How can we treat the disease that lurks undetected in our body? Allergic asthma is a relatively stubborn disease that can last a lifetime if neglected. Most asthma patients have allergies or allergic rhinitis, and the onset of asthma in patients with allergic rhinitis may be preceded by sneezing, runny nose, itchy nose, itchy eyes, and watery eyes. The allergic cough like this patient is a pre-symptom of allergic asthma, which is diagnosed through a series of tests and treated before the attack, which is a reflection of our TCM idea of treating the disease before it occurs. The Yellow Emperor’s Classic of Internal Medicine says: “The upper work is to treat the untreated disease, not the existing one. The term “Shang Gong”, also known as “Great Doctor” and “Liang Gong”, refers to good doctors. The word “cure” means to govern and manage. “Cure” means to take appropriate measures to prevent the development of diseases. The main ideas in Chinese medicine are: prevention before illness and prevention after illness. Preventing diseases before they occur is important for health maintenance. The three main aspects are: to follow the natural way, to regulate the spirit and emotion, and to keep the Yin and Yang secret. Preventing changes after illness, as the name implies, is to treat illnesses in a timely manner and to anticipate the possible development of the disease in order to prevent further progress of the disease. After a period of treatment with Chinese herbs and creams, the patient not only lost the cough that had been bothering her for a long time, but also her lung function and IgE returned to normal after a review. The patient’s lung function and IgE returned to normal after the review.
