Tongkat Ali

is more than just for great sex. It is life-altering.

What do people think about Tongkat Ali?

Malaysians have a set perception of Tongkat Ali whenever it comes up as a topic or is seen at a local shop vendor selling Tongkat Ali Jantan Kopi (Male Tongkat Ali Coffee), people will often laugh or smirk at the idea of someone consuming it for the sake of sexual prowess. Which no one is at fault because people only understand Tongkat Ali as just a sex herb & nothing else.


And this is true. For decades, people have often overlooked Tongkat Ali, a natural & organic treasure as a thing to only "enhance" sexual desires just for men.

We want to change the narrative of Tongkat Ali is just for the libido of men, but changes our lifestyle from good, to a greater & healthier mind & body. Men & women.

What is Tongkat Ali all about?

Tongkat Ali, also known as Eurycoma Longifolia or Pasak Bumi, is a native herbal root found in all of Indochina with a figure of a slim towering plant reaching 10 meters in height.

For generations, it is mainly found in the deep conservation & protected rain forests of Malaysia. Tongkat Ali has been most commonly used as a traditional herb by the indigenous tribe of Malaysia to protect & cure sicknesses - and every part of the plant has its own usage.

For example, there are 5 parts, starting from the top of the Tongkat Ali plant. These are all above ground. The fruits are still currently used as a cure for diarrhea. The leafy greens are used for washing skin itchiness. The barks are used to combat intestinal worms in the stomach. Now the underground part. The taproot, which is closer to the upper soil is used to combat high blood pressure, diarrhea, as well as fever. And last & finally, the hidden treasure of the Tongkat Ali - the roots. Traditionally used as an aphrodisiac, also has the properties of the rest of the plant.

In the present age, backed by medical research and science, Tongkat Ali is now highly sought after for its rich benefits. Two of the 3 active ingredients found inside Tongkat Ali are Eurycomanone and Eurycomanol are effective in increasing free testosterone levels that help contribute to a better you.

It helps to build testosterone, vitality, muscle strength, & sexual desires. Reduces anxiety, stress, anger & improves mood. Reduces high blood pressure, diabetes.

It helps to avoid a condition call Andropause, which symptoms include lack of energy, increased body fat, mental lethargy, and low libido levels. Eurycomanone also stimulates the production of Adenosine Triphosphate (ATP) which gives the body energy and boosts performance levels particularly for athletes, bodybuilders, or anyone doing strenuous activities.


The third active ingredient, known as Eurycomanone is a substance that fights against cancer, high blood pressure, and diabetes.

Now that you have a brief understanding of what it does, let's dive deeper.

But before that, let me show you a quick before & after comparison chart of my own testosterone levels after taking Tongkat Ali for 1 month.

A short background of when I took it;

Before Covid-19 started, I stopped gym & once in a while I would workout once or twice a month for a year. My muscles were all gone, reverting back to a stick figure.

When Covid-19 was in its recovering stage in Malaysia, & gyms were allowed, I went to get a regular blood test & added testosterone levels to check. I always assumed I'm in great shape & lean so therefore my testosterone levels will always be high. I have never felt so wrong. I was in shock & complete disbelief that it could drop so low.

So, I combined Tongkat Ali & gym together for a good few months until cases started rising again. 

 But, in just 1 month of proper food, training, & Tongkat Ali - I'm back to my normal levels as a 30-year-old male. But of course, results can be different for you as my metabolic rate was already very high.

Tongkat Ali in the rainforests are commonly found everywhere, however, from what we've learned from the natives who have harvested them for decades, each type of Tongkat Ali can only grow in a certain part of the forest.

For example, Yellow can be found anywhere. Red is mostly up the slopes, Black is nearby swamps or lakes, & lastly, Ginseng Tongkat Ali is found commonly on the same grounds of Yellow Tongkat Ali.  Requirements to harvest any specific Tongkat Ali needs to be at least 5 years of age. (Pics above are at the minimal age for harvesting)

Yellow Tongkat Ali
Eurycoma Longifolia

Ranging from as young as a small shrub to the oldest reaching over more than 30 years old.

