Ginseng and Astragalus Combination addresses Kidney and Liver Yin deficiency with smoldering Heat affecting the Yin channels and organs. Heat due to deficiency can occur for a variety of reasons. When fever has depleted Yin, as often seen in the final stages of a warm-febrile illness, chronic fevers can recur and persist, with these most often experienced during the late afternoon and night and cooling by morning. Chronic disease, which injures the Liver and Kidneys, may manifest similar symptoms such as unremitting low-grade fever or tidal fever. (Kan Herb Company)*
