甘草是一种广泛应用的中草药，但其潜在副作用和与西药结合使用的安全性需要认真考虑。甘草中的主要成分，如甘草酸，经过体内代谢可产生葡萄糖醛酸和苷元甘草次酸[][]。葡萄糖醛酸具有解毒作用，而苷元甘草次酸则表现出肾上腺皮质激素类似作用。因此，与某些西药有相辅相成作用，但对于某些西药则相克相杀，能导致一系列不良反应，包括消化道溃疡、低血钾、水钠潴留、假性醛固酮症状等。虽然甘草运用广泛，也是常用药之一，但研究中发现，特别是对于具有消化道问题、高血压、心脏问题、糖尿病、风湿病等慢性疾病的患者，应慎重使用甘草。孕妇在怀孕期间的甘草摄入也需要谨慎。在中药与西药的联用时，医生应根据患者的具体情况制定合适的治疗方案，并密切监测患者的反应，以确保治疗的安全性和有效性。
