“奔豚”作为病证名首见于《灵枢》，此后历代医籍则“奔　”、“奔肫”、“贵豚”、“贲　”、“贲肫”纷杂互用。本文通过考证辨明，“奔”音ｂｅｎ，义奔跑。“贲”为奔的通假字，音义和“愤”（ｆｅｎ）有别。“豚”音ｔｕｎ，“　”皆与其通假，义指小猪，部分医家把它释作江豚有失允当。 The “bao dolphin” was first seen in the “Lingshu” as the syndrome of disease, and the medical books in the later dynasties were confused and interdependent with “Ben”, “Benqia”, “Guiyang”, “Ben” and “Benxi”. This text discerns through the textual research, “Ben” sound ben, meaning runs. “Ben” is Ben’s fake word, sound meaning and “anger” is different. “Dolphin” sound tun, “” all with its pass, righteousness refers to pigs, some doctors interpreted it as a finless porpoise lost.
