Pareira contains tubocurarine, an ingredient in modern intravenous (IV) anesthetics used to block nerve signals and paralyze muscles. However, very little, if any, of the tubocurarine in pareira gets absorbed into the body when taken by mouth. Some people might try to inject pareira into the bloodstream, but this is UNSAFE.
Special Precautions & Warnings:Pregnancy and breast-feeding: It's UNSAFE to use pareira if you are pregnant. It might start your menstrual period and cause a miscarriage.
It's also best to avoid pareira if you are breast-feeding. Not enough is known about how it might affect the nursing infant.
