Dioscorides, Avicenna, and Galen, agree in praising Cimolian earth as an application to recent burns. Galen says that copperas, especially when dissolved in vinegar, forms an excellent application for the ulcers occasioned by burning. Aëtius treats burns upon nearly the same principles as our author. When blisters rise he forbids an early opening to be made in them. As an application to them he recommends alum with water and the white of an egg. Some of his applications can only be supposed proper for the foul ulcers left by burning. Such is that consisting of verdigris and litharge, pounded with wine and oil. For healing ulcers he recommends a composition containing ceruse, litharge, toasted barley pounded, wax, and rose or myrtle oil. In the ‘Euporista’ Cimolian earth, litharge and oil, and many other applications are recommended. Actuarius recommends a composition of litharge, ceruse, wax, turpentine, and some other articles of less importance. We need scarcely mention how much the oil of turpentine has been used of late in such cases. He praises such things as are moderately astringent, such as alum dissolved in vinegar, &c. Celsus recommends at first such things as are, “mediocriter exedentia reprimentiaque,” and afterwards articles of a soothing nature. To the former class belong the farina of lentils and honey; myrrh with urine, or the Cimolian chalk, with the bark of frankincense; and to the latter belong all fatty applications, and such things as contain the dross of lead and the yelks of eggs. He also mentions turpentine rosin, as an application to foul ulcers from burning.
