Neurotransmitters are compounds that see to for the transfer of nerve stimulus between cells of the nervous system. These alkaloids influence thus also the transfer of nerve stimulus in the brain. Other alkaloids grab at transport over the cell membrane, the protein synthesis, or on particular enzymes.

The first plant alkaloid morphine from Opium became discovered in 1803 by the pharmacist F. W. Sertürner and with that put the foundation for alkaloid chemistry. Often come in the plants next to a main alkaloid different side alkaloids, by which the main alkaloid has not however only the function of all of them together. Most alkaloids have a strong effect on the nervous system, work soothing, against cramps, partly anesthetizing, sometimes promoting blood circulation (Mistletoe) or bleeding stopping (Ergot).
