Eurycoma Longifolia; The Wonder Herb and Sexual Stimulant

Eurycoma Longifolia has been widely used in Asia for centuries as a cure for erectile dysfunctions and low libido.

Eurycoma has also been shown to elevate the energy system and increase an individuals metabolic rate and enhance blood circulation. These factors contribute to the heat-generating characteristic (thermogenic) of Eurycoma.


Sexual Stimulant

Eurycoma incites the testes to produce more testosterone on their own by sending signal to the hypothalamus and the pituitary glands, and not by supplying exogenous testosterone.

Synthetic testosterone (anabolic steroids) can supplement your body with testosterone, but steroids interfere awkwardly with male sexuality, causing penile and testicular shrinkage.When testosterone levels are elevated, the sex hormones (androgens and estrogens) will signal your body to decrease or stop its own testosterone production, this is call "negative feedback". 

Eurycoma intercepts the negative feedback to the hypothalamus and pituitary gland, which results in the body to continuing to produce testosterone at elevated levels. Because the testes are in full testosterone production mode, the penis and testicles will increase in size. Studies have shown Eurycoma Longifolia to be a potent sexual stimulant.

Increasing Levels of Testosterone

In one study, a product containing Eurycoma was found capable of markedly improving testosterone production in men. In a test with 11 male subjects with hypogonadism, the average testosterone increase after 1 month of regular consumption of the product was 50%.

Initial studies at higher doses on both hypogonadal and healthy male subjects show increased testosterone boosting ability. In human studies, analysis of the DHEA showed gradual increase in the level from 26% after 1 week to 47% in 3 weeks. SHBG analysis showed decrease in level from 36% after 1 week to 66% after 3 weeks. Consequently, when the SHBG level declines, the Free Testosterone Index goes up in most subjects. This increase in Free Testosterone indicates that it has a bio-stimulatory effect on steroidogensis, meaning that Eurycoma has the ability to enhance testosterone biosynthesis.

Compared to other Natural Sexual Stimulants

Some years ago, traditional herbalists from several Asian countries researched three highly-rated aphrodisiac herbs - the African herb Yohimbe, Ginseng and Eurycoma Longifolia - to determine their effectiveness in the treatment of male impotence.

After exhaustive research, it was concluded that Eurycoma Longifolia was, by far, the most effective of the three. Thereby dispelling the myth that Yohimbe is the best herbal aphrodisiac in the world.

 It is also interesting to note that although Yohimbe is a proven herbal aphrodisiac that works well, medical professionls caution against the continued use of  it as it has been shown to cause very unpleasant side effects like palpitation, vomiting, insomnia, body aches and aggressive behavior. While Yohimbe is not illegal in the US, it is banned in many countries throughout the world. 

Description

Eurycoma Longifolia (Simaroubaceae) is a small tree to measuring up to 15 m in hight. Plants are dioecious (flowers on a plant are either male or female). Leaves compound, long, and crowded at the tips of the branches. When the leaves fall they leave large scars on the stems.
Leaflets are ovate-lanceolate, sessile or nearly so, and opposite. Flowers are borne in axillaries panicles, mostly large and lax and puberulous with short hairs. Flowers are unisexual; male flower has sterile pistil, female flower has sterile stamens. Fruits ellipsoid or ovoid, 10-20 x 5-12 mm, green to blackish-red when ripe.

Ecology

Eurycoma Longifolia prefers acid and sandy soils at low altitude up to 700 m above sea level. Plants usually grow in beach forests, primary and secondary forests, mixed dipterocarp forests and also in heath forests. In Riau Province, Sumatra, 1991, the author found that plants were growing in areas with an average temperature of 25C and 86% humidity. The soils in this area were found to be poor in nutrients, but mycorrhizal fungi were found growing near the plants and may indicate an association. Seedlings require shade during which time they develop an extensive root system. Following juvenile stages, plants need stronger light to develop vegetative and reproductive parts. E. Longifolia flowers and fruits throughout the year, with peak flowering from June-July and peak fruiting in September.

Distribution
 
E. Longifolia originates from South East Asia, including Indonesia, Malay Peninsula, Thailand, Laos, Cambodia and Vietnam. In Indonesia, this species only occurs naturally in Sumatra and Kalimantan.
