Paragraph 2: History and Principles of Formulation

Poria Pills were first seen in the "Taiping Huimin Hejiju Prescription" of the Song Dynasty, and its prescription reflects the traditional Chinese medicine theory of "treating dampness first and regulating qi". The core medicinal material Poria cocos is used as a monarch medicine to induce water and dampness (accounting for 40%), Pinellia ternata is a ministerial medicine for drying dampness and resolving phlegm (accounting for 30%), it is supplemented with Citrus aurantium to promote qi and widen the middle (accounting for 20%), and ginger is used to harmonize the spleen and stomach (accounting for 10%). Modern pharmacological research shows that the Poria polysaccharide in this prescription can regulate intestinal flora, and the alkaloids in Pinellia ternata have antitussive effects, which is mutually confirmed with the effects recorded in "Prescriptions of Traditional Chinese Medicine".

Paragraph 3: Analysis of applicable symptoms

According to the clinical guidelines of "Internal Medicine of Traditional Chinese Medicine", Fuling Pills are mainly suitable for diseases with phlegm-dampness obstruction. Typical manifestations are: excessive phlegm in the morning, chest tightness, epigastric swelling, and white and greasy tongue coating. Professor Wang Qingguo of Beijing University of Chinese Medicine pointed out in "Clinical Application of Classic Prescriptions" that this prescription has an auxiliary regulatory effect on chronic bronchitis, functional indigestion and other diseases. Special attention should be paid to it, it should not be used by those with yin deficiency and dry cough, and pregnant women should use it under the guidance of a physician.

Paragraph 4: Modern application extensions

In recent years, clinical observations have found (data source: China Journal of Traditional Chinese Medicine 2022) that modified Fuling Pills can improve patients with metabolic syndrome. A controlled study of 120 cases conducted by the Guangdong Provincial Hospital of Traditional Chinese Medicine showed that with lifestyle intervention, the waist circumference of the experimental group was reduced by an average of 3.2cm, which was better than the lifestyle group alone. This confirms the conclusion of Ye Tianshi, a famous doctor in the Qing Dynasty, that "phlegm-dampness is the mother of all diseases." However, it must be clear that this prescription cannot replace basic treatments such as lowering blood pressure and lowering blood sugar.

Paragraph 5: Summary and reminder

Poria Pills is a classic prescription that has been proven for thousands of years. Its core effect of removing dampness and reducing phlegm has been partially confirmed by modern medicine. Treatment should be based on syndrome differentiation when used. It is recommended to adjust the compatibility according to individual constitution under the guidance of traditional Chinese medicine practitioners in regular medical institutions. Remember that traditional prescriptions take a long time to take effect and generally need to be taken continuously for 2-4 weeks before the effect can be evaluated. Store in a cool and dry place to avoid decomposition of active ingredients.
