What the Research Says about Tongkat Ali:
Aphrodisiac
Over the past few years, there have been quite a number of studies that have shown tongkat ali  to have libido-boosting properties. The effects of tongkat ali were studied on the libido of male rats after dosing them with up to 800 mg per kilogram of body weight twice daily for 10 days (this is quite a high dose if the same dose is given to humans-- do the math: 800 mg tongkat ali powder times 70 k). Results showed that tongkat ali produced a dose-dependent increase in mounting frequency, that is, the number of times the male rats tried to mount the female rats increased as the dose given to the rats increased. In addition, the rats given tongkat ali displayed more frequent and vigorous licking and anogenital sniffing towards the receptive females. Furthermore, the rats dosed with tongkat ali  spent more time grooming their genitals compared to the rats who were not given the plant. Genital grooming may be interpreted as self-pleasuring since the rats were most likely enjoying the sensation of touching themselves. The researchers noticed another interesting finding: while the rats who had not received tongkat ali showed normal behavior within the cage such as exploration and climbing the cage wall, the rats given tongkat ali stayed around the females instead of exploring the cage. In human terms this may be interpreted as a man spending more time in the kitchen helping his wife wash the dishes than in the den lounged in a Lazyboy chair absorbed by a baseball game :). Tongkat ali also increased the frequency of the rats' erections. For more information on impotence herbs.
   Tongkat ali is a potent aphrodisiac, sometimes too potent. In order to get a quick sexual enhancement, a high dose is needed. But this high dose, even if taken in the morning, can cause insomnia that evening. A high dose can also cause restlessness and increased body temperature. We prefer to enhance sexuality the slow way, by taking a lower amount and being patient for a period of several days. Tongkat ali is found in Passion Rx with an amount of tongkat ali that minimizes the side effects of overstimulation and insomnia.

Passion Rx with tongkat ali herb
 Some of the herbs in Passion Rx include Ashwagandha, Catuaba, Cnidium, Muira Puama herb, Tribulus, Tongkat ali, and Yohimbe. Passion Rx does not have Arginine. A concentrated form of tongkat ali is LJ100. The use of Passion Rx leads to better orgasms.

Tongkat Ali and Cancer
Beta-carboline alkaloids isolated from tongkat ali have demonstrated significant cytotoxicity against human lung cancer (A-549) and human breast cancer (MCF-7) cell lines. In plain English, this means that some compounds in Tongkat ali can kill cancer cells. The practical significance of this finding in humans is not clear at this time.
   Numerous rodent studies show tongkat ali to have aphrodisiac properties. But, this herb has additional properties, including anti-malarial and anti-breast tumor activity. A report published by researchers at the National University in Malaysia indicates certain extracts in tongkat ali can slow the growth of breast cancer cell line MCF-7. It is too soon to tell whether a small amount of tongkat ali taken most days of the week, would be appropriate for those with breast cancer. What happens in a laboratory dish does not necessarily reflect what happens in the whole body when an herb is ingested on a daily basis.

Tongkat Ali and Malaria
Interestingly, scientists have found that, in addition to its sex-enhancing effects, compounds within tongkat ali  have anti-malarial properties.

Tongkat Ali Mechanism of action
Very little is known regarding the mechanisms of action of tongkat ali. Recent studies indicate that the root contains several compounds including beta-carboline alkaloids and quassinoid-type glycosides, including eurycomaoside. How these compounds and many others in tongkat ali influence hormoneal reliase or the human sexual response is not clearly understood at this time. We have read promotional material by some vitamin companies regarding tongkat ali that it enhances testosterone production or release, however weI have not been able to definitively confirm this claim through a Medline search.

Availability of Tongkat Ali
Tongkat Ali is sold as a powder, and in capsules, sometimes mixed with other herbs. There are a number of extracts available in various potencies, and since each company has a different way of extracting, and since there are no established standards, it is difficult to give dosage recommendations that would be consistently effective. In addition to tongkat ali being available as a raw powder, it is sold as a 4:1, 5:1, 20:1 and a 100:1 concentration. At the higher concentrations it becomes difficult to dose appropriately since the margin of error in terms of effectiveness versus side effects becomes more challenging. Tongkat ali is alos known as longjack.

Tongkat Ali Side Effects
One of the shortcomings of Tongkat Ali  is that it can easily cause insomnia, and lack of sleep can lower sex drive. Therefore it is somewhat difficult to find the right dose that works without causing this insomnia, and that's where an experienced herbalist who has wide knowledge with this plant is crucial in terms of formulating the right product with the right amount and extract potency of tongkat ali. High doses can also cause increased body temperature. Some people find that when they take a high dose, they become restless and impatient, perhaps easily angered. Long term effects of tongkat ali on human consumption are not known. It is best, until we learn more, to not take tongkat ali continuously without breaks.

