What is Eurycoma Longifolia?

Eurycoma 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 used for treating erectile dysfunction (ED), increasing interest in sex, male infertility, boosting athletic performance, body building, and reducing body fat. Eurycoma longifolia is also used for fever, malaria, ulcers, high blood pressure, tuberculosis, bone pain, cough, diarrhea, headache, syphilis, and cancer.
