Eurycoma longifolia jack 'Tongkat Ali' has been used to improve male virility and sexual prowess as part of ongoing cultural tradition.

New research demonstrates a scientific basis for its historical use due to the plant’s androgenic effects.
The androgen-boosting effects of this plant include enhanced libido and sexual activity in laboratory animals.
[20-22] Anecdotal reports have also shown a beneficial increase in male testosterone levels as well.
Because of these findings, Eurycoma longifolia has become a popular addition to male health regimens. Myricetin is a flavonoid also found in Euycoma longifolia. Myricetin works to inhibit the enzyme 5 alpha reductase, thereby preventing the conversion of testosterone to the prostate-damaging 5 hydroxytestosterone. [23-24] Myricetin is thought to have greater bioavailability than other flavonoids, making it an excellent addition to a hormone targeted prevention program.

Re-establishing testosterone levels can prove to be highly beneficial for men suffering the effects of lowered hormone levels.
Incorporating a supplement that uses the above-mentioned nutrients into a regimen for men at risk for hormone imbalance is a practical way to address this issue.

Providing these nutrients before hormone imbalance becomes completely symptomatic will afford the patient a much lower risk of suffering from low-testosterone-associated conditions. Raising testosterone levels can lead to a reversal of symptoms such as fatigue, low libido, diminished drive and motivation as well as several physical conditions including reversal of adiposity, gains in strength, improved cognitive function, improved bone health and possibly heart disease prevention.[25]

Tongkat ali Eurycoma longifolia Jack commonly has been successfully used in southeast Asia for generations to increase male virility and sexual prowess. The roots are the most valuable component and are used for the treatment of aches, persistent fever, malaria, sexual insufficiency, dysentery, glandular swelling, and as health supplements. Root extract of the plant have been administered for restoring energy and vitality, enhancing blood flow and functioning as a herbal ingredient for women after child birth.
