Chinese medicine description:

Qing Guo is sweet, sour and neutral in temperature. Qing guo is used for relieving toxicity such as infectious disease or even intoxication. It also generates fluids. In regard to infections there are aspects of both dampness and dryness. Dampness coagulates and hardens and dryness results in the tissues. Addressing dryness and coagulated dampness, by generating fluids, lubricates dry pathways to coagulated pathogenic areas. This assists the biochemical properties of other herbs to optimize their function. Generating fluids can also address lubricating organ, tendon, fascia, muscle, skin and other tissues that can become dry as a result of infections.78
