What is Tongkat Ali in English or in other language?

Tongkat Ali in English is known as Longjack. In fact, it is one of the few herbs which has multiple household names in different languages, depending on which country you live in.

Tongkat Ali is also commonly known as ‘Pasak Bumi’ in Indonesia, Cay Ba Binh in Vietnam, Pin Yin: 东革阿里 or Dōng gé ālǐ in China, ‘Longjack’ in United States or Europe and ‘Malaysian Ginseng’ or `Akar Ali’ by some locals.  Interestingly the Russians and Arabs refer to it as “Tongat Ali”.

The word “Tongkat Ali” root comes from a direct translation from the Malay language that means Ali’s root. It is also common for locals to refer Tongkat Ali as Akar Ali, and easily pronounced as aka-rali in short.

What is Eurycoma Longifolia?

Eurycoma Longifolia is the scientific name of the Tongkat Ali plant. 

This plant is often referred to as Eurycoma Longifolia in research studies and amongst the scientist’s community, but it is not used or referred to widely amongst general consumers.

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.

What is the difference between boiling Tongkat Ali root and drink as a herbal tea vs. consuming in capsule form?

The key difference is the effectiveness to your body (and health). 

The boiling method is a traditional method used for centuries. By boiling, you extract all the good, the bad and the ugly ingredients which are not visible to your naked eye. This in the long term, can be detrimental to your health (and kidneys) due to unwanted bio-active compounds that are absorbed into your body. Besides that, the boiling approach can accidentally destroy the best nutrients from Tongkat Ali. 

AKARALI™ capsules contain pure Tongkat Ali powder which is produced through a patented extraction process known as Physta®. This process uses freeze-dried approach where only the best nutrients are extracted to deliver the best that your body deserves. In short, it delivers the highest potency with a higher rate of absorption into your cells.

The difference can be felt instantly when comparing between these two methods. 

Can you consume Tongkat Ali with coffee?

Yes, you can. There are more than 100 Tongkat Ali coffee brands sold in the market today and most of it are in pre-mixed 3-in-1 instant coffee packets.  

Unfortunately, the common 3-in-1 Tongkat Ali coffee brands do not deliver the best taste, nor the best health benefits as it contains more processed sugar than coffee or Tongkat Ali extract.

Now, since Tongkat Ali is also available in capsule form, you can make your own Tongkat Ali coffee with these following simple steps:

  1. In a small saucepan, combine the coffee, milk, honey and Tongkat Ali (200 mg extract from 1 capsule)
  2. Cook and stir with low heat for 5 minutes. (Please do not let it boil.)
  3. Remove from the heat; stir in vanilla.
  4. Pour into cups or mugs and serve immediately.


With the right dosage, you can tailor-made your Tongkat Ali coffee to suit your taste and health objectives.


What does it feel like after consuming Tongkat Ali?

In the first hour after your first dosage, you will feel more mentally awake with greater clarity as your neurotransmitters are being produced in your brain (e.g.: dopamine, a feel-good hormone). Some reported increased in sexual desire with improved mood and reduction in anxiety.

After about two weeks of consumption, Tongkat Ali begins to have an effect on the endocrine system by increasing (freeing up more) testosterone levels and decreasing the stress hormone known as cortisol.

What happens if I stop consuming Tongkat Ali?

Once you stop consuming Tongkat Ali temporarily or for good, you will not experience any withdrawal symptoms or side-effects.

So during the “OFF” cycle, you can stop consuming Tongkat Ali temporarily without any drop in strength or energy level. Nor it has any downside to your sexual health or libido.

However, if you are a serious bodybuilder or in sports competition and decide to stop consuming Tongkat Ali, you may notice a sudden or a gradual drop in performance – either in energy conservation, utilization or strength. This is because your body is more sensitive to any changes in nutrients during the workout or training.
