Traditional Chinese medicineE. 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|date=January 2016}} It is commonly packed in a capsule with other ingredients or sold as herbal flakes or powder with the name "horny goat weed".[8]References1. ^1 {{GRIN | accessdate=2010-05-25}} 2. ^{{cite book|title=RHS A-Z encyclopedia of garden plants|year=2008|publisher=Dorling Kindersley|location=United Kingdom|isbn=1405332964|pages=1136}} 3. ^{{cite web | url= https://www.rhs.org.uk/plants/pdfs/agm-lists/agm-ornamentals.pdf | title = AGM Plants - Ornamental | date = July 2017 | page = 35 | publisher = Royal Horticultural Society | accessdate = 6 February 2018}} 4. ^{{cite web|title=RHS Plant Selector - Epimedium grandiflorum|url=http://apps.rhs.org.uk/plantselector/plant?plantid=2862|accessdate=18 June 2013}} 5. ^{{cite web|title=RHS Plant Selector - Epimedium grandiflorum 'Nanum'|url=http://apps.rhs.org.uk/plantselector/plant?plantid=2863|accessdate=18 June 2013}} 6. ^{{cite web|title=RHS Plant Selector - Epimedium grandiflorum 'Rose Queen'|url=http://apps.rhs.org.uk/plantselector/plant?plantid=699|accessdate=18 June 2013}} 7. ^{{cite web|title=RHS Plant Selector - Epimedium grandiflorum 'White Queen'|url=http://apps.rhs.org.uk/plantselector/plant?plantid=5511|accessdate=18 June 2013}} 8. ^{{Cite web|url=https://www.webmd.com/vitamins-supplements/ingredientmono-699-horny%20goat%20weed.aspx|title=HORNY GOAT WEED: Uses, Side Effects, Interactions and Warnings - WebMD|website=www.webmd.com|language=en|access-date=2017-10-20}} External links
