Toxicodendron radicans, commonly known as eastern poison ivy or poison ivy, is a poisonous Asian and North American flowering plant that is well known for causing an itching, irritating, and sometimes painful rash in most people who touch it, caused by urushiol, a clear liquid compound in the plant's sap.
Boil: Introduction. A boil is a large infection of a hair follicle, the tiny opening in the skin from which a hair grows. Boils are due to an invasion of bacteria that enter the follicle and cause a bacterial infection of the follicle and nearby skin. Boils are also called skin abscesses or furuncles.
Boils (also known as furuncles or carbuncles) are tender, red lumps that may ooze pus. A single boil may be due to a ruptured cyst or a small abscess. Most boils can be treated by incision and drainage, a minor surgical procedure to open the boil and to drain the pus. Oral antibiotics are usually not needed. Some people have multiple or recurrent boils, which are usually due to Staph infections.
