《黄帝内经·灵枢·经脉》
像这些病，实症就用泻法，虚症就用补法，热症就用速刺法，寒症就用留针法，不实不虚的就从本经取治。
为此诸病，盛则泻之，虚则补之，热则疾之，寒则留之，陷下则灸之，不盛不虚，以经取之。
All these diseases, the substantive diseases should be treated with purgation therapies, the deficient diseases should be treated with replenishment therapies, the heat diseases should be treated with rapid needling, the cold diseases should be treated with prolonged needling, and the neither substantive nor deficient diseases should be treated from this channel.
