I had to do a paper for school about medicine in the early 1900’s. I could not believe some of the things that were commonly used to make patients vomit. I found an emetics list that included salt, warm water, alum, and mustard. Sometimes, copper sulfate was used. This was not as effective and usually had to be followed with a different emetic.
Adder’s tongue was also used as an emetic. The plant was made into a tea. Dogwood extract has also been used. I was also surprised to read that daffodil bulbs were used in a drink to induce throwing up.
