205. Nastursium: i.e. watercress; hot and dry in the second degree; if it be boiled in water or with meat and eaten, it will clean the stomach and the respiratory organs of the cold humours. If it be boiled in wine and oil and eaten, it will help with stranguria and dysuria. If watercress be boiled in butter or oil and put on the navel, it will cure colic and ileus. If a fomentation be made of watercress for the anus, and its fumes be allowed to the anus, it will help with tenesmus; if it be applied hot to the navel, it will help with colic, as we have said.
