Can taking Liuwei Dihuang Pills cause constipation?

Taking Liuwei Dihuang Pills may potentially cause constipation, although the specific effects vary from person to person. 1. Constitutional factors: Some patients may be intolerant to certain components in Liuwei Dihuang Pills—such as Phellodendron bark (Huangbai) and turtle shell (Guiban)—which have astringent properties. This intolerance may slow intestinal motility and thus lead to constipation. 2. Dosage issues: Taking too high or too low a dose of Liuwei Dihuang Pills may disrupt intestinal function and subsequently trigger constipation. 3. Dietary factors: Consuming excessive spicy or irritating foods, high-fat foods, or large amounts of stimulating beverages such as strong tea or coffee while taking Liuwei Dihuang Pills may also impair intestinal motility and increase the risk of constipation. When taking Liuwei Dihuang Pills, it is important to follow medical advice and avoid self-medicating. Maintaining healthy dietary habits and lifestyle practices can help prevent constipation. If constipation occurs, prompt medical consultation is recommended.
