Abstract: The paper compares the similarities and differences between Tang Zonghai's and Zhang Xichun's ideas on the treatment of hematemesis. Both of them attribute the cause of hematemesis to the adverse rising of qi and fire-heat, and the priority of treatment method is lowering the stomach qi to stop bleeding and should focus on eliminating blood stasis. However, Tang Zonghai (Tang) advocates eliminating blood stasis after stopping bleeding, while Zhang Xichun (Zhang) uses methods of eliminating blood stasis in the process of stopping bleeding. Besides, as to acute bleeding, Tang prescribes Dushen Decoction, while Zhang copes it with Daizheshi (haematitum) in addition to Dushen Decoction. Moreover, Tang establishes the method of soothing and tonifying blood, while Zhang makes good use of haematitum to treat sequela arising from blooding. It proposes that the exposition of Zhang enriches the content of Tang's four methods of treating blood patterns and can be a reference to modern clinical practice.
