This is an effective medicine when applied topically to the throat, sinus, gum, or open wound. The herbs fight inflammation both by invigorating qi and blood and clearing heat toxins (bacteria and virus). It is very good for sore throat, and can be effective against strep throat. The "frost" of the watermelon (Citrullus Xi Gua Shuang) is made by removing its contents and packing the hollow rind with salt. After a day or two a dark "frost" appears on the outside of the skin, which is scraped off. Another method uses an entire cut-up watermelon which is mixed with salt and put into a clay jar; the crystalline frost will seep to the exterior of the jar. --Jake Paul Fratkin - Chinese Herbal Patent Medicines
