Wheat dermatitis

This disease is also called wheat dermatitis, and it is commonly known as barley or wheat poison. It is a common skin disease during wheat harvest. After contacting the ears of wheat, you first feel the symptoms of local itching on the skin. On the same day or a day later, a few scattered red needles or erythema of the size of the millet occurred at the contact site, often accompanied by scratches and itching.
