Serapion, like our author, recommends applications which are moderately detergent, and neither very calefacient nor refrigerant. He gives the following directions for making a preparation from lime. Take of lime, seven times washed in sweet water and dried, oz. viij; of wax, oz. ij; of oil of roses, oz. vj: let the wax be melted along with the oil, and well mixed with lime. This is to be rubbed into the part. He also gives a prescription for preparing a mixture of lime-water and oil, exactly similar to that which is now used in cases of burns. (vii, 28.) Avicenna, with his usual accuracy, lays down very particular rules for the treatment of burns. To prevent blisters from rising he recommends cooling things; when the burning is occasioned by hot water, he directs us to apply sandals, rose-water, and camphor: or a cloth dipped in congealed water is to be kept constantly applied, and it will prevent blisters from rising. Most of the applications recommended by our author are also mentioned by him. Haly Abbas directs us to apply a cloth cooled in rose-water. He also speaks of the ointment of lime and rose-oil, mentioned above. When the burning is not severe, Alsaharavius directs us in the first place to wash the part with vinegar and salt, and then to sprinkle upon it the flour of barley or of oats. Then if blisters do not rise, but there is a sensation of burning in the part, he recommends us to apply cloths dipped in cold water, rose-water, or snow-water, which are to be changed frequently. Afterwards some emollient applications, such as the white of an egg, with gum arabic is to be used. When the burning is more severe, he recommends us to bleed and use a cooling application, such as the brain of a sheep, the white of an egg mixed with rose-oil, or an ointment made of white wax and rose-oil. He also makes mention of the application from lime. Rhases recommends an ointment containing ceruse, camphor, opium, &c. Like Avicenna, he directs us to apply at first a cloth wetted in cold water, or in rose-water, which has been cooled with snow. If the burning be extensive he recommends venesection, with a cooling and attenuant diet. When the pain is great he directs us to apply the yelks of eggs mixed with rose-oil. When a large ulcer is formed, he directs us to dress it with the ointment of lime, described above. He also approves of a white ointment, consisting of ceruse, oil of roses, and wax. In his ‘Continens,’ he relates a case of severe burning, which he treated with liniments composed of sandals, camphor, and roses; a cloth wetted in snow-water being applied externally to it. He approves of opening the blisters. To prevent them from forming, he recommends strongly an astringent collyrium of galls. Like many of the other authorities, he recommends Cimolian earth very much. The applications recommended by Haly Abbas are of a refrigerant and cooling nature, such as Armenian earth in vinegar, the white of an egg, ceruse, &c.
