Calabar Bean Overview
Calabar bean (Physostigma venenosum) is a plant that is native to West Africa. It is known for its bean-like seeds, which are poisonous and contain a toxic alkaloid called physostigmine. The beans have been used as a source for prescription drugs containing physostigmine, a cholinesterase inhibitor.
While Calabar bean has been used historically for its purported anti-inflammatory and pain-relieving properties, its use is generally not recommended as toxic effects can occur when ingested. These toxic effects can include excessive sweating, excessive salivation, nausea, vomiting, decreased blood pressure, confusion and muscle paralysis.
Naltrexone Overview
-
Naltrexone is used along with counseling and social support to help people who have stopped drinking alcohol and using street drugs continue to avoid drinking or using drugs. Naltrexone should not be used to treat people who are still using street drugs or drinking large amounts of alcohol. Naltrexone is in a class of medications called opiate antagonists. It works by decreasing the craving for alcohol and blocking the effects of opiate medications and opioid street drugs.
