Overview InformationEurycoma longifolia is a tall, slender evergreen shrub-tree commonly found in Southeast Asia. Malaysian men claim that tea made from this plant improves their sexual abilities and virility. As a result, this plant is in such high demand that it is now considered a “protected” species.
The root and bark of Eurycoma longifolia are commonly used orally for treating erectile dysfunction, increasing sexual desire, treating male infertility, and boosting athletic performance. Some research supports the use of Eurycoma longifolia for sexual desire and male infertility. But there is limited scientific evidence to support its other uses.
How does it work?The root of Eurycoma longifolia contains several chemicals that have different effects in the body. Some of the chemicals seem to affect how the body produces the hormone testosterone. Research in animals and humans suggests it might increase testosterone in the body.
Uses & Effectiveness
Possibly Effective for
- Male Infertility. Some clinical research suggests that taking Eurycoma longifolia supplements by mouth can improve the quality and concentration of sperm in infertile men.
- Sexual desire. Some clinical research suggests taking Eurycoma longifolia supplements by mouth improves sexual desire and quality of life in healthy married men.
Possibly Ineffective for
- Athletic performance. Some research shows that taking Eurycoma longifolia does not help male athletes run farther or improve overall physical fitness.
Insufficient Evidence for
- Problems achieving an erection (erectile dysfunction, ED). Eurycoma longifolia extract might be helpful in men with erectile dysfunction. However, it is not clear if it helps erectile function in healthy men. Also, it is possible that Eurycoma longifolia only helps when it is taken with another herb called Persicaria minor. Scientists need to do more research to see who can benefit from Eurycoma longifolia.
- Low testosterone. Early research shows that taking an extract of Eurycoma longifolia by mouth for one month might increase testosterone levels and improve related symptoms in men with low testosterone levels.
- Muscle strength. Early research suggests that taking Eurycoma longifolia by mouth for 5 weeks helps increase muscle mass and strength in healthy men participating in an intense strength training program.
- Increasing interest in sex.
- Low back pain.
- High blood pressure.
- Bone pain.
- Other conditions.
Side Effects & SafetyEurycoma longifolia is POSSIBLY SAFE when taken by mouth in medicinal amounts for up to 9 months. Eurycoma longifolia is POSSIBLY UNSAFE when used orally in large amounts. Some Eurycoma longifolia supplements from Malaysia have been found to contain mercury or lead. A drug used to treat erectile dysfunction known as sildenafil (Viagra) has also been found in some Eurycoma longifolia supplements. Taking too much Eurycoma longifolia might cause mercury or lead poisoning or other side effects.
Special Precautions & Warnings:Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking Eurycoma longifolia if you are pregnant or breast-feeding. Stay on the safe side and avoid use.
