《黄帝内经·灵枢·官针》
病在皮肤浅表而游走不定的，当取用箭头形的镵针在病痛的所在处进行针刺，以泻除风热；但如果患部的肤色苍白而并无红肿充血的迹象，则说明热邪已去，就不能再取用镵针来进行治疗。
病在脉、气少、当补之者，取以鍉针于井荥分俞。病为大脓者，取以铍针。
Treat conditions affecting the superficial skin and which move around by puncturing the painful areas with arrow-shaped needles to dispel wind and heat. However, if the colour of the skin is pale without any sign of reddish swelling, this indicates that the evil heat has been eliminated and arrow-shaped needles should no longer be employed to treat the condition.
