Methylergonovine, also known as methylergometrine, methylergobasin, and d-lysergic acid 1-butanolamide, is a synthetic analogue of ergonovine, a psychedelic alkaloid found in ergot, and many species of morning glory. It is a member of the ergoline family and chemically similar to LSD, ergine, ergonovine, and lysergic acid. Due to its oxytocic properties, it has a medical use in obstetrics. According to Jonathan Ott, methylergonovine has LSD-like actions above 2 milligrams. Clinical dosages are ten times lower.
