Aerosol ointment compositions are provided that, when a deposit is expelled from an aerosol container onto damaged tissue, there is applied to said tissue a cold ointment by which exerts a cooling pain relief effect and a medicinal therapeutic effect on said tissues. Exemples of typical ointments of the invention are those for the temporary relief of hemorrhoids, treatment of sunburn and relief from arthritic pain. A method for the manufacture of aerosol ointment composition capable of expelling from aerosol containers ointments that exert on damaged tissues both a pain relieving cooling effect and a medicinal therapeutic effect. The aerosol compositions that enhance the therapeutic action of an ointment by instantly producing a sustained cooling effect which provides fast relief from pain and itching as well as a tendency to shrink swollen, inflamed tissue in advance of the slower action of any medication present in the ointment, where the aerosol composition consists of from about 10 to about 60 percent by weight of an ointment component and from about 40 to about 90 percent by weight of liquefied propellant that is predominantly a non-polar propellant, and where the sum of the ointment component and the propellant equals 100 percent by weight of the composition.
