7-Hydroxymitragynine (7-OH) is a terpenoid indole alkaloid from the plant Mitragyna speciosa, commonly known as kratom. [2] It was first described in 1994 [3] and is a human metabolite metabolized from mitragynine present in the Mitragyna speciosa. 7-OH binds to opioid receptors like mitragynine, but research suggests that 7-OH binds with greater efficacy.
In Thai varieties of kratom, mitragynine is the most abundant component (up to 66% of total alkaloids), while 7-hydroxymitragynine (7-OH) is a minor constituent (up to 2% of total alkaloid content). In Malaysian kratom varieties, mitragynine is present at lower concentration (12% of total alkaloids). [ 5 ]
Mitragyna speciosa is a tropical evergreen tree of the Rubiaceae family (coffee family) native to Southeast Asia. [3] It is indigenous to Cambodia, Thailand, Indonesia, Malaysia, Myanmar, and Papua New Guinea, [4] where its leaves, known as kratom, have been used in herbal medicine since at least the 19th century.

Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
(This was a total dose; many regimens called for three doses daily over three days, and the "three teaspoons three times a day for three days" regimen was typical around the 1950s when use of santonin was starting to wane; actual doses per dose were closer to 20–30 milligrams per adult dose in a typical "'50s regimen", but "one-shot" doses of ...
[40] [page needed] 2C-B is both a psychedelic and a mild entactogen, with its psychedelic effects increasing and its entactogenic effects decreasing with dosage. 2C-B is the most well known compound in the 2C family, their general structure being discovered as a result of modifying the structure of mescaline.
Ether extracts about 1–7% of the dried leaf mass. [27] Vachellia sieberiana, DMT, in the leaf [9] Acacia simplex, DMT and NMT, in the leaf, stem and trunk bark, 0.81% DMT in bark, MMT [9] [43] Vachellia tortilis, DMT, NMT, and other tryptamines [33] Acacia vestita, Tryptamine, in the leaf and stem, [9] but less than 0.02% total alkaloids [15]
MET has been briefly mentioned in Alexander Shulgin's TiHKAL (Tryptamines I Have Known and Loved) and other publications, where he has stated it to be orally active as a psychedelic at doses of 80 to 100 mg. [1] [2] The freebase of MET is active as a psychedelic via vaporization at a dose of 15 mg per a 2011 Erowid trip report. [6]
