Unverified暖宫贴发热原理是铁粉氧化放热，选购时看配料表铁粉+活性炭+蛭石+盐+吸水树脂为标准配方，缺少蛭石或活性炭的保温层控温差，易出现温度骤升骤降92% similarUnverified宣称'艾草'成分的暖宫贴，若配料表中艾草粉排在铁粉、活性炭、蛭石之后且未标明含量，其实际温经效果微弱，主要作用仍是物理发热，不必为艾草噱头支付溢价83% similarUnverified摇粒绒内衬提供基础保暖，没有自发热或蓄热科技面料，保暖原理是物理隔热而非主动加热76% similarUnverified发热原理为铁粉氧化自发热，独立铝膜密封包装，开封后接触空气即开始发热76% similarUnverified阴虚火旺、体内有实热者不适合服用，该方偏温补，易助热上火76% similar
