What is Tongkat Ali?
Tongkat Ali, botanical name Eurycoma Longifolia Jack, also known as Long Jack, Pasak Bumi, Tungsaw and Malaysian Ginseng, is a rare plant found in Southeast Asia.
Tongkat Ali can be found in Indonesia (Sumatra and Borneo) and Indochina (Malaysia, Vietnam, Laos, Myanmar and Thailand) and the Philippines.
What is Tongkat used for?
Sadly it is forbidden for european based sellers of herbal products to make health claims about them, therefore we cannot answer this question fully since any other benefits or use cases described may be mistaken as medicinal claims by some, even if they are not. You must do your own research.
Tongkat Studies and Research
What are the active constituents of Tongkat Ali
Below is an image taken from a scientific site showing the many known active constituents.
What does Tongkat Ali mean?
The word "Tongkat Ali" is Malaysian and translates to "Ali's¬†walking stick", because of the long thin trunk of the tree which resembles a huge walking stick. Some also say it is an innuendo.
Is Tongkat a protected species?
Some people claim Tongkat is a protected species, however according to FRIM (Forest Research Institute of Malaysia), the plant can still be harvested in the wild legally, but there are now protected national parks and reserves containing Tongkat Ali in Malaysia to prevent extinction and harvesting from these areas only is forbidden. Raw roots can no longer be exported from Malaysia either, but the finished extract can. Some Malaysian manufacturers also import the roots from Indonesia. The above can be verified by contacting FRIM yourself, their site is https://www.frim.gov.my
Tongkat Ali and Heavy Metals
Many years ago in 1992, 100 Tongkat products from Malaysia were tested and 26% of these were found to contain high levels of mercury, because the roots were taken from forests close to built-up areas with high traffic and pollutants. This was years ago, did not affect the majority of manufacturers, and is no longer an issue as far as I am aware, but still, some sellers from Indonesia will say to avoid Malaysian extract because of this in an attempt to put people off rival products.
The report can be found at https://pubmed.ncbi.nlm.nih.gov/16567029/
PowerOfTheHerb.com sells an extract that uses Indonesian grown roots, but unlike other sellers we will not lie to you and say it is better than Malaysian extracts or polluted, because the 2 countries produce extracts of equal quality, and of equally bad quality, depending on who you buy it from. Both countries have honest sellers and dishonest sellers.
Are there any plantations?
There are some field plantations, the oldest of which I know of mentioned is 7 years old, see HERE for proof of this in a study.
There are even modern and safe ways of growing Tongkat Ali to increase the active ingredients in the plant's roots, and even increase the number of shoots from 1, which is all a wild grown plant will have, to 6!
A study that you can download HERE has proven not only the above, but also that it is now possible to yield more Eurycomanone from a 1-year old cultivated plant than a mature wild plant, meaning in the future harvesting mature plants in to near extinction will no longer be needed, which is of course great news for the declining species and for manufacturers. It may even bring the price down if it ever happens on a large scale.
Do not believe dishonest manufacturers or people who say the root must be at least 10 years of age to be beneficial, it probably is not 10 years old at all even if it is advertised as such, and in this day and age with today's technology and extraction methods the age is not really important at all, unless of course you are using very old and more traditional/simple methods of extraction, in which case it may make a difference.
How many species of Tongkat / Longjack exist?
There are a total four species being referred by locals as Tongkat Ali according to the Journal of applied science. The species are...
Eurycoma longifolia Jack, also known as Long Jack, which is yellow/beige in color in its raw form and is the most studied and the most used for extracts. When people talk about Tongkat Ali, this is usually what they are referring to and is really the only species you should consider if you are basing your purchase on studies.
Polyathia bullata, also known as Hitam, which is Black/dark brown on the outside and creamy white on the inside, sometimes called King. Also used in extracts by some manufacturers though not as much as it is not very well studied.
Eurycoma apiculata, very little info about this species online.
Goniothalamus sp, very little info about this species available online.
