Yes Yohimbe can and worse if you combine certain others too.
i only posted the bare minimum of whats available and/or been suggested before..
It seems though (not just this forum) no matter what herbs get recommended the response is for Cialis, Levitra, or v1agra instead or some herbal blends with a lot more ingredients going on.
The point being of acquiring the individual herb, you CAN start gradually and make a better blend for yourself, rather than going whole hog and getting some very odd outcome.
