How Chinese herbal medicine Gui Zhi Jia Hou Pu Xing Ren Tang Works
Gui Zhi Jia Hou Pu Xing Ren Tang is designed for weak individuals suffering from coughs, wheezing, or asthma, often linked to bronchitis or tracheal issues. These symptoms typically arise from an accumulation of dampness and heat in the body, which impairs lung function. Common signs include a thick tongue coating and sticky saliva, indicating damp-heat buildup.
In traditional Chinese medicine, damp-heat results from spleen and stomach imbalances, leading to phlegm accumulation that obstructs the lungs. This causes coughing, wheezing, and breathing difficulties. The formula works by:
Expelling Pathogens: Cinnamon twig and ginger induce sweating to clear external invaders.
Clearing Damp-Heat: Magnolia bark removes dampness and heat, improving symptoms like thick tongue coating.
Relieving Cough and Asthma: Apricot kernel directly soothes the lungs, easing coughs and wheezing.
By addressing both the root cause (damp-heat and lung dysfunction) and symptoms, the formula restores lung health and promotes easier breathing.
