Scientists say they’ve found the natural, side effect-free Viagra — and it’s called “horny goat weed.”

Researchers with the University of Milan released details of a study Monday. It indicates the old Chinese remedy — also known as epimedium — could perform the same magic as Viagra, without its undesirable side effects. They say the herb targets the same enzyme as the V-pill, only in a more direct (yes, DIRect) fashion. That could cut down on the headaches, stomachaches, and other potential problems that typically come along with Viagra use.

“Horny goat weed” has been used as an aphrodisiac for decades. This is the first time, the scientists say, it’s being expanded for — well, expansion-related purposes. The treatment is hard-ly ready for mass recommendation, though. More animal-based and human-specific tests are in the works to make sure the stuff really works as believed.
