Relationship between Icaritin and Icariin
Icaritin is the aglycone form of icariin — meaning it’s icariin without its sugar group. Specifically, icariin is hydroxylated at the 3- and 7-positions to form icaritin.
Both are the main active flavonoids found in Epimedium, a well-known herb in traditional Chinese medicine.
