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.
What Causes Boils in Children? Seeing a boil on your child can be shocking to a parent. Besides their ugly appearance, boils contain pus that's discharged with blood as the boil matures. As boils are highly contagious, caution must be used in cleaning one so the discharge doesn't touch unaffected areas of the skin. Because children are more active than adults, they're more prone to develop boils.
