Dosage for a woman
Since women are smaller and weigh less than men, the dose for a female should be roughly two thirds than the dose in a male. Tongkat does work to boost libido in a woman.

Tongkat Ali mechanism of action, does it boost testosterone?
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. I have read promotional material by some vitamin companies regarding tongkat ali that it enhances testosterone production or release, however we have not been able to definitively confirm this claim through a Medline search.

What the Research Says about Tongkat Ali as a libido enhancer, does it work?

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. Tongkat ali also increased the frequency of the rats’ erections.

Q.  I noticed on my last shipment that the Tonkgat Ali went from 400mg to 200mg per capsule. I was wondering whether I should take 1 or two capsules.
A. The tongkat ali was reduced to 200 mg but it went from 30 caps to 60 caps for the same price. Some people were having side effects taking 400 mg and Dr. Sahelian now feels it is better to enhance sexuality slowly on a lower dosage rather than quickly with side effects.

Medical conditions that have been studied
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.

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 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.

Q. I was reading on your website and it said taking high doses tongkat ali root extract for impotence has side effects. I am currently using tongkat ali toot extract and I take 50 mg daily as directed is this too much? I am using it for about 3 days now but I don’t notice anything different or side effects.
A. It’s difficult for us to say without knowing the potency, concentration or the quality of the herbal product. Sometimes tongkat ali side effects begin after several days of high dosage use.

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.
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.

Contamination and evaluation in Malaysia
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.
The DCA (Drug Control Authority), Malaysia, has implemented registration of traditional medicines 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 the plant were analyzed for mercury content. 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. 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, products cannot be assumed safe from mercury contamination because of batch-to-batch inconsistency.
