我不是医药专业，所谓“西药”，就是“中药”的分析成分后，提纯后的化合物

Medicines have been made from natural sources like plants, herbs, roots, vines, and fungi since ancient times. In the Middle Ages, medicines were made from herbs, spices, and resins. As science advanced, chemists were able to extract active ingredients from natural sources to create more potent medicines. For example, aspirin (acetylsalicylic acid) comes from the willow tree, which has been used in traditional herbal remedies.

西药就是西方人从植物，矿物，菌类里提炼出有效成分做成的。

中药就是还停留在比较原始的未提炼的原生状态。

所以，我认为，西药应该更安全更有效（当然还是具有副作用）。中药里杂质会比较多。
