported some side effects of irritability but with positive sexual respones. Many men and women in the studies did report significant increases in energy and sense of well-being beyond the positive sexual enhancement. Later studies revealed significant improvements in sexual desire and response for women with avena sativa extract mixed with saw palmetto.
