A method and apparatus for the delivery of a vaporized pharmaceutical or medicant for the treatment and alleviation of ailments such as, cold symptoms, asthma, certain skin infections and/or for the delivery of medicants such as insulin, growth hormones, interferon and interlukin-2. A stream of air is heated and directed to the desired area and the medicant or pharmaceutical is vaporized into the air stream for delivery to the desired area. Preferably delivery is to the mucous or other mucosa membranes or to a desired localized area of application where it is absorbed by the body. In the treatment of colds the air is introduced into the nasal passages of the cold sufferer at a hyperthermia level. A vaporized microbicidal agent is introduced into the stream of air and into the nasal passages. The apparatus includes a housing containing a fan or blower and temperature control heating elements to warm the air. The housing includes a distribution area having outlets for positioning on or about the nasal area of the user or other body area so that the warmed air is directed to flow to the desired areas. A supply of microbicidal agent or other medicant within the apparatus housing is introduced into the flow stream of the heated air by a spray device so that minute droplets of the microbicidal agent or medicant are entrained within the flow stream of the heated air. The combined effect of the heated air at hyperthermia levels and the microbicidal agent or medicant act on the affected area or are absorbed into the blood stream for beneficial results.
