“Cataplasma de mostaza: the Spanish mustard plaster. That one we do not do anymore: documented chemical burns.”
“Mosterdpap. Mustard flour and warm water to a paste on a cloth on the chest or a bad joint. That one we do not do anymore: documented second-degree chemical burns. Never on children, old thin skin, anyone asleep or numb, never more than a few minutes.”
