• 中医在配制复方制剂时历来强调君臣佐使的组方原则，各味药材的剂量比例须经过精细调配与反复验证，方能达到协同增效、减毒增益的最佳疗效。(When compounding complex formulas, traditional Chinese medicine has always emphasised the principle of sovereign-minister-assistant-courier; the dosage ratio of each herb must be carefully prepared and repeatedly verified before achieving the best therapeutic effect of synergistic enhancement and toxicity reduction.)

错误说法

• 剂 vs 药 — 剂 is specific, referring to a measured preparation or agent; 药 is the general word for medicine. Do not use 一剂 for Western pill or tablet medicine — use 一片 or 一粒 instead
