About Tongkat Ali


Tongkat Ali or Akar Ali (pronounced as Akarali in Malay language) is a herbal medicinal plant that grows mainly in Peninsular Malaysia, Borneo, Indonesia and in small patches in remote regions of Cambodia, Myanmar and Laos.

Tongkat Ali contains medicinal properties and is classified as a phytoandrogen plant due to its pharmacological effects on health.

Tongkat Ali is documented in the Malaysian Herbal Monograph in 2015 published by the National Pharmaceutical Regulatory Agency (NPRA) of Malaysia. 

Tongkat Ali plants are harvested in the wild rainforests by indigenous people (i.e Orang Asli), where the Tongkat Ali roots (i.e Akar Ali) are cut into smaller pieces for extraction.

Harvesting is done every three to five years to obtain mature roots that are ideal for extraction. Most Tongkat Ali harvesting in Malaysia does not cause deforestation, thus minimizing damage to the natural ecosystem.


The botanical (scientific name) of Tongkat Ali is Eurycoma Longifolia, which is formed from Greek and Latin words.

In Greek, the word “eurys” originally means broad while “come” means a tufted bush, which describes the plant’s physical attributes. The word Eurycoma refers to the growth habit of its compound leaves that spirals out at the tip of its slender trunk in a large dense rosette.

In Latin, “Longus” means long and Folia refers to the leaves, so the word Longifolia describes the compound leaflets that are often long and slender. 

Tongkat Ali is also known by other names such as ‘Pasak Bumi’ in Indonesia, Cay Ba Binh in Vietnam, Pin Yin: 东革阿里 or Dōng gé ālǐ in China, ‘Longjack’ in the United States or Europe and ‘Malaysian Ginseng’ or `Akar Ali’ by locals.


 Tongkat Ali root, or Akar Ali in the Malay language, has a rich history dating back to the 1600s before the rise of the British Empire in the 1800s. 

Tongkat Ali was first documented as a medicinal plant by William Jack, a Scottish surgeon-botanist during his visit to Malaysia in 1820.

In his book titled “Descriptions of Malayan Plants” (1820-1822) in the Malayan Miscellanies, Tongkat Ali was used by Malaysians to treat diseases and illnesses.

Subsequently, a journal on William Jack’s findings on Tongkat Ali was published by Harvard University in 1952. 

The first commercialization of Tongkat Ali took place by MIT scientists and the Malaysian Government in early 2000. This historic change marked a new milestone and changed the industry landscape, with increasing clinical trials and quality standards.

At the present time, Malaysian Tongkat Ali is highly sought after due to its quality standards.

Eurycoma longifolia or Long Jack was first discovered in Malaysia as described by explorer William Jack circa 1800s.

The original description of the Tongkat Ali species known as Eurycoma Longifolia was published in the Malayan Miscellanies, Volume 2, in 1822 . The original publication was reprinted in book titled the Description of Malayan Plants, I – III, Bencoolen 1820 – 1822, by Boerhaave Press, Leiden, in 1977.
