Catuaba
There is little research to confirm that catuaba works the way it is reported to work. However, it has been used by Brazilian natives to treat low libido and erectile dysfunction for longer than history can document.
Sexual Function
The bark of a Brazilian tree, Catuaba contains the alkaloids catuabine A, B, and C, which are supposed to boost sexual function by stimulating the central nervous system. It reportedly calms the nerves, reduces nerve pain, and stimulates the memory.
Michael van Straten, a British herb researcher, claims that catuaba improves libido in both men and women and erectile dysfunction in men. He also reports that there are no side effects, even with long term use. He does not, however, support his claims with research evidence.
Other Benefits
Research has confirmed that catuaba has antimicrobial and pain-relieving properties. I’ve read several sites trying to sell Catuaba that claim it has full adaptogen properties. However, none of them reference their claims.
Many of the so-called ED or Prostate cures advertised claim they contain catuaba.
If you have ED and believe that it may be caused, at least in part, by nervous system problems or your ED is the result of emotional issues, you might want to try this herb.
Dosage
Catuaba works well with muira puma. It is available as a dried powder, extracts in capsules, and as a tincture. Brazilians drink three cups of tea per day.
Take 1 to 2 grams daily of the dried powder, or the equivalent based on the percentage of concentration of the capsules.
