According to the thinking of dialectical medication in traditional Chinese medicine, Dendrobium candidum or Dendrobium candidum is suitable for all kinds of heat syndrome. But people's constitutions are different, and not everyone is a heat syndrome. Therefore, the application of Dendrobium candidum or Dendrobium candidum varies from person to person, and not everyone is suitable for dialectical application. According to Zhao Xuemin's Compendium of Materia Medica, Dendrobium is only suitable for those with stomach deficiency and heat, but not for those with weak fire. Do not use it for those with spleen deficiency and dampness, and those with cold constitution.
Traditional Chinese medicine has the method of clearing heat and nourishing yin, and the bitter cold Dendrobium nobile and Dendrobium pili also have the function of clearing heat and nourishing yin.
