A Dorsale Plaister.
Take Rupture Plaister, Diapalma, each as much as you please, and melt them together.
It's for Pain and Weakness of the Back, and the Fluor Albus. Applications are made to the Loins in these Cases, not because the Kidneys are there situated, but because the Arteries that bring the Blood to the Pudenda, issue out of the Aorta at this place. And also because of the relaxed Muscles and Ligaments of the same part.
