根据前人学说,中风有外风和内风之分。例如《伤寒论》太阳篇所载:“太阳病、发热、汗出、恶风、脉缓者名为中风”。这种中风,是中于外来之风,应呼之为外风。至于猝然昏倒,痰涎上涌、牙关紧闭、半身不遂,这种中风、又名猝中,应呼之为内风。以下专谈所谓“内风”的中风病症。查中风一症,前人议论纷纷,莫衷一是。 According to previous theories, stroke has the distinction between external wind and internal wind. For example, “Treatise on Febrile Diseases” contained in the Sun article: “Son-phobia, fever, sweating, evil wind, and pulse are called stroke ”. This kind of stroke is a foreign wind and should be called an outside wind. As for the fainting of fainting, the ups and downs, the tightness of the jaws, and the half-length of the body, this kind of stroke, also known as squatting, should be called an inward wind. The following talks about the so-called “inside wind” stroke disorder. After investigating the syndrome of stroke, the predecessors debated and could not agree.
