Horny goat weed, or epimedium, is an ornamental herb from Asia and the Mediterranean. It is traditionally used as a libido booster. There is little research concerning how horny goat weed works, although Dr. Ray Sahelian, author of "Natural Sex Boosters," believes that the herb increases neurotransmitters that may affect hormones and has flavonoids that enhance nitric oxide formation, which usually leads to better erections. Both men and women may use the herb to increase libido. Consult your doctor before taking horny goat weed.

Take between 250 to 500mg of horny goat weed each day with water. There is no standard clinical dosage of the herb, but Sahelian has found that his patients experience quick results with this dosage range.

Take a weeklong break for each month that you are taking horny goat weed.

Adjust your dosage depending on the results you get. Some users find that they experience results within the first week of use. Some find that their results are minimal.
