Better sex, more muscle… this is what tongkat ali can do for you. Provided you buy it from a legitimate source that doesn’t sell you an outright fake or grossly under-dosed product.
To avoid being cheated by an online con artist selling fake tongkat ali extract, just do a Google search for: tongkat ali scam. You may also want to avoid a product that uses stearic acid or stearates. To be sure, just do a Google search: tongkat ali stearic.
If you buy a Indonesian product, just make sure it is not connected to the indonesiaherbals scam that has been widely reported in Indonesian newspapers.
While men in Southeast Asia have traditionally been using tongkat ali to increase their virility, women in Southeast Asia have always relied on kacip fatima to keep pace with their men. On the other hand, women who want a stronger effect can also use tongkat ali, typically at half the male dosage.
Without doubt, in Southeast Asia love and sex are regarded as natural pleasure (for men and women) much more clearly, and more directly, than in Europe or North America. Here you still have matrilinear societies (such as the Minang on Sumatra), a kind of Islam (on Java) that encourages pre-marital love (though “officially” not pre-marital sex), societies where sexual relationships of older men and older women with much younger partners are socially accepted, and where sexual details until now are openly discussed in villages.
While both tongkat ali and kacip fatima both raise free testosterone, tongkat ali is the stronger of the two.
Men and women in Southeast Asia have long regarded it as an art and a science to improve their sexual function, or to bring it back to youthful levels when there has been an age-related decline.
Asians use many herbs for their sexual effects, and even herbs with rather distinct efficacies are traded openly. In Indonesia, for example, herbal mixtures such as “Galian Rapat” are sold at many cigarette booths. The name means “narrow cavity”, or, more specifically, “narrow vagina”, a condition considered conducive to sexual pleasure. A common ingredient is kacip fatima.  Other are sirih leaves. 
Whether the female primary sexual organ is in an optimal condition after the consumption of kacip fatima, and whether women experience heightened sexual pleasure by using the herbal (as they have done for hundreds of years) is a matter sufficiently important to the Malaysian government to finance interdisciplinary scientific research into kacip fatima. And the Malaysian government has a stake in the medical, pro-sexual use of tongkat ali for men as well.
As a long-term user of tongkat ali, I have considerable trust in Southeast Asian herbal medications. Even though kacip fatima is considered primarily a herb for women, and even though I am a man, I have tried it a few times and can attest to the herb’s pro-libido effects. The effect of a few leaves, boiled as a tea, is a mixture of sympathetic and parasympathetic stimuli, with the parasympathetic effects being dominant. Among the parasympathetic effects are nasal sinus stimulation resulting in a stuffed nose, as I also feel it from dopaminergic medications, and yes, increased blood flow to the groin. The primary sympathetic effect is a slightly increased heart rate.
