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. [5]
But some estimates put the toll far higher: An analysis by The Washington Post found kratom listed as the leading or partial cause of death in at least 4,100 deaths from 2020 to 2022, and an ...
Mitragynine is an indole-based alkaloid and is one of the main psychoactive constituents in the Southeast Asian plant Mitragyna speciosa, commonly known as kratom. [4] It is an opioid that is typically consumed as a part of kratom for its pain-relieving and euphoric effects.
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.

(+)-Desmetramadol is a G-protein biased μ-opioid receptor full agonist. [5] It shows comparatively far lower affinity for the δ-and κ-opioid receptors. [6] The two enantiomers of desmetramadol show quite distinct pharmacological profiles; [7] both (+) and (−)-desmetramadol are inactive as serotonin reuptake inhibitors, [8] but (−)-desmetramadol retains activity as a norepinephrine ...
Because of this, dextromethorphan polistirex takes considerably longer to absorb, resulting in more gradual and longer lasting effects reminiscent of time-release pills. As a cough suppressant, the polistirex version lasts up to 12 hours. This duration also holds true when used recreationally.
