Plant dermatitis (also called ‘phytodermatitis’) is caused by reaction to skin contact with certain plants.
It is not always obvious which plant is responsible for a flare-up of the dermatitis (also known as eczema). Sometimes a rash may develop without direct contact with the plant; the juices may be on clothing or the fingers. A plant cause for dermatitis is suspected when there is a linear or streaky pattern. It is nearly always asymmetrical.
