Hua Shi, also known as Talcum or Talc Powder, is a sweet, bland, and cold mineral substance used in Traditional Chinese Medicine (TCM) to clear summer-heat, promote urination, and relieve damp-related symptoms. It is particularly effective for urinary difficulty, damp-heat diarrhea, and summer-heat conditions involving fever, thirst, and irritability. Due to its slippery and draining properties, Hua Shi is also applied externally for damp skin lesions and itching.
