Historical

"It has been used in Malaysia for many years by men to increase sexual desire, libido, sexual performance and to treat erectile dysfunction."(3) In the old days, the roots, found only in the wild tropical forest of Southeast Asia, had to be brewed for long hours to get a bitter extract. Now, Tongkat Ali, which literally means Ali's cane, is widely sold in pill or "tea-bag" form and mixed with regular Coffee or tea for an extra "lift". (4)
