The Messini method suggests the heating of the territories of the nasal cavities, of the areas of the frontal and maxillary sinuses, followed by the jaws with open mouth, subsequently of right and left ear, finally the right and left lateral cervical region.

The procedure should be performed at least two to four times daily for at least two minutes, over the whole cold season. In epidemic periods it should be repeated several times a day.

Such treatment can contrast the ”vital” and replicative biological capacities of the ”cryophilic” viruses.
