Cinnamon comes from a tree. People use the bark to make medicine. Cinnamon bark is used for gastrointestinal (GI) upset, diarrhea, and gas. It is also used for stimulating appetite; for infections caused by bacteria and parasitic worms; and for menstrual cramps, the common cold, and the flu (influenza). Cinnamon bark, as part of a multi-ingredient preparation, is applied to the penis for premature ejaculation.
PPD skin test. The PPD skin test is a method used to diagnose silent (latent) tuberculosis (TB) infection. PPD stands for purified protein derivative. You will need 2 visits to your doctor's office for this test. At the first visit, the health care provider will clean an area of your skin, usually the inside of your forearm. You will get a small shot (injection) that contains PPD. The needle is gently placed under the top layer of skin, causing a bump (welt) to form. This bump usually goes away in a few hours as the material is absorbed. After 48 to 72 hours, you must return to your provider's office.
In this procedure a person is given a baseline PPD test. If the. test is negative, a second test is administered one to three weeks later. If the second test is. negative, the person is considered uninfected.
