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.
Diabetics are prone to boils because they have weakened immune systems. Boils are abscesses of infected skin that form near hair follicles. They are usually caused by bacteria â staphylococcus aureus â which can enter the skin through cuts. Boils tend to resemble pimples and are often yellow inside.
