Fumitory (Fumaria Officianalis) has long been used for treating skin problems like scabies, eczema and acne. It has a bitter taste and is good for stimulating the liver and gallbladder. Culpeper has a long list of uses for fumitory including leprosy, jaundice, plague and pestilence! “The distilled water also…helps with all sores of the mouth and throat, being gargled often therewith.” Fumitory can be toxic in large doses. I’ve been eating small amounts, cut up finely, in my salads. The leaves and flowers can be used.
