The effectiveness time of Chinese herbal medicine for spleen and stomach weakness is related to the degree of spleen and stomach weakness, the accuracy of identification and other factors, and there are individual differences, which need to be analyzed on a case-by-case basis and cannot be generalized. First of all, the degree of spleen and stomach weakness is related to the length of the patient’s own illness. Most patients with short and acute illnesses recover quickly, and with symptomatic medication, the effect is obvious within a week or so after oral administration. For patients with chronic diseases of long duration, it takes at least 4 weeks of oral intake, and the time of effectiveness varies from person to person. Secondly, the effectiveness of oral herbal medicine is very much related to the accuracy of evidence identification. Patients with accurate evidence identification and mild spleen and stomach weakness may be effective after 1-3 payments of oral herbal medicine. In addition, the patient’s own cooperation is needed during the medication period. Many patients’ weak spleen and stomach are related to their poor living and eating habits, such as restful and less active, often eating cold, greasy and spicy food. Paying attention to improving these bad habits during the oral Chinese medicine will also be of great help in recovery.