Another plant called Jackiopsis ornata, also known as Merah, which has reddish pink tinge to it is often called Red Tongkat Ali by some people in Malaysia, although it is not actually a member of the same species and is unlikely to have the same benefits. It is said to have a pleasant Ginseng like taste.
What is a standardized / standardised Tongkat Ali extract?
A standardized extract, spelt with either an S or a Z depending on where you are from, is an extract that was created with set standards, usually to contain a specific percentage of an active constituent or constituents that have shown to be effective for whatever the herb is being sold for. In the case of Tongkat Ali, eurycomanone is the most common constituent for standardization as it is the most studied and looks to be one of the most beneficial.
Some manufacturers may also produce an extract using normal methods, and test every batch for the eurycomanone content after the extract has been created. If it meets or exceeds the percentage they require, it can be kept, If not then it cannot be used for that specific product and may be discarded, used in another product or modified until it does meet the requirements.
In Malaysia, it is said that all Tongkat Ali extract products should contain at least 0.8% Eurycomanone to be deemed effective, although this is a worst case scenario and ideally you want at least 2%. There are still plenty of fakes in circulation that contain none at all as it is not properly policed at this time.
World A.B.S' extract is Standardized using HPLC analyzation during the extraction phase and any extract that does not meet the 2.4% eurycomanone standard is adjusted accordingly.
A great article on the importance of standardization can be found¬†here.
The problem with none-standardized extracts (extract ratios).
The problem with herbs sold with only extract ratios, such as 1.20, 1.50 , 1:100, 1.200 etc, is that it is impossible to know if the herb or even the extract ratio given is real, since no tests exist to test for extract ratios. There are simply too many factors and variations involved in the production process that may affect the amount of raw herb needed to be used.
Unless you are literally stood inside the room watching it being manufactured, you cannot know how much raw root was used and therefore have no way at all of knowing the real extract ratio. Hence many sellers will state 1:200 even if it's only 1.30 for example, because people think 1:200 means it is strong and potent, but this is not always the case.
HOWEVER if you standardize an extract to make sure it contains 2-3% Eurycomanone, which is exactly what World A.B.S have done and others are starting to do, then you can be sure it is going to be genuine and should also contain a good amount of other active constituents regardless of the extract ratio. When standardized each batch will also be consistent in potency and quality.
The only real downside to standardization is that to increase the percentage of one constituent others may need to be reduced, this may or may not decrease the desired effect depending on what you are trying to achieve. Since eurycomanone is one of the major and most studied of Tongkat Ali's constituents and the product sold here is standardised to 2.4% eurycomanone, this is not an issue as it it can still offer the full spectrum of active constituents.
Some companies claim 8% or higher, but then because of the costs needed to produce an 8% extract they will only put 100mg of that extract in the capsules, so you actually get LESS eurycomanone than you would in a lower percentage product that has 300-400mg in the capsules AND you get LESS of the other active constituents also, for example...
100mg at 8% is 8mg of eurycomanone and 92mg of the other constituents per capsule and a high price tag.
400mg at 2.4% is 9.6mg of Eurycomanone and 390.4mg of the other active constituents, with a lower price tag. This makes the 100mg 8% product more expensive and also inferior.
Higher than 8% is incredibly rare for a herbal retailer and if ridiculous claims are made, such as 10 - 25% at a low price, they are probably not true.
For more info about plant extracts and how they are made etc, there is plenty of information at www.ahpa.org about all sorts of things herbal, and an article explaining about extracts in more details can be found HERE.

What is the Color of Tongkat Ali Extract?
You will have no doubt heard some people say it should be dark brown and others light brown or tan/beige/yellow etc. The truth is that there is no color or shade that it "should" be and never has been or will be, the color may be determined by a number of factors such as temperatures used, exposure time to these temperatures, extraction methods, extract solvents used, extraction times, species used, drying methods etc. This applies to most herbs.
Tongkat Ali / Long Jack could be whitish-yellow, yellow, creamy white, pink, pinky brown, reddish brown, tan brown, dark brown etc, it honestly makes no difference whatsoever to the quality of the product.
