Dilong is a traditional Chinese medicine with the effects of clearing heat and removing toxins (removing heat and toxins from the body), promoting blood circulation and activating blood circulation, while brown sugar is a food. Clinically, Dilong plus brown sugar can be used in the treatment of decubitus ulcers, pediatric thrush and burns. However, whether Dilong plus brown sugar has the effect of treating the above diseases needs to be consulted with a professional doctor. The source of Dilong is the dried body of the giant earthworm, the common earthworm, or the pecten-blind earthworm, etc. It is salty in taste and cold in nature, and has the effects of clearing away heat, calming asthma, clearing the channels, and inducing diuresis, etc. It can be used in the treatment of high fever and fainting, convulsions of eclampsia, lung-heat asthma and coughing, paralyzing pain in the joints, numbness in the limbs, and oedema and urinary problems. As a traditional Chinese medicine, Dilong should be used under the guidance of a physician’s diagnosis, and should not be used blindly on its own with brown sugar, so as not to adversely affect the body, and should be used with caution by people with a weak spleen and stomach (spleen and stomach weakness and cold).
