China's traditional Chinese medicine to 

        Patients such as dry, rough, chapped skin, desquamation, dry hair, dry mouth and other clinical symptoms, a dermatologist will use "dry permit" to treatment based on syndrome differentiation. Such as psoriasis, dry itchy skin disease and a series of scales sex skin disease treatment, blood dryness syndrome seems to be one of the most common type of connecting, in the literature, discusses about blood dry permit is not in the minority. But the author thought that this concept is in line with the Chinese medicine theory is questionable. 
 
        The origin and development of dry 
 
        According to the word "dry, dry also", is a kind of relative to the wet pathogenic factors and pathological state, such as FeiJinQing puts it: "dry dry also, to wet it's also". Yi jing "fire was dry, dry and closely linked to fire, hot air, heat consumption jin liquid, dry also damage the body, reason has" the Yang Ming dry ". "Element, q theory of Yin and Yang should be like a big," said: "western dry, dry raw gold, Jin Shengxin, XinSheng lung, lung raw fur", dry sympathies with gold, and gold in the dirt for lung, lung and main fur, therefore, dry most closely relationship with fur. So, excessive dryness evil, main show is the skin dry, desquamation, hair dry, etc. 
 
        Drying with dry and dry inside and outside the drying is one of the six evils, is the breath of the season, the element theory of ask to be really big, "said:" all ills of living also, both born in the wind through the wet dry fire ", "plain question · theory of Yin and Yang should be like a big" is the truth: "dry, dry", all of these instructions drying should be Lord of autumn air. In dry to Yin deficiency, blood deficiency and blood stasis cause more fluid or fluid caused by decreased production or ShuBu poorly. Generally speaking, the acute disease caused by the external dryness, and chronic disease due to endogenous dryness. 
 
        "Blood dryness syndrome" 
 
        About blood dryness syndrome, this paper did not explicitly mentioned in ancient documents. The concept of "dry permit blood" really is put forward in the modern. What is specific time who first proposed, impossible. Some dermatologists Zhao Bingna initiative of TCM was late, but also can not be sure. That I want to ask, why blood dry permit does not appear in the long history of? The problem whether there is is ignored by the ancient people? Have some ideas on this, the author, with fellow. 
 
        The basic theory of bian 
 
        As is known to all, drying with dry and dry, even don't have Yang and Yin dry it. Outside to dry, Wang Mengying in autumn dry typhoid fever "recreate popular treatise on febrile diseases", which section said: "at the beginning of autumn deep cold zephyr, the west country, feeling is sick of dry wind, if this is a cool dry... long sunny no rain, qiuyang exposure, should the sickly temperature drying, the hot and dry." It said the six evils of the dry, such deals, too numerous to count. 
 
        But for dry, inside the expound directly is not much, endogenous dryness of the disease, mostly cloudy. "On, ask to be really big" said: "to dry her inside, with bitter temperature, with XinGan", Ephraim measurement certificate, when dry hurt inside, clinical manifestations of Yin syndrome, dry outside rather than we take for granted the similar drying of card less. 
 
        Clinical discrimination 
 
        According to the current scholars explained the clinical manifestations of blood dry, we can see that mainly contains the blood deficiency, blood stasis, jin kui, Yin deficiency, wind filled part of the performance. In other words, blood dryness syndrome is more than some of the disease and simple set of incomplete performance. 
 
        Skin is dry, rough, chapped, desquamation, hair dry, dry mouth, dry nose, defecate dry, dry throat, such as a class of clinical symptoms, apparently caused by dry outside. But by reading ancient Chinese medical will find, past dynasties doctor thought that this is due to dry evil, also is the outcome of dry consumed outside the body.
