6-MeO-THH, or 6-methoxy-1,2,3,4-tetrahydroharman, is a β-carboline (or more specifically a pinoline) derivative and a structural isomer of tetrahydroharmine (7-MeO-THH). 6-MeO-THH is mentioned in Alexander Shulgin's book TiHKAL (Tryptamines I Have Known and Loved), stating that 6-MeO-THH is very similar to the other carbolines.[1] Limited testing suggests that it possesses mild psychoactive effects at 1.5 mg/kg and is said to be about one-third as potent as 6-methoxyharmalan.[2] It has been isolated from certain plants of the Virola family.