Yellow Tongkat Ali has been a prized natural herb for over 2 decades now & has been commercialized worldwide in stores. It is also the most known Tongkat Ali compared to Red, Black, & Ginseng.

Red Tongkat Ali
Stema Tuberosa / Jackia Ornata

Red Tongkat Ali or Malaysian Red Ginseng comes from a scientific plant known as Stema Tuberosa. This comes from a species known as Jackiopsis Ornate from the family of Rubaceae. This rare tree is found growing along rivers, sandy or swampy soil in virgin rainforests up to 400 metres altitude in Peninsular Malaysia.

The plant is similar to Stemona Tuberosa is also found in remote parts of China, Indonesia and Thailand. The root has it’s name due to its distinct strong red colour and after drying, usually it turns into light red. This root is also known by other name such as Akar Haji Samat by locals.

The only reason why it continued to be popular amongst locals is the acceptable taste.  The Red Tongkat Ali smells and taste like any ginseng. It can taste somewhat sweet, a total opposite compared to Yellow and Black Tongkat Ali. It also means that the level of eurycomanone is the lowest in the Red Tongkat Ali.

Has there been any research or scientific evidence done on Red Tongkat Ali to validate its health benefits? After hours of researching, we have found none! Most of the Tongkat Ali clinical trials and scientific studies were based on Eurycoma Longifolia (i.e Yellow Tongkat Ali).

The red ginseng is consumed as regular herbal tea or coffee to give a dose of energy by the Chinese. We cannot ascertain the level of lead or mercury in red ginseng, but it is believed to be safe as it is widely sold in raw slices (instead of capsules).

Aside from this, we did not find any approved brands sold in pharmacies that carries “Red Tongkat Ali” title. Due to lower acceptance and trust, perhaps you should consider twice from buying it from Amazon stores!

Black Tongkat Ali
Polyalthia Bullata

Black Tongkat Ali comes from a plant known as Polyalthia bullata with a small root at 2-3 cm in diameter, which is a significantly smaller diameter than yellow Tongkat Ali. Also known as Wild Black Gorilla, Tongkat Ali Baginda and Tongkat Ali Hitam, the Black Tongkat Ali is found along the rivers in the lowland forest of Peninsular Malaysia such in the state of Pahang.

How does it taste like? Black Tongkat Ali smells fishy (perhaps due to the location where it is generally found – i.e near the river), but generally tastes less bitter than Yellow Tongkat Ali.

Production of Black Tongkat Ali is rare although it is found to be exported in raw slices. While its healing efficacy is touted to be much better than Yellow Tongkat Ali, it is traditionally used by the indigenous as a natural aphrodisiac for men’s health. 

Beyond it’s only health claim, there was lack of research or published papers associated with Black Tongkat Ali found to date. This makes it less popular amongst those seeking for scientific validation and proof of its health benefits.

At the same time, we found no-approval by the Malaysian Health Drugs Authorities on Tongkat Ali products sold in pharmacies that carry the title “Black Tongkat Ali”.

research study showed that 26% out of 100 Black Tongkat Ali (or Tongkat Ali Hitam) products contain high mercury content between 0.53 – 2.35 ppm – higher than the allowable limit of 0.5 ppm.

Ginseng Tongkat Ali


Tongkat Ali Root also contains compounds Quassinoids & Alkaloids. The root is the only part that contains Eurycomanone & while other parts of the plant may also contain small traces of it. 


Soil & geography is crucial for Tongkat Ali's bioactive ingredient Eurycomanone to be present & strong. Which is what Tongkat Ali is prized for. There are several factors that affect the percentages in Eurycomanone levels in Tongkat Ali. For example, the geography of the island population, coastal population, & hill forest population.


The difference in Eurycomanone levels in Tongkat Ali found all over the states of Malaysia are also the result of different geographical locations, altitudes, temperatures, & moisture. However, there are still many other considerations to be taken & still more research to be done.

