Horse mint and palm of crystal (castor-bean) and bullnettle root boiled together will make a cure fer swelling.
Some genera like the castor-bean (Ricinus) and Croton are cultivated for their large, showy leaves.
"Why, it's only what we call the castor-bean, only this is larger," I venture to say.
The castor-bean and tobacco-plant are also often seen carpeting the ground with emerald.
This resemblance is responsible for some of the popular names, such as "castor-bean tick," etc.