Road rage is defiantly a side effect, I use a strong extra strength for 10 weeks straight with a 3 week break to get my testosterone levels up high, you feel a million bucks and get some serious muscle gains when working out but you do get angry at lame drivers, you are so impatient when people drive slow on the road or freeway.

Tongkat Ali Research Update
Eurycoma longifolia Jack enhances sexual motivation in middle-aged male mice.
Ang HH. University Science Malaysia, Minden, Penang, Malaysia. J Basic Clin Physiol Pharmacol. 2003;14(3):301-8.
 Tongkat Ali  was investigated for sexual motivation activity in adult, middle-aged male mice and in retired breeders, using the modified open field and the modified runway choice methods. Each mouse received 500 mg/kg of one of 4 fractions of E. longifolia Jack, viz. chloroform, methanol, butanol, and water, whereas the mice in the control and yohimbine groups received 3 ml/kg of normal saline and 30 mg/kg of yohimbine daily respectively for 10 d. The results show a transient increase in the percentage of male mice responding to the right choice after chronic consumption of the fractions with 50 percent of the adult middle-aged male mice treated with E. longifolia Jack and yohimbine scoring the right choice after 8 and 5 days post-treatment respectively. In conclusion, this study has shown that Tongkat Ali continues to enhance sexual motivation in adult, middle-aged male mice and in retired breeders.

Determination of mercury by cold vapor atomic absorption spectrophotometer in Tongkat Ali preparations obtained in Malaysia.
Ang HH, Lee EL.  University Science Malaysia, Minden, Penang, Malaysia. Int J Toxicol. 2004 Jan-Feb;23(1):65-71.
The DCA (Drug Control Authority), Malaysia, has implemented the phase 3 registration of traditional medicines on 1 January 1992, with special emphasis on the quality, efficacy, and safety (including the presence of heavy metals) in all pharmaceutical dosage forms of traditional medicine preparations such as tongkat ali. As such, a total of 100 products in various pharmaceutical dosage forms of a herbal preparation, containing Tongkat Ali, were analyzed for mercury content using cold vapor atomic absorption spectrophotometer. Results showed that 36% of the tongkat ali products possessed 0.52 to 5.30 ppm of mercury and, therefore, do not comply with the quality requirement for traditional medicines in Malaysia. Out of these 36 tongkat ali products, 5 products that possessed 1.05 to 4.41 ppm of mercury were in fact have already registered with the DCA, Malaysia. However, the rest of the tongkat ali products that contain 0.52 to 5.30 ppm of mercury still have not registered with the DCA, Malaysia. Although this study showed that only 64% of the tongkat ali products complied with the quality requirement for traditional medicines in Malaysia pertaining to mercury, tongkat ali products cannot be assumed safe from mercury contamination because of batch-to-batch inconsistency.

Tongkat Ali emails
Q. I get severe insomnia when I take Tongkat ali. Is this common?
A. Insomnia is one of the major side effects of Tongkat ali and is one of the limiting factors in its use in high doses.

Q. Can tongkat ali be combined with other herbs such as yohimbe or hormy goat weed?
A. I can only speak from my personal and professional experience. Thus far I have combined tongkat ali with several herbs and have found that when high doses of  tongkat ali are taken with other herbs that have stimulating properties, such as ginseng or other adaptogens, there is the potential for restlessness, irritability, and insomnia.

Q. Does tongkat ali give more energy?
A. I believe tongkat ali is a strong energy booster. I find that after 2 or 3 days of taking tongka ali, there is a general sense of enhanced energy that occurs. However, if I take a high dose of tongkat ali, the resulting shallow sleep from the overstimulation can lower my energy levels. I also find that high doses of tongkat ali make me feel restless. For instance, I find that I am less patient and more irritable, particularly if I have taken tongkat ali and I am stuck in traffic on one of the freeways in Los Angeles.

Q. Can I take tongkat ali regularly for many months?
A. As with most herbs, I recommend taking breaks from use. In the case of tongkat ali, you could take it for 2 or 3 days and take a few days off.

Q. How many different types of Tongkat ali extract are available?
A. The ones I have seen are the following: Tongkat ali powder, Tongkat ali 20:1, Tongkat ali 50:1, and Tongkat ali 100:1 extracts.

Q. Can tongkat ali be taken with fish oils?
A. Yes, I don't see any problems combining fish oils with tongkat ali.

Q. I have chronic fatigue symdrome. Is tongkat ali helpful?
A. It depends what's causing the chronic fatigue. Tongkat ali does increase energy levels, but it can also cause insomnia in high doses so you have to balance the energy and the insomnia. Find a low dose of tongkat ali to increase energy yet not cause disrupted sleep.

