煮中药 (zhǔ zhōng yào) literally means 'to boil Chinese medicine' and refers specifically to the traditional process of decocting raw or dried herbal formulas in water over low heat for an extended period—usually 20 to 60 minutes—to extract medicinal compounds. The character 煮 means 'to boil' or 'to simmer', 中 indicates 'Chinese' (as in traditional Chinese medicine), and 药 means 'medicine' or 'herbal remedy'. Together, they form a compound verb describing a core therapeutic practice in TCM.

This process is typically done at home using a clay or stainless-steel pot, often following precise instructions from a licensed TCM practitioner regarding herb combinations, soaking time, boiling duration, and dosage. It’s distinct from simply brewing tea or taking pills—it emphasizes slow extraction, multiple rounds of decoction, and careful timing. While less common in Western medical contexts, 煮中药 remains widespread among people managing chronic conditions like fatigue, digestive issues, or seasonal illnesses using holistic care.
