【古籍摘要】        1.《本草衍义》:“乌药和来气少,走泄多,但不甚刚猛,与沉香同磨作汤,治胸腹冷气,甚稳当。”       
 
2.《药品化义》:“乌药,气雄性温,故快气宣通,疏散凝滞,甚于香附。外解表而理肌,内宽中而顺气。以之散寒气,则客寒冷气自除;驱邪气则天行疫瘴即却;开郁气,中恶腹痛,胸膈胀痛,顿然可减;疏经气,中风四肢不遂,初产血气凝滞,渐次能通,皆藉其气雄之功也。”       
 
3.《本草求真》:“凡一切病之属于气逆,而见胸腹不快者,皆宜用此。功与木香、香附同为一类。但木香苦温,入脾爽滞,每于食积则宜;香附辛苦入肝胆二经,开郁散结,每于忧郁则妙。此则逆邪横胸,无处不达,故用以为胸腹逆邪要药耳。”