Q. My concerns are that there are a lot of different folks that say their tongkat ali product is effective. What is the "actual" percentage of the main ingredient in the Physician Formulas tongkat ali formula. Many folks claim that there is hardly any of the real tongkat ali in the off the shelf stuff we buy here in the U.S. I am a Physician Formulas customer.
   A. Dr. Ray Sahelian personally reviews each product formulated by Physician Formulas. There is misinformation on the internet about the quality of tongkat ali sold in the US and much of this information is promulgated by websites based in Asia. Tongkat ali is potent and we suggest using half of the 400 mg tongkat ali powder or just once capsule of LJ100 25 mg. Another option is Passion Rx with yohimbe which has LJ100 in it and is a popular product.

Q. I am a 53 year old male who has had testosterone deficiency on occasion from the results of blood tests for physicals I've had the past few years. I did supplement with 25 mg of DHEA for about a year, and that seemed to help with the levels. However, I've backed off the DHEA because of the known risks. I've recently been experimenting with Tongkat Ali, LJ100, and Longjax. I plan to cycle the products 3 days on 2 off, or some similar pattern. Do you think my cycling of these products is appropriate? Do you think that the Longjax 20:1 done over time and cycled will
consistently keep my testosterone levels healthy? Are there any dangers I should be aware of that aren't posted on your website? Will I feel "low" on days when I don't take the Longjax, LJ100 or Tongat Ali? In other words, on those days when I cycle off, will I feel a loss of energy, or will the accumulated effect of the herb carry me through?
   A. Not enough long term research has been done with tongkat ali or the extract LJ100 or Longjax to know the full range of risks and dangers. These herbs are not meant to be used all the time, but only to enhance sexuality and used as little as possible.

Q. I was thinking of taking tongkat ali because of decreased libido from taking Propecia for a long time. Since you do research on herbs, i was curious to know if there are herbs or anything natural other than Propecia and Minoxidil to stop hair loss and regrow hair.
   A. Please see hair web page.

Q. I have been reading a lot on tongkat ali. It seems that it increases free testosterone. Some say by 400%. Is this true? Do you know to what degree there will be in an increase in free testosterone in a person's body. Does increased free testosterone makes one lose hair. I am on Propecia now and have low libido from taking Propecia.
   A. There is very little research in humans regarding the influence of tongkat ali on testosterone levels in the long term. We have not come across any studies regarding the influence of tongkat ali on hair growth. Tongkat ali or Passion Rx can reverse the low libido due to Propecia use.

Q. Is passion Rx safe to take while trying to have a baby?
   A. We have no experience of reports of pregnant women using Passion Rx during pregnancy or while trying to become pregnant so we can't claim it is safe. As a general rule, it is a good idea to take as few herbs while trying to become pregnant or during pregnancy unless that herbs have been studied in humans and found to be safe during pregnancy.

Q. Before ordering tongkat Ali I would like to know which one is more potent and what are the gel caps made of? Can the caps be opened and the powder consumed in water or some other liquid? I believe tongkat ali can help me and restore some of the sensitivity I lost. Mainly the glans area of the penis.
   A. Both tongkat ali powder and LJ100 are potent. The capsules are made of gelatin. The capsules can be opened and the contents emptied into juice or water but the taste is bitter. Use low dosages since this herb is quite potent, it can enhance sensitivity but do read the side effects.

Q. I have been doing a lot of reading and research on Tongkat Ali, in terms of increasing libido. I am understanding that it has to do with testosterone levels. But, how does this specifically affect women (I am a female)? I have read that women can take it and experience benefits, but is there any more information you can tell me? Does tongkat ali make a woman grow facial hair, or any of those scary side effects of steroids ( I understand this is not a steroid, I'm just making a comparison with the testosterone) we hear about? Also, what is the difference between Tongkat Ali and Kacip Fatimah? I have read that the kacip fatimah is the female version of tongkat ali, but what is the difference? Does one work more effectively on women than the other? Does tongkat ali have negative side physical side effects on women? I understand it has to do with dosage, etc, but can you tell me the difference in general between the two? Right now, I am leaning toward Tongkat Ali to increase my low libido and help my sexual appetite, and it also seems that is the main function of the herb, whereas kacip fatimah has a lot to do with menstrual and post-partum problems.
   A. Tongkat ali and kacip fatimah (Labisia pumila) are different plants with different chemical compositions. Very little human research has been done with kacip fatimah. Women also notice sexual enhancement benefits from the use of tongkat ali. Tongkat ali does not make a woman grow facial hair. The exact mechanisms by which tongkat ali works to enhance sexuality are not fully known, but it likely has to do with much more than influencing testosterone levels. This herb is potent and is not taken on a daily basis.

