以春甲乙伤于风者为肝风，以夏丙丁伤于风者为心
风，以季夏戊己伤于邪者为脾风，以秋庚辛中于邪者为肺风，以冬壬癸中于邪者为肾风。
人身与天地气化相通，五脏合五时之气候，风为天气，故以天干之五行而应五脏也。
风中五脏六腑之俞，亦为脏腑之风，各入其门户，所中则为偏风。
五脏六腑，皆有俞穴在背，为脏腑之门户。风中于俞，由一门而入，邪止偏入一脏一腑，故名偏风也。
风气循风府而上，则为脑风；风入系头，则为目风，眼寒；饮酒中风，则为漏风；入房汗出中风，则为
内风；新沐中风，则为首风；久风入中，则为肠风飧泄；外在腠理，则为泄风。故风者，百病之长也。至其
变化，乃为他病也，无常方，然致由风气也。
督脉风府穴，上通于脑，而又通太阳经，太阳经脉起于目内 ，故风由风府而上入于脑，则头脑痛，由太
阳而至目 ，则为眼寒也；饮酒之人，多汗而腠理疏漏，风邪易入，故名漏风；入房汗出，风邪乘虚入内，故
名内风；新沐阳气发泄，头为诸阳之会，故风中于首也；久风入于腑，则为肠风飧泄者，食不及化而下泄，
以风性疏利故也。诸邪伤人，必由于风，故风为百病之长。至其变化，乃为他病，而无常方，然其致病，总由
风气也。
In the spring, on Jia and Yi days, contracting wind pathogen is termed Liver Wind (Gan Feng); in summer, on Bing and Ding days, contracting wind pathogen is termed Heart Wind (Xin Feng); in late summer, on Wu and Ji days, contracting evil pathogen is termed Spleen Wind (Pi Feng); in autumn, on Geng and Xin days, contracting evil pathogen is termed Lung Wind (Fei Feng); in winter, on Ren and Gui days, contracting evil pathogen is termed Kidney Wind (Shen Feng).
The human body communicates with the Qi transformation of heaven and earth; the Five Zang organs correspond to the climatic conditions of the five seasons. Wind belongs to heavenly Qi; therefore, the Five Elements of Heavenly Stems correspond to the Five Zang organs.
When wind pathogen invades the Shu points (Back-Shu acupoints) of the Five Zang and Six Fu organs, it becomes Wind of the Zang and Fu organs. Entering their respective gates, the affected area is named Pi Feng (Hemiplegic Wind or Asymmetric Wind).
The Five Zang and Six Fu organs all have Shu points located on the back, which serve as the gates of the Zang and Fu organs. When wind pathogen enters through these Shu points, it enters via one gate, and the evil pathogen only penetrates asymmetrically into one Zang or one Fu organ; hence it is named Pi Feng.
Wind Qi follows the Fengfu (DU-16) acupoint upwards, becoming Brain Wind (Nao Feng); when wind pathogen enters the connections of the head, it becomes Eye Wind (Mu Feng), manifesting as coldness in the eyes; contracting wind after drinking alcohol becomes Leaking Wind (Lou Feng); contracting wind while sweating after sexual intercourse becomes Internal Wind (Nei Feng); contracting wind immediately after washing hair becomes Head Wind (Shou Feng); long-standing wind entering inward becomes Intestinal Wind (Chang Feng) accompanied by undigested stool diarrhea (Sun Xie); wind pathogen remaining at the exterior interstices (Cou Li) becomes Leakage Wind (Xie Feng). Therefore, wind is the chief of a hundred diseases. Regarding its transformations, it may become other diseases, without a fixed pattern, yet the cause of disease always stems from wind Qi.
The Fengfu (DU-16) acupoint of the Du Meridian connects upward to the brain and also communicates with the Taiyang Meridian. The Taiyang Meridian originates from the inner canthus of the eye. Thus, when wind pathogen enters the brain via Fengfu, it causes headache and occipital pain; when it reaches the eye via the Taiyang Meridian, it results in coldness of the eyes. Individuals who drink alcohol often sweat and have loose interstices, allowing wind pathogen to easily enter, hence named Leaking Wind. During sexual intercourse, sweating occurs, and wind pathogen takes advantage of the deficiency to enter internally, hence named Internal Wind. Immediately after washing hair, Yang Qi is dispersed; since the head is the convergence of all Yang meridians, wind pathogen attacks the head. Long-standing wind entering the Fu organs results in Intestinal Wind with undigested stool diarrhea, where food fails to digest and is excreted downward, due to the dispersing and draining nature of wind. All evil pathogens harming humans must do so through wind; thus, wind is the chief of a hundred diseases. Its transformations lead to other diseases without a fixed location, yet the etiology invariably stems from wind Qi.
