At last! A satisfactory Epsom Salts rub MAG. SULF. RUB (Upsher Smith) (Glycerite Mag. Sulf.) For Sprains, Bruises, Sore Tendons and other external injuries. A concentrated solution of Epsom salts, sus- pended in a lubricating base, penetrating, drawing, soothing, cooling, but will not blister. Ready for immediate use. Trainers have long valued the healing prop- erties of Epsom salts in the treatment of local injuries, using wet packs of the solution. Only a small portion of the salts at best comes into action when applied in this way. In order to improve on this method a series of experiments was undertaken with the object of combining the Epsom salts with a lubricant, in order to secure thorough penetration of the remedy into the injured tissues. After scores of trials, in collaboration with an ex- pert trainer, this improved product, Mag. Sulf. Rub (Upsher Smith) was pronounced perfect. Always ready for instant use TE