Q. I am a 25 y/o male who has never taken steroids or prohormones in his life. I recently decided to experiment with Tongkat Ali extract to give me an extra boost at the gym and elevate my testosterone levels. I took it a long with Di-Indolyl-Methane (DIM) I've read in different studies that it was OK to take on a daily basis, but after coming to your website I noticed you say only take a few days out of the week. To make a long story short using this tongkat ali product actually lowered my libido and my testosterone level. I have since then stopped taking the product and am waiting for my testosterone levels to go back to normal. I was only supplementing for 3 weeks. I've read that levels should go back to normal after the dosing stops? Do you have any research or feedback on this?
   A. After a week or two hormone levels should return to normal. Many sexual herbs work better when not used every day. In addition to altering hormone levels, these herbs, including tongkat ali, could disturb sleep patterns which can reduce sexual drive. In the meantime it is best not to take any supplements, reduce caffeine and alcohol intake, and take walks during the day and get a deep sleep at night. Deep sleep is restorative to hormone levels.

Q. i have been using the Passion rx without yohimbe, and i just purchased some tongkat ali. i know u recommend two days off and two days off for Passion rx and tongkat ali / lj 100. U also recommend not taking them at the same time. anyways i took passion rx too many consecutive days in a row along with lj 100. My libido went from being great to being shot. I was researching about tongkat ali and Dr. Ray Sahelian wrote, "There is a tolerance that builds up to some herbs, and tongkat ali is one of them. Perhaps tongkat stimulates hormone release which depletes after a while and you may need to take a break from use to replenish the hormones, or maybe there are other factors involved that we don't know about." Let's say that it does stimulate hormone release which depletes after awhile. I am taking a break, but i was wondering if there was anything else i could do to replenish my hormones. Would weight lifting and exercising help, or deplete it more? would certain foods like soy or eggs or anything help?
   A. it is best not to not take any supplements that have a stimulating nature or that disturb sleep or increase body temperature. Take walks during the day and get a deep sleep at night. Deep sleep is restorative to hormone levels. Eating more fish or taking fish oil capsules may be helpful. Weight lifting is okay in moderation but not excessively.

Q.  I own a factory for coffee mix and want to produce a new product with Tongkat ( Male ) or Kacip Fatima ( Female ). I'll put also Horny Goat Weed , While Main Ingredients is ( Instant Coffee 49%, Non-Dairy Creamer 32% ) and the rest 20% is for the Herbs; The Question now : Is this good percentages for more than aphrodisiac drink? Is there any conflict or harm when Tongkat is mixed with components above and i mean specially caffeine in the coffee? Which type of Tongkat Ali should i mix with the drink ( In Powder State ) and i mean powder, powdered capsules, roots powder, or Extract Powder, and 1:50 or 1:100, 1:150, 1:200, please explain? Is it necessary to add Tribulus Terrestis, or Tongkat is powerful enough?
   A. These are types of questions that are of commercial nature and you may wish to contact Dr. Ray Sahelian, M.D., an expert, for a consultation.

 just purchased one bottle of tongkat ali 25mg extract. I did futher research and came upon two things that upset me a bit. I read in numerous places that 25 mgs is not nearly a high enough does to get any results and that one should always buy Indonesian Tongkat and not Malaysian.
    There is a lot of misinformation on the internet regarding this herb. We suggest you focus instead on this tongkat ali site for accurate information.

I saw the your web site and pretty impressed but when i saw another website i become little confused. The other company is selling sd200, both products are more expensive than LJ100 as they claimed that thy are producing a pure product in the markeet. They also recommended a dosage sd200 of 600 mg a day. Their recommended dosage is way more then your recommended dosage (25mg).Please guide me and tell me whats a difference b/w your product and sd200. Does your products made by indonasia or malaysia.
    There is a lot of misinformation on the market, we suggest not relying on information by websites that do not list a real physical address or are located overseas, you just can't trust them. SD200 product must be very weak if 600 mg is needed to have an effect.

I just recently purchased a bottle of tongkat ali on club natural. I heard the Malyasian tongkat ali has a high content of lead. it sais that club naturals is from Malaysia rather than Indonesia. Is there any truth to this?
    There is no evidence that lead is present in higher amounts in tongkat ali from Malaysia versus Indonesia. Before the tongkat ali products are released to the public, lead levels are measured by the manufacturers.

By far this is one of the most sex enhancing producing herbs...lately myself and my friends have been taking it in a coffee.
