针灸是中国古老的治疗方法，它的应用范围很广，可用于内、外、妇、儿、五官等300多种疾病的治疗和预防，治疗效果迅速，方法简便，没有或很少有副作用。
远古时期，中国人的祖先在劳动生活中发现，人的体表某一部位受到损伤后，身体的另一部位的疼痛就减轻或消失了，于是就用针灸等方法刺激体表某一部位，达到止痛治病的目的。
针灸理论是深奥的，中医认为人体的各个器官能够保持平衡，主要是靠经络的作用。经络是什么样子呢？人们看不见它，也摸不着它，但它是存在着的。经络主要有14条路线，这与现代测试技术得出的结果完全一致。中医认为经络是气血运行的通道，它内通脏腑，外联肢节，通行上下、前后、左右。气血聚集的地方就是穴位。经络很像城市中那纵横交错的公共汽车路线，穴位就像那一个个的汽车站，脏腑——经络——穴位就是这样紧密相联的。当脏腑等体内部位发生病变时，通过经络，与病变部位相联的穴位就会发生异常现象。如果刺激这些穴位，这种刺激就会传导到病变部位，使气血阴阳平衡，达到治病的目的。古今有许多事例，说明针灸的神奇疗效。
中国针灸著作也是很多的。西晋时皇甫褴根据《黄帝内经》等书，写了一本《针灸甲乙经》，这是一本非常重要的针灸学著作，书中详细记载了全身349个穴位和主治的疾病。明代杨继洲写的《针灸大成》，全面总结了明代以前针灸学的成就，对今天的针灸治疗还有指导意义。
针灸以它神奇的疗效赢得了人们的信赖，特别是中国针灸医生近年来创造的针刺麻醉，成功地应用在外科手术上，进一步引起人们对针灸的重视。如今，世界上的120多个国家和地区有了针灸医生。针灸疗法将为人类的健康做出更大贡献。