Now that you have a better understanding of Tongkat Ali,

let's go into questions people often ask

How does Tongkat Ali work in our body?

Tongkat Ali is a unique plant that works on a variety of levels involved with hormonal and sexual functions, because not only does it reduces the effects of temporal aging in the male's reproductive system, but by also enhancing the free bio-availability of testosterone from the body through the main parts of the body.

  • Boost luteinizing hormone (LH) secretion, which in turn stimulates the Leydig cells in your testicles to produce testosterone. 

  • Reduction of the conversion of testosterone into estrogen in men.

  • Reduction in SHBG, sex hormone-binding globulin.

  • Reduction in cortisol, the stress hormone that lowers testosterone.

The net result of these 4 effects is an increase in available free testosterone.

As testosterone ages become bound to serum globulin and is not available for cell receptor sites where it is necessary to initiate sex stimulation centers in the brain. The component in the bloodstream that makes testosterone inactive-free is called sex hormone-binding globulin (HFBG). Too much estrogen can boost SHBG production and block testosterone receptor sites. The average 54-year-old man often has higher estrogen rates than the average 59-year-old woman. While some estrogens are a hormone needed for men, too contribute to a broad spectrum of health, weight gain and libido problems. Because of the similarities in the chemical structure, elevated serum estrogen levels also deceive the brain by thinking that enough testosterone is produced, thus slowing down the natural production of testosterone. In order for testosterone to produce positive health effects, it must be preserved in its free form in the bloodstream. Bonded testosterone is unable to be captured by testosterone receptors on cellular membranes. For aging men, it is desirable to remove excess levels of SHBG and estrogen whilst stimulating free testosterone at the level of a young man. Tongkat Ali is a natural way to boost bio-available testosterone while also lowering levels of SHBG and estrogens in aging men. Results from studies to date have confirmed that Tongkat Ali could help in the following areas:

  • Elevating free testosterone level

  • Improving erectile strength without side effects

  • Increase in male fertility, sperm quality, motility and quantity

  • Natural energizer

  • Safely and meaningfully boosts androgen levels

  • Improving strength during exercise with an anabolic effect on muscle growth

  • Decrease in sex hormone binding globulin (SHBG)

  • May promote weight loss

  • May reduce conversion of testosterone to estrogen (anti-aromatase effect)

In summary, these combined effects position Tongkat Ali as perhaps the safest and most effective herbal testosterone enhancing medicinal plant available today. It is particularly suitable for slowing down or reversing the so called male andropause that occurs in middle-age and is of benefit for athletes and bodybuilders looking for a natural supplement without side-effects.

Below are charts depicting each mood of before and after taking Tongkat Ali

1st to left, before Tongkat Ali was taken.

2nd to left, before a placebo different than Tongkat Ali was taken.

3rd to left, after Tongkat Ali was taken.

4th to left, after a placebo was taken.

Mood results of before and after Tongkat Ali as well as a placebo.

Daily supplementation (200 mg/day for 4 weeks) with Tongkat Ali (TA) resulted in significant improvements compared to placebo (PL) for indices of:


Tension (−11%),

Anger (−12%), and

Confusion (−15%) in moderately stressed adults

Salivary cortisol levels were significantly lower (−16% compared to placebo, PL) following Tongkat Ali (TA) supplementation (200 mg/day for 4 weeks)

Salivary testosterone levels were significantly higher (+37% compared to placebo, PL) following Tongkat Ali (TA) supplementation (200 mg/day for 4 weeks).



Significant improvements were found in the Tongkat Ali group for:-

Tension (−11%),

Anger (−12%), and

Confusion (−15%).

Stress hormone profile (salivary cortisol and testosterone) was significantly improved by Tongkat Ali supplementation, with

Reduced Cortisol exposure (−16%) and

Increased Testosterone status (+37%).



