Watermelon cream can treat pharyngitis. Watermelon cream belongs to Chinese medicine and is processed from the rind of unripe watermelon with this skin nitrate. The method of making it is to cut small openings in the raw watermelon, scoop out part of the flesh, put in the skin nitrate, also known as sodium sulfate, then cover the rind and air-dry it in a cool, ventilated place. When the skin nitrate oozes out to the outside of the watermelon, scrape the frost outside the skin to become watermelon cream. Its main function is to clear heat and fire, reduce swelling and relieve pain. It can be used for tonsillitis, pharyngitis, especially for the throat redness, pain, swelling and pain in the throat, mouth and tongue sores such patients are very effective. But in the process of using watermelon cream, pay attention to avoid spicy, fishy food. Patients with tonsillar suppuration and high fever should be treated with antibiotic medication at the hospital instead of relying only on this watermelon cream medication. In addition, children and pregnant women should use it under the guidance of a doctor.
