Epimedium grandiflorum (large flowered barrenwort, bishop's hat) is a species of flowering plant in the family Berberidaceae, native to China, Japan and Korea.[1] It is known as dâm dương hoắc in Vietnamese.
Description
It is a deciduous perennial growing to 30 cm (12 in), with bright red stems with green heart-shaped leaves (copper-tinged when young) which are slightly hairy on the bottom. In spring it produces pink, white, yellow or purple long-spurred flowers.[2]
Cultivation
Numerous cultivars have been selected for garden use, of which the following have gained the Royal Horticultural Society's Award of Garden Merit:
- E. grandiflorum[3]
- E. grandiflorum 'Nanum'[4]
- E. grandiflorum 'Rose Queen'[5]
- E. grandiflorum 'White Queen'[6]
Traditional Chinese medicine
E. grandiflorum may have anti-impotence properties due to the presence of icariin, a relatively weak inhibitor of PDE5 in comparison to substances like sildenafil (viagra). Western peer-reviewed research into the efficacy of E. grandiflorum as an aphrodisiac is lacking; however, the herb has been used for this purpose in traditional Chinese medicine and is a common ingredient of herbal remedies for impotence.[citation needed] It is commonly packed in a capsule with other ingredients or sold as herbal flakes or powder with the name "horny goat weed".[citation needed]
