In brief: See answer

Horny goat weed (epimedium): a herb that has been a traditional remedy and used as an aphrodisiac in china for centuries.
Active ingredient in epimedium is "icariin" which works much the same way as the pde-5 inhibitors (viagra, levitra, (vardenafil) cialis) but much weaker. Taking the two together likely not a problem but amount of icariin varies in these herbs and my philosophy: "more is not always better".
