Re: bit of a technical question for ya all!
I used to take hawthrone ginko biloba for bp control, it did pretty well, trouble was the side affects were the same as beta blockers and ace inhibitors, it helped improve circulation but slowed my heart down and I couldn't exercise worth a hoot.
and I wasn't taking that much, not the amount suggested on the bottle I was taking maybe half and I still suffered these side affects I don't recommend hawthrone as a exercise tonic, it will slow you down, the ginko biloba might do better.
can't speak for the other herbs mentioned, I know with high bp I cant take genseng or some of the others. and as for helping build muscle, I doubt it, only exercise and strength training will do that, unless a person has high bp or some other vascular disease then these products are a waste of time money, and they still have side affects too. most do anyway.
