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.
Skin abscesses, also known as boils, are more common in people with uncontrolled diabetes. They are usually caused by bacteria, typically Staphylococcus aureus or Streptococcus, but the abscesses can also be caused by other bacteria. For example, MRSA (methyl-resistant Staph aureus) is a dangerous bacteria that can initially look like a boil. It is important that the boils be evaluated by a health care provider and the right antibiotic prescribed. You can develop blood infections from untreated abscesses.
