Knowledge: Tongkat Ali (Eurycoma longifolia)

Tongkat Ali Long Jack (Eurycoma Longifolia)

Tongkat Ali also known as Eurycoma longifolia and is called Longjack in America, is an evergreen small tree that is known to produce a wide range of positive effects, especially to men. The herb typically grows in countries within South-East Asia such as Malaysia, Thailand and Indonesia. It is mainly due to the presence of eurycomanone in Tongkat Ali (a type of quassinoid) that makes it a marker for the identification of this plant and the level of Tongkat Ali in a product.

In the past, the roots of the Tongkat Ali tree is usually the part that is ground into powder, but direct consuming provides little or no benefits plus plant cellulose is indigestible. Therefore, technology to extract the active compounds by hot water has been used to obtain the water soluble active ingredients ie. Eurycomanone, polysaccharides, proteins and glycosaponin from the herb. Subsequently, spray drying has been employed to produce Tongkat Ali extract powder which can be made used for various applications such as additives and supplements. Because the expensiveness and preciousness of the herb, studies have been moving towards the direction of increasing the amount of active compounds extracted and the yield of final product.

What is Tongkat Ali?

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 Asian countries such as Malaysia, Indonesia, and Vietnam. Some species of the plant also grow in regions of Cambodia, Myanmar, and Thailand.

Tongkat ali literally means “Ali’s walking stick,” which makes reference to its aphrodisiac effects. Some people say that the “stick” refers to the plant’s long, twisted roots that some groups harvest for their medicinal value.

Frequently Ask Questions:

What Is Eurycomanone Standardized Tongkat Ali Root Extract?
There are two forms of tongkat ali root extract available on the market today, traditional and standardized, traditional extract is strength rated by the amount of root used to produce a single gram of extract, this method of production is highly inefficient, allowing for a large margin of error in actual finished extract strength. This is because the active ingredients in a tongkat ali root extract will vary depending on the age and quality of the root used to produce the extract, rather than simply the amount of root used. An example of this would be as follows: If two separate batches of tongkat ali root extract were produced each using 50 grams of root to produce 1 gram of finished extract (1:50), the first batch using eurycomanone rich root while the second used roots with a low eurycomanone content, the two finished extracts would be completely different in strength, although each batch used 50 grams of root per 1 gram of finished extract.

How Is Standardized Tongkat Ali Root Extract Produced?
Standardized tongkat Ali root extract is produced in much the same way as traditional tongkat ali root extract, but rather than basing the strength rating on the amount of root used regardless of quality, we engage FRIM (Forest Research Institute of Malaysia) as Thrid Party Verification, who use analytic equipment in the form of ultra-high-pressure liquid chromatography tandem mass spectrometry to monitor the levels of several key active ingredients, primarily the eurycomanone content of the extract.

What Are The Benefits Of Standardized Extract?
Besides the obvious benefits of safety and quality through consistency, using analytic equipment to produce plant extracts stops the unnecessary waste of raw materials by adjusting the formula at a granular level. Additionally this method of production helps to reduce fraudulent activity in the supply chain, as the process is completely verifiable from start to finish.

Does Tongkat Ali really work?
Tongkat Ali works on several mechanisms involved with hormonal function and Intimacy performance. In other words, Tongkat Ali minimish ageing on the men reproductive system by increasing body’s free testosterone bio-availability.

  1. Stimulating the Leydig cells of your testicles to produce testosterone .
  2. Reducing the conversion of Testosterone to Estrogen
  3. Decrease in hormone binding globulin
  4. Reduce stress hormone


Estrogen levels of the average 54-year-old man are often higher than those of the average 59-year-old woman. Too much estrogen contributes to a wide range of health, weight gain and libido problems. High serum levels of estrogen also trick the brain into thinking that enough testosterone is being produced, thereby slowing the natural production of testosterone. Results of studies have confirmed Tongkat Ali may be of assistance in the following areas:

  • Create free testosterone level
  • Improving erectile strength without side effects
  • Increase in men fertility, sperm quality, motility and quantity
  • Natural energy booster
  • Improving strength during exercise with an anabolic effect on muscle growth
  • Decrease in hormone binding globulin (SHBG)
  • May promote weight loss


Can I take Tongkat Ali if I have high blood pressure?
Tongkat Ali will not aggravate high blood pressure as it has a mild anti-hypertensive vasodilatory effect. One of the reasons Tongkat Ali is beneficial for erectile dysfunction is because it assists vasodilation of penile circulation as confirmed in scientific research.

What recommended dosage for Tongkat Ali Root Extract?
Tongkat Ali dosage increases with age and is also based on the underlying hormonal deficiency. As such, the dosage of a 65 years old will need to be increased from that of a 35 year old. Taking this into consideration you may experiment to find the dosage that feels right for you.

Does Tongkat Ali have any side effects?
Our Tongkat Ali products, taken at their recommended dosage are very well tolerated and free of toxicity. One may experience an increase in metabolic body heat (thermogenesis) after taking Tongkat Ali and it is recommended to increase water intake. For individuals with high blood pressure and or diabetes then our Rainforest Herbs Tongkat Ali Plus Capsules formulation has been specially prepared to support male hormonal and cardiovascular health and antioxidant protection from free radical damage. In my experience each individual reacts slightly differently, so the product dosage that works for you may be different for another. High dosages may give more dramatic effects on libido within a shorter time frame of around 1-2 days, while lower dosages may take 1 week or more to notice the effect.

What is Red and Black Tongkat Ali?
Yellow, Red and Black Tongkat Ali are all unrelated medicinal plants that share a similar common name in some regions of Malaysia. However, the name Tongkat Ali is most commonly in reference to yellow Tongkat Ali (yellow) or Eurycoma longifolia, of the family:Simaroubaceae.

Can Tongkat Ali be taken by women?
Yes, Women in Borneo take Tongkat Ali as Energy Booster. Tongkat Ali is suitable in menopausal women as it helps maintain progesterone production from the ovaries and adrenal glands.

Is Tongkat Ali high in Heavy Metal?
Tongkat Ali are harvested in rain forest, thus the heavy metal have negligible levels. All root herb or vegetables must be thoroughly cleansed of surface soil after collection. All batches of health products manufactured under GMP & HACCP standards must undergo a heavy metal test (Atomic Absorption Spectrometry) to determine whether lead and other heavy metals are present.

How to maximize the effects of Tongkat Ali ?
Reduce Carbohydrate Intake and Regular exercise / workouts can improve the results and accelerate muscle growth and increase testosterone production and enhance libido.

What Is Eurycomanone And Why Is It So Important?
Eurycomanone is the active compound found in the root of the eurycoma longifolia plant, more widely known as tongkat ali. Studies have shown that eurycomanone increases the amount of free testosterone available in the bloodstream by inhibiting the conversion of testosterone to estrogen, this causes an increase of testo to build up over a period of time. At higher concentrations, eurycomanone also acts as a phosphodiesterase type 5 inhibitor and is currently being studied for the treatment of erectile dysfunction.

What Strength of Eurycomanone Standardized Tongkat Ali Root Extract is Best?
Eurycomanone is available in pure form, but this is not safe to consume and certainly would not be considered a tongkat ali root extract for therapeutic use. For safe human consumption standardized tongkat ali root extract starts at 0.5% eurycomanone and the upper limits are around 2.7% eurycomanone, in these strengths standardized tongkat ali root extract is used as a safe testo booster with the higher strength extracts also acting as a PDE5 inhibitor.
