• Benefits the qi, generates fluids, and nourishes the yin:  for yin deficiency with heat signs and chronic, unabating fever.  Also for aftermath of a febrile disease with such symptoms as weakness, irritability, and thirst.*
• Nurtures the Lung yin and clears fire from the Lungs:  for Lung qi deficiency, which impairs the clearing and dispersing functions of the Lungs.  The primary manifestation is long-term wheezing and coughing up blood-streaked sputum.  Also for coughs, coughing up blood, and loss of voice due to Lung yin deficiency.*
