[Cannabinoids in the control of pain].

Hemp (Cannabis sativa L.) has been used since remotes ages as a herbal remedy. Only recently the medical community highlighted the pharmacological scientific bases of its effects. The effectiveness of the cannabinoids in the treatment of nausea and vomit due to anti-neoplastic chemotherapy and in the wasting-syndrome during AIDS is recognized. The good ratio between the polyunsatured fatty acids omega-3 and omega-6 of the oil of Cannabis seeds led to reduction of the phlogosis and an improvement of the pain symptoms in patients with chronic musculo-skeletal inflammation.