These results indicate that daily supplementation with Tongkat Ali root extract improves stress hormone profile and certain mood state parameters, suggesting that this “ancient” remedy may be an effective approach to shielding the body from the detrimental effects of “modern” chronic stress, which may include general day-to-day stress, as well as the stress of dieting, sleep deprivation, and exercise training.

Can I still take Tongkat Ali even though I have high blood presure?

Yes, absolutely! Tongkat Ali has a mild anti-hypertensive vasodilator effect, which basically means it will not aggravate your blood pressure at all and is one of the reasons that Tongkat Ali can be used as an alternative other than the medicinal method. This is also another reason Tongkat Ali works for males with erectile dysfunction because of its circulation effect.

What's your opinion about 100:1 and 200:1 ratios of Tongkat Ali extracts?

Tongkat Ali extract must be tested for it's Eurycomanone content and not for the outdated "ratio method" that is completely unverifiable and unprofessional. Ask any phytochemist who has extracted Tongkat Ali and they will tell you that a 30:1 concentration extract is the maximum ratio of herb to extract that is obtainable from Tongkat Ali after which you would need to be selectively separating its individual components. It's unfortunate but those claiming to have Tongkat Ali extraction ratios of 100:1, and even the absurd 200:1 are false and only made by marketing people, not scientists. One company started this off several years ago and everyone else (except for Rainforest Herbs) has felt it was necessary to perpetuate the claim in order to be competitive.

Conspicuously absent from all these companies is any mention of studies on the active ingredient marker in Tongkat Ali, Eurycomanone. Eurycomanone is the prominent bioactive quassinoid present in Tongkat Ali that is used as a marker and should be present @ >2% Eurycomanone for a daily dosage of 600mg to 900mg. The Eurycomanone concentration of the extract and daily dosage needs to be adjusted accordingly for an effective product. For example, a product that contains only 75mg of a 3% Eurycomanone extract (claiming to be 100:1) will be below the therapeutic dosage and thus the concentration of the original extract is meaningless when the dosage used in the capsule is too low.

Another issue is that the colour of an extract does not offer any clue to its quality or concentration, as a darker coloured extract may indeed be only "burnt" during excessive heating, especially by poor quality drying processes with subsequent loss of properties due to unregulated heat. Assay for glycosaponins is a standard in phytochemistry especially for products that elicit an effect on the male reproductive system. For example the majority of known active ingredients in Korean Ginseng are also glycosaponins. Finally, when you purchase a product from a Company claiming a 200:1 extract then you are likely buying a reverse engineered China extract that may not contain any Tongkat Ali extract at all, but in fact a different herb that contains similar organoleptic (taste, smell etc.) characteristics.

Numerous commercial tongkat ali supplements claim “extract ratios” from 1:20 to 1:200 without any information about bioactive constituents, extraction methodology (e.g. ethanol versus water), or extract purity. Alcohol extracts of eurycoma have been studied in mice for antimalarial effects of concentrated eurycomalactone [23] but also exhibit toxic effects at high doses (LD50 at 2.6 g/kg), which would preclude safe use in humans as a long-term dietary supplement [24,25]. In contrast, hot-water root extracts standardized for known bioactive components (1% eurycomanone, 22% protein, 30% polysaccharides, 35% glycosaponin) have been demonstrated to be extremely safe at high doses and for long-term consumption [26-28].

Properly standardized hot-water extracts [2,26,29] have a distinctly bitter taste due to the presence of quassinoids, which are recognized as some of the bitterest compounds in nature [30,31]. Tongkat ali extracts that do not taste bitter are either not true Eurycoma longifolia root (there are many commercial examples of “fake” tongkat ali extracts) or are sub-potent in terms of bioactive constituents, and thus would also be expected to have low efficacy. Because of tongkat ali’s reputation for libido benefits, there are several examples of dietary supplements labeled as Eurycoma longifolia, but containing none of the actual root, and instead being “spiked” with prescription erectile dysfunction drugs including tadalafil/Cialis, sildenafil/Viagra, and vardenafil/Levitra [4, personal communication].
