herbal supplementation
"I am 64 I am in very good health but at this age I can not sustain my erection a sufficient time . So I tried 3 kinds of GINSENG   I had a very strong and sustained erection. But unfortunately 2 times I get for 2 days high blood pressure until 17/11  and the 3rd time I get a big allergy with muscle shaking and blood pressure raising quickly  I stop it. So I don't  dare take it any more. Is there a solution ?"