Of course you will find sellers of dark extracts saying it should be dark and sellers of light extracts saying it should be light, blah blah blah, etc etc. You can ignore every single one of them as none of them have any proof for what they say and it is simply a dishonest marketing technique, or sometimes lack of knowledge from resellers who just repeat what their supplier tells them in the hope it will put people off buying products of a different color.
Traditional extraction methods using high temps for long periods and milling tend to be darker, newer methods of extraction such as high-pressure extraction, and drying methods like freeze and spray drying, tend to produce lighter extracts as although the temperatures can be high they are only exposed to them for a fraction of the time, a few seconds instead of hours.
In fact, you can take a light extract, put it in an oven on a high temp and darken it up yourself to see what effect high temp extraction and drying methods would have. It will turn dark brown, proving temps affect the color. In fact, most things turn dark brown when exposed to high temps, right before they turn black and burn!
Below is what World A.B.S, who produce the products we sell, say about their extract...
Due to the process used to produce the new 2.4% eurycomanone HPLC Standardized Tongkat Ali extract, the color may vary from batch to batch. The color will range from a sandy brown to a slightly darker reddish brown. This variation arises from the color of the Tongkat Ali root used, the color of the chosen extract that passes the required specifications and also the drying process used.
¬†HPLC Standardized Extraction
One of the many benefits of using the HPLC standardized extract is that Tongkat Ali root can be sourced based on its sustainability, rather than color or age. World A.B.S allow the HPLC testing to monitor the strength of the extract during the liquid stage before going on to the drying phase.
This technique drys the extract without overheating it, unlike the¬†traditional drying process that often darkens the color.
In traditional Tongkat Ali extraction, a vacuum drying process is commonly used. This longer exposure to higher temperatures will often overheat the extract damaging the active ingredients darkening the extract further, and in some instances reduce the extract almost to a charcoal state.
Other things of note regarding color...
I have had a few people recently emailing in asking about the color of Tongkat Ali extract, because they have read a few false statements on another brands site, which sells what is claimed to be 1:200 Tongkat in bigger capsules, that Tongkat Ali is "more impure the darker the color" This is obviously marketing hype which holds no truth whatsoever, and is very confusing for customers.
The statement they use is...
“Eurycomanone is snow white. The further from white an extract is the more impurities it contains.”
Yes, Eurycomanone "as a single constituent in its pure form when not attached to anything else" is White, BUT this is irrelevant and has nothing at all to do with regular herbal extracts in any way, shape or form, and is nothing at all to do with how pure or impure Tongkat Ali extract is. I will explain why in simple terms below...
Oranges are Orange, everyone knows this!
Pure Orange juice is Orange, everyone knows this!
Vitamin C, which is one of the many constituents in Oranges and the most well known, just like Eurycomanone is one of the many constituents in Tongkat Ali and the most well known, is white when removed and viewed in its pure form.
Everyone that has purchased Vitamin C powder knows this. Vitamin C powder is usually crystalline and white for those that don't know!
This obviously does not mean the further from White your Orange juice is, the less pure it is! Yet that is what the seller of the light extract does indeed state and seems to want you to believe, based on just one constituent being white, which is actually quite common. Removing solitary constituents from any herb or plant, regardless of what it is, almost always results in a color different to the plant or herb it came from, and that color is very often WHITE!

How is Tongkat Ali Extract Produced?
All production methods tend to be very similar, but times, extract solutions, extraction temperatures, species, parts of the plant used and the final drying method into an extract powder may vary.
Basically, the roots are heated in a liquid solvent, which can be water, ethanol, methanol or grain alcohol, for a period of time, and then removed from the solvent. The remaining liquid is then evaporated until all that remains is the extract from within the plant. This is then milled, spray dried or freeze dried into a fine powder.
Standardized extracts are monitored during the liquid phase using high-pressure liquid chromatography for levels of known active marker compounds such as eurycomanone to ensure the finished product is both real and potent and of a standard that can be repeated batch to batch. Another method would be to test the extract after extraction and either dispose of it if it does not meet requirements or alter it until it does, but this would take longer and likely be more expensive.
