Fumigation is an ancestral process used in herbal medicine, as well as by many civilisations and indigenous populations.
For example, in the American Indian tribes of the southwest coast of the United States, certain herbs such as white sage were used during religious ceremonies, births and also deaths to purify the atmosphere and "cleanse" a person of all negative waves and thoughts, but also to ward off the evil eye.
It involves the combustion of plants producing vapours charged with the active principles of the plant. Fumigation is practiced in a closed place so that the smoke can bathe the premises, then the smoke must be evacuated through a window.
