Natural chemical 'beats morphine'. The natural chemical was able to relieve pain like morphine. The human body produces a natural painkiller several times more potent than morphine, research suggests. When given to rats, the chemical, called opiorphin, was able to curb pain at much lower concentration than the powerful painkiller morphine. The French team said their findings could be lead to new pain treatments.
Serotonin's presence in insect venoms and plant spines serves to cause pain, which is a side-effect of serotonin injection. Serotonin is produced by pathogenic amoebae, and its effect on the gut causes diarrhea.erotonin secreted from the enterochromaffin cells eventually finds its way out of tissues into the blood. There, it is actively taken up by blood platelets, which store it.
