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.
If you're interested in rapid tests, your best bet is an STD clinic. You can call in advance to ask what rapid testing is available. Without rapid testing, STD test results may come back anywhere between 48 hours and two weeks. That's why you don't want to just ask how soon your STD test results will come back. It's also a good idea to ask your doctor whether they'll call with any results or only positive results.
