EURYCOMA LONGIFOLIA = TONGKAT ALI
Eurycoma Longifolia Jack is the herb name for what is more commonly known as Tongkat Ali, Malaysian Ginseng, or Longjack.
Eurycoma (Tongkat Ali, LongJack) is a pro-fertility agent and aphrodisiac that appears to have a large body of evidence supporting this role and some evidence suggesting it may be an anti-estrogen and pro-erectile agent. terone boosting.
The root of Eurycoma Longifolia itself contains several chemicals that have different effects in the body. Some of the chemicals seem to affect how the body produces the hormone testosterone. Research in animals and humans suggests it might increase testosterone in the body.
In addition to the aphrodisiac effects, Eurycoma can also increase sperm production and may directly act as a proerectile agent. At least one molecule in Eurycoma (9-hydroxycanthin-6-one) is associated with both a delay in ejaculation as well as pro-erectile properties (although the ability of this molecule to act via consuming Eurycoma extract is not known).
TESTIMONIAL
Tongkat Ali as a Potential Testosterone Booster
The active ingredients claimed to increase testosterone include steroidal saponins and eurycomanone. There’s also some aphrodisiac pro-erectile compounds in the herb such as Canthin-6-one metabolites and derivatives of Squalene.
Tongkat Ali has a huge reputation as a pro-erectile testosterone booster and if you’ve been reading any of the men’s health sites of the 20th century, you’ve had to stumble upon the herb few times by now…
a) The researchers at this randomized double-blind placebo study had 109 men as their test subjects. They gave half of these men 300 mg’s of freeze dried Tongkat Ali extract, and the other half got placebo. The abstract cites that the study went on for 6+ months.
The results showed that after 12 weeks there was significant increases in semen motility (+44%) and volume (+18%) in the Tongkat Ali Group. The test group also had significantly higher scores in the Erectile Function domain in (IIEF) questionnaire and noted significant improvements in libido when compared to the placebo group.
b) In this peer-reviewed study that appeared in the Journal of the International Society of Sports Nutrition 2013, the researchers had 62 moderately stressed subjects.
They gave half of their subjects a standardized hot-water extract of Tongkat Ali for the duration of 4 weeks, and the other half received a placebo.
The results showed that in the Tongkat Ali group there was significant improvements in tension (-11%), anger (-12%), confusion (-15%), cortisol (-16%), and testosterone (+37%).
Albeit this is the most promising study about Tongkat Ali so far, the effects would still need to be studied more on healthy men with no stress.
c) This study had 76 male subjects who suffered from late onset hypogonadism (low testosterone). The researchers gave these men 200 mg of a standardised water-soluble extract of Tongkat Ali for the period of 1 month.
The results showed a staggering 46% increase in total testosterone levels and remarkably 90,1% of the subjects were able to normalize their testosterone levels back inside the reference range.
d) Animal studies seem to show that Tongkat Ali has a pro-erectile testosterone boosting effect on rats.
