Mesembrine is an alkaloid present in Sceletium tortuosum (kanna). Mesembrine acts as a serotonin reuptake inhibitor. Mesembrine may contribute to the antidepressant effects of kanna. A study found it to be a potent inhibitor of phosphodiesterase 4 (PDE4)
Active ingredient: the indole alkaloid 'Mesembrine' http://www.freebase.com/view/en/mesembrine
IUPAC name
(3aS,7aR)-3a- (3,4-dimethoxyphenyl)- 1-methyl-2,3,4,5,7,7a- hexahydroindol-6-one

apparently its a bit like low dose mdma and seems to go very well with grass

My partner and I have both noted some similarities between Kanna and MDMA: in many ways, the Kanna high is like a very small dose of extremely clean MDMA. The empathogenic connection isn't nearly so strong, but neither is the tooth-grinding
Conclusion:
It may be concluded from the evidence presented that 'kougoed' and the Sceletium alkaloids show no hallucinogenic properties, but rather are narcotic-anxiolytic. This and their strongly synergistic interaction with other psychomimetics indicates a serious need for thorough pharmacological investigations. Foremost amongst these would be toxicity and mode of action, such as receptor binding. A recent study has shown that although mesembrenone was considerably less toxic to mouse fibroblasts that twenty-one amaryllidaceous alkaloids tested in vitro, it was moderately effective against cancer cells (Weniger et al., 1995).
According to the observations of plant gatherers, plants of Sceletium tortuosum and Sceletium strictum are becoming increasingly scarce. Dwindling natural populations point to possible overexploitation. A resurgence of interest in Sceletium alkaloids will serve to encourage cultivation of these plants, either in the natural habitat, botanical gardens, or elsewhere, especially as these taxa are reputedly easily grow

. Vesp do you know any species that contain both mesembrine and dmt? bet that would be quite the addition to an ayahuasca brew.
), noxious beyond belief to insufflate. He would bioassay the purified, recrystallized alkaloid fraction from S.tortuosum, working his way up from 1mg etc. Otherwise, he would sure enough add the plant to an entheogen garden, but the chances of him taking any are about the same as him taking a HNO3 enema, whilst sticking his cock into a wasps nest, pouring petrol over the entire thing, and flicking matches at random.
