Eurycoma longifolia, also known as Tongkat Ali is a traditional Asian remedy for male sexual performance. It is a shrubby tree native to Southeast Asia. The plant is indigenous to Malaysia, Indonesia, and Vietnam.

Tongkat Ali, or longjack, is an herbal supplement that comes from the roots of the green shrub tree Eurycoma longifolia, which is native to Southeast Asia. 

It's used in traditional medicine in Malaysia, Indonesia, Vietnam, and other Asian countries to treat malaria, infections, fevers, male infertility, and erectile dysfunction. 

The health benefits of tongkat ali likely stem from various compounds found in the plant. 

Specificially, tongkat ali contains flavonoids, alkaloids, and other compounds that act as antioxidants. Antioxidants are compounds that fight cellular damage caused by molecules called free radicals. In traditional medicine, people use tongkat ali to relieve the following conditions: 

  • sexual dysfunction
  • malaria
  • high blood pressure
  • anxiety
  • diarrhea 
  • aging
  • itching
  • constipation
  • exercise recovery 
  • fever
  • diabetes
  • lumbago
  • indigestion
  • aches and pains 

Tongkat ali's potential to increase testosterone in men with low levels of this primary sex hormone is well known and well documented. 


Low testosterone can result from aging, chemotherapy, radiation treatments some medications, injury or infection of the testicles, and certain diseases, such as chronic alcoholism and obstructive sleep apnea. 

Effects of inadequate testosterone levels include low libido, erectile dysfunction, and in some cases, infertility. Since compounds in tongkat ali ay boost low testosterone, it could treat these issues. 

What's more, studies in both animals and humans show that taking tongkat ali stimulates sexual arousal and may improve erectile dysfunction in men. 

Finally, tongkat ali may improve sperm motility and concentration.
