Purwoceng plus Pasak Bumi: the testosterone-boosting combo from Indonesia
Purwoceng or Pimpinella alpina is actually called Pimpinella pruatjan, and Purwoceng is sometimes spelled Purwaceng. Pasak Bumi or Tongkat Ali is officially called Eurycoma longifolia.
For their study the researchers used a combination of methanol extracts of both plants. They do not reveal the exact composition of the combination.
The researchers gave adult male rats a daily dose of 25 mg extract. The human equivalent of this dose would be about 1 g per day.
Before and after the supplementation period the researchers measured the concentrations of testosterone, LH and FSH in the animals' blood.
LH and FSH are hormones that stimulate the production of testosterone in the testes. The levels of these two rose by a minimal amount. The concentration of testosterone however rose by almost a factor 4. And that's not to be sneezed at.
In their article the researchers speculate about how the Pasak Bumi+Purwoceng combo might work. Perhaps worth taking with a pinch of salt, as the authors reasoning flies in the face of current biochemical knowledge. They believe that enzymes convert sterols in the herbal mixture into testosterone. But this reaction is impossible.
Moreover, the researchers also think that the herbal combo works partly because it boosts the synthesis of LH and FSH, while their data suggests that the components in the combination have a direct effect on the testes.
"From the above study, it is concluded that administration of buceng extract increase testosterone level which might enhance male vitality", the researchers write.
