This plant is known as a "heart breaker" causing cardiac arrest for those who ingest the plants. However, it was also researched that the chemical component ibogaine has the potential to alleviate, if not eliminate, opioid addiction with little-to-no withdrawal side effects. Unfortunately, ibogaine has been labeled a Schedule I drug on a federal level, so studying its effects against opioids has been rather difficult.

Main Toxin

Molecular structure of ibogaine (PubChem)

Ibogaine

A psychoactive indole alkaloid that targets various neurotransmitter systems and neurotransmitters. Neurotransmitter systems include acetylcholine, dopamine, glutamate receptors, nicotinic receptors, NMDA, opoid receptors (kappa and mu), serotonin, and sigma-2 receptor sites. Ibogaine is considered to be a cholinesterase inhibitor as well as an inhibitor of oxidation of serotonin. Also targets hERG by blocking the gene in the heart. This causes the heart to be not be able to repolarize after a contraction in a timely manner. This delay causes arrhythmia and could result in cardiac arrest. One study has concluded that ibogaine is approximately 2.4 times more potent than its metabolite, noribogaine. Ibogaine metabolizes in the gut and liver into the metabolite noribogaine. Like the ibogaine, noribogaine targets hERG by blocking the gene in the heart. It is a contributor to long lasting effects after the consumption of the Tabernanthe Iboga
