This includes anti-malarial, anti-bacterial, antipyretic, anti-ulcer, anti-tumor, and cytotoxic properties. Scientific research on male rats has also found that Eurycoma longifolia does increase the plasma testosterone and sperm count in these rats. Other studies have also found that it can actually enhance the sexual performance and characteristics in animals. In other studies, it has also been shown to by cytotoxic to lung cancer cells and induce apopotosis in breast cancer cells.

In studies done by the Department of Exercise Physiology at the top university in Malaysia, University of Malaya, it was found to increase muscle strength and sized when compared to a placebo. This was presented in the British Journal of Sports Medicine and will also be presented at an upcoming conference. Although alternative medicine, especially herbal medicine, is often rebuked by western medicine, the backing by this prominent journal does truly show that herbal medicine is important and not some kind of pseudo-science.

It is sold in various ratios, usually either 1:20, 1:50, 1:100, and 1:200. Traditionally, it was extracted with water and not ethanol. However, selling Tongkat Ali based on this extraction ratio is a bit confusing. As a result, professional manufacturers of these supplements are standardising this extract across the board so that it is not open to abuse.
