[Textual research on diagnosis by lingual vessels].
Being a unique Chinese diagnostic measure, this method focussing its observation on the ventral vessels of the tongue, is first recorded in Neijing, saying that it is indicated when the vessels are varicose by puncturing for bloodletting in malaria, mad, and sadness. Ge Hong and Cao Yuanfan applied it for juandice, also for prognosis. Yimenfang predicts by this method the diagnosis for prognosis of the mother and foetus in difficult delivery, while Chen Zhiming popularized it in his Chan Nan sheng Si Jue. Inherited from the theory of Collateral Vessel Diagnosis, this approach pays attention to the observation of the forms and colors of collateral vessel, claiming that dark green color and congestion have bad diagnosis. Though not well developed, it was applied as extra-acupoints for swelling tongue, sore throat and jaundice. While Zhou Xuehai elaborated Liu Shouzhen's idea and put forward a theory of minute-vessel-stasis which is wonderfully conincided with modern microciroulation theory. In 1964, Zhang Zanchen again advocated its diagnostic value in tumor, hepatopathy and cor pulmonale.
