The Plants That Can Cause Skin Irritation
There are several ways in which a particular plant can cause skin allergies and irritation. Some plants have sharp thorns, fine hair or bristles which can prick the skin and lead to rashes and inflammation. When the skin comes in contact with the sap or juices of certain plants, it can lead to skin irritation. Plants that cause skin irritations can be divided into five broad categories. The first is poison plants, that carry a toxin known as urishiol in their sap. Coming into contact with these plants causes rashes and blisters on the skin. The most common poison plants are poison ivy, poison oak and the sumac tree. Allergenic plants, on the other hand, do not affect everyone that comes into contact with them. However, they can trigger severe allergic reactions like asthma and hay fever in some people. Examples are orchids, tulip bulbs, chrysanthemums and dahlias.
Some common skin irritants are poinsettias, pencil trees, daffodils, hyacinths and buttercups. Less serious are the stinging plants that cause only temporary toxic reactions when their nettles are touched. And lastly, scratches from seemingly innocuous thorn plants like roses, berry bushes, and black and honey locust trees can also inflict a severe infection.
