229. Plumbum: i.e. lead; it is cold and wet; it has the virtues of repercussing and cooling. If a thin plate be made of it and put on the parts of the body where there is excessive heat, it will help with them. To reduce the discharge from and inflammation of wounds, and to dry them, a surgical tent of lead may be put in the wound, or a thin plate with many holes in it may be put on the opening, outside, and this will greatly relieve them. To stop infection arising from a burn of fire or water, a plate of lead may be applied to it externally.
