Does Alangium salviifolium boost testosterone levels?
Alangium salviifolium is a tree that grows in India. Ayurvedic healers use almost all parts of the tree for medicinal purposes. They make an analgesic salve from the roots, which is also supposed to help leprosy.
The berries of the trees can stop bleeding and traditional healers in India use the tree's bark to induce abortion.
![]() Alangium salviifolium contains a huge number of bioactive ingredients, a few of which are shown below.
Researchers at the J.S.S. College of Pharmacy in India had heard that some local residents used bark extracts to reduce the libido of male dogs. This might mean that extracts of Alangium salviifolium bark may have an anti-androgenic effect. The researchers carried out an animal study to find out whether this is indeed the case.
The researchers made a methanol-based extract and gave male rats 10 or 20 mg per kg daily. The human equivalent of this dose is about 1.7 or 3.4 mg per kg bodyweight per day. These are interesting doses for supplements manufacturers.
The researchers administered their extracts orally every day for a week. One control group was given no active ingredients, and another control group was given daily injections of testosterone. Two experimental groups were given Alangium salviifolium injections supplemented with testosterone.
The researchers observed no anti-androgenic effects, but did notice androgenic effects.
At the end of the week it was clear that administration of Alangium salviifolium had led to an increase in size of the rats' testes. The effect of the extract on the rats' prostate and seminal vesicles was small – less than that of testosterone. There were no indications that the extract blocked the effect of testosterone.
So you might wonder: how could an extract like this reduce the sex drive of male dogs? Or did the researchers misinterpret things?
If you have such confusing information you'd probably want to find a study in which Alangium salviifolium really boosts testosterone levels, so that you'd be more sure of the testosterone-boosting properties of the plant. Unfortunately the researchers didn't measure testosterone levels.
There's no information on the label of Pro HD about the amount of Alangium salviifolium it contains. The supplement also contains a large amount of zinc, which you'd also expect to boost testosterone levels, plus an equally large amount of vitamin D3. Researchers suspect that vitamin D3 boosts testosterone levels.
And last but not least, Pro HD contains an unknown quantity of Paederia foetida, a climbing plant that an Indian animal study has shown to boost testosterone levels sufficiently to show a measurable anabolic effect.
