Incision of wounds and ulcers to be exposed

Galen says: The cut should be in the most protruding and thin place, and the cut should be directed in the direction where the pus can flow down. When making an incision, keep in mind the folds and wrinkles on the skin, in accordance with what we said in the paragraph about boils and ulcers, with the exception of the cases we mentioned, and in the groins and under the arms the incision should go along the natural folds of the skin. After the cut, put on the wound some medicine that dries without burning, from those mentioned in the sections of the Book of Simple Medicines. Crushed incense is better than whole incense, as it binds more strongly.

When treating wounds after an incision, it is correct to keep water away from them. If the patient cannot do without a bath and needs to be bathed, then the wound should be hidden under appropriate plasters, covering them with rags soaked in some oil so that they form a barrier between the wound and the bath dampness and water, or use some other a trick possible under the circumstances.
