Epimedium is a plant category, not a single standardized dose
“Horny Goat Weed” commonly refers to Epimedium species. Marketing often focuses on icariin and blood-flow-related mechanisms, but laboratory or animal findings do not establish a reliable human sexual-performance outcome.
HorseWood label context
A published HorseWood label page listed 8 mg of a 10:1 Horny Goat Weed extract, described as roughly 80 mg dried-herb equivalent. That does not state an icariin standardization, so a comparison to an icariin-standardized product would require more information than the herb name alone.
Practical label question
Ask whether the manufacturer discloses species, extract ratio, standardization and testing. If it does not, avoid inventing precision from a generic “equivalent milligrams” number.
