Tetterwort; Greater Celandine

The latex could be employed as a caustic for healing small open wounds. Early studies of celandine showed that it causes contact dermatitis and eye irritation, particularly from contact with the poisonous red to yellow latex sap of the stem. This effect has not been observed in animal studies; no inflammation was observed in rabbit eye tests. The latex can leave a non-permanent stain. Stains on skin of the fingers are sometimes reported to cause eye irritation after rubbing the eyes or handling contact lenses. When any part of the plant causes eye irritation, wash it out with clear water and when needed seek medical help. The latex is also known to stain clothes.
