Tongkat Ali: The Science Behind An Old Wives’ Tale

The question arises whether Tongkat Ali’s reputation is merely an old wives’ tale, fueled by its sexual potency ability, or can it be subjected to scientific trials and still emerge a substantiated remedy?
Research into this herb began in the eighties, and early studies showed that it increased libido and sexual arousal in laboratory animals. These initial results spurred further research, including a collaboration between the Massachusetts Institute of Technology, USA and various research institutions in Malaysia. The result was a patented Tongkat Ali extract, produced from freeze drying the water extract of the root, which was found to increase the levels of testosterone and improve reproductive health. Male test animals were found to produce sperms of better quality and higher quantity. Zooming into the cellular level, the extract appeared to affect smooth muscle tissue relaxation, hence widening blood vessel walls and increasing blood flow.

The encouraging results motivated Dr Ismail to further prescribe Tongkat Ali for men whose causes of infertility were unable to be determined. The result was sperm production of higher concentration and better morphology, ie. size and shape, allowing aspiring parents to continue exploring natural conception or less invasive and less expensive infertility treatments. An encouraging number of these patients eventually became fathers.**
The research on Tongkat Ali continued and generated great interest among scientists. In a large clinical trial conducted by the Hospital University of Science Malaysia, a group of male test subjects was prescribed Tongkat Ali water extract and a second group was given a placebo. The group that consumed the Tongkat Ali began experiencing better quality of life compared to the placebo group. They reported enjoying enhanced vitality and libido, and were tested to show marked improvements in the quality and quantity of sperm production. These health improvements, however, would be redundant if the male is affected by erectile dysfunction. Fortunately, researchers in the US discovered that by supplementing diets of male test subjects with freeze dried Tongkat Ali water extract, their mild erectile dysfunction symptoms were alleviated and a wide range of other health indications were boosted.
Besides its aphrodisiacal effects, Tongkat Ali has been examined for its ability to increase muscle strength and size, specifically during intensive strength training. In a US study, competitive cyclists were found to recover quicker from fatigue. According to Dr Shawn Talbott, a nutritionist with Supplement Watch USA and one of America’s leading lifestyle expert, the Tongkat Ali extract work by lowering cortisol and increasing testosterone levels, an optimal condition that encourages the recovery process. Other side effects include greater muscle strength and leaner mass compared to test subjects on placebo.
Testosterone levels in men deplete at a rate of 1% every year, after the age of 30. As a result, men endure decreasing muscle tone and bone density, and increasing risk of osteoporosis as they age. In another study of male lab rats with their testicles removed, a combination of therapy that includes Tongkat Ali successfully reduced bone turnover and improved its strength.
