Pilocarpine
Pilocarpine is a naturally occurring alkaloid that is extracted from plants of the Pilocarpus Rutaceae. Pilocarpine stimulates the parasympathetic nervous system, causing an increase in saliva, urine and sweat production.
Examples: The sweat test, used for diagnosing cystic fibrosis, is performed by using an electrode filled with pilocarpine. The electrode is placed on the inner forearm, and a second electrode is placed on the outer forearm. A current is run through the electrodes delivering the pilocarpine under the skin.
