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 are eruptions on the skin caused due to bacterial infection. They usually affect hair follicles and can cause severe pain. Boils can appear anywhere on the body, but are most commonly seen in areas where there is more perspiration, such as the armpits, face and buttocks. Boils start as tiny red eruptions, and slowly enlarge in size as they get filled with pus.
