Epimedium (botanical name Epimedium grandiflorum) is a flowering plant belonging to the barberry family, called Berberidaceae. This species is indigenous to China, Korea and Japan. As this herb encloses icariin, it is likely to possess aphrodisiac attributes and it is considered to arouse sexual activity in goats - hence, its common name Horny Goat Weed. The plants of this species have vivid red stems and green leaves resembling the shape of the heart with some bristles on their underside. The herb normally grows up to a height of anything between 6 inches to 9 inches (15 cm to 23 cm) and bears pale purple hued blossoms in spring
