Practitioners of complementary and alternative medicine (CAM) frequently claim that modern medicines are synthetic, causing more harm than benefit to patients, and that natural products are safer and provide healing. However, it should not be forgotten that many current medications are actually derived from natural sources such as plants and marine products, and are developed through a rigorous process involving numerous different testing stages, including meticulous laboratory tests and clinical trials. Drugs proven effective and safe are made available for use after being approved by international authorities. It is observed that complementary and alternative medicine practices do not undergo these comprehensive scientific processes. Furthermore, the risk that some herbal products may interact with chemotherapy drugs, potentially reducing treatment efficacy or increasing side effects, leading to serious adverse outcomes, should not be overlooked. Therefore, if you are considering or using complementary or alternative treatment methods, it is crucial to consult your doctor to prevent potential risks and drug interactions.
