Cannabidiol (CBD) is a psychoactive cannabinoid found in cannabis. It is one of the most common cannabinoids in the plant, along with THC. CBD has a calming effect, but for some people it can generate a heightened concentration. In general, Indica strains of cannabis contain higher levels of CBD than Cannabis sativa.
CBD is effective against anxiety, muscular spasms, inflammation and nausea. Thanks to these qualities it can be used as a remedy or palliative for certain illnesses and disorders, a phenomenon known as medicinal use.
In certain countries a product called Savitex has been available since April 2005. Sativex is a ‘sublingual’ (for under the tongue) spray that contains THC and CBD, initially developed for people with multiple sclerosis.
The anti-psychotic effect of CBD reduces the symptoms of schizophrenia, as has been demonstrated by a study in which patients were given CBD orally over the course of four weeks.
