Q. Can I take my usual medications or supplements while on diet herbal medicine?

I understand your concern—many patients wonder if they can continue their daily supplements or prescription drugs like blood pressure or diabetes medications while taking herbal medicine for weight loss. The answer is: it depends. On the positive side, herbal formulas can sometimes enhance nutrient absorption or mitigate side effects of Western drugs. For example, in cases of Spleen Deficiency (脾虛, bi xu) with poor digestion, reinforcing the Spleen with herbs may stabilize blood sugar‑lowering drug absorption. Some supplements may even complement the herbal formula’s effects. However, risks cannot be ignored. Certain herbs affect the CYP450 enzyme system, which can raise or lower blood levels of drugs metabolized by the same pathway (e.g., warfarin, statins, antidepressants). Additionally, minerals or alkaloids in herbs may bind to iron supplements or thyroid medications, reducing their absorption. Omega‑3, vitamin K, and ginkgo biloba, in particular, may increase bleeding risk when combined with specific herbs. That is why I always advise patients to bring a complete list of all medications and supplements before receiving a prescription. Because TKM herbal formulas are individually tailored to one’s constitution and condition, your doctor can adjust the formula or dosing schedule—for instance, separating intake times or omitting certain herb components—after consulting with a pharmacist. Please never self‑judge; always make decisions together with a qualified professional.
