Pulse diagnosis, or pulse cutting, is a diagnostic method in which the doctor uses his finger to cut and press the patient’s artery to understand the condition and identify the disease based on the image of the pulse movement. Astringent pulse diagnosis examines the pulse movement is not fluent, weak and thin and late, three or five irregularities, like a light knife scraping bamboo. It is usually caused by blood deficiency, loss of fluid, and stagnation of Qi and blood. It can be seen in anemia, cardiac insufficiency, etc. The astringent pulse is also one of the single-factor and independently significant pulse signs with a difficult pulse shape. It is also the earliest to appear in medical texts and was introduced at the same time as the slippery pulse. The slippery and astringent veins reflect the fluency and difficulty of the pulse (i.e., not fluent) and its degree. For these reasons it makes sense to call both the slippery and astringent veins together since the Nei Jing. Although the astringent pulse is not too uncommon in clinical practice, it is a more difficult pulse to grasp and experience in terms of operating technique. As astringent for the death of blood loss of essence, blood stagnation, also seen in the heavy evidence patients, so it is easier and fine, late, scattered, short, incomplete and other veins to the same time, but not equal to astringent pulse must be with these veins, practice astringent and large, astringent and string long, astringent and heavy number clearly no interruption, and even astringent and number of veins can be seen, the easy to appear in conjunction with the situation as absolutely inappropriate, and then set these people in the standard conditions Obviously it is even more unreasonable, as for the floating is even more inappropriate and can be said to be wrong. Influenced by the “pulse”, the successive pulse books in the discussion of the astringent pulse pulse shape rarely avoid this drawback, all transcriptions quoted “pulse”, quoted part of it, in accordance with this way of thinking gain, alteration of it, in short, are inappropriate and in vain to increase around. For example, the “Thousand Gold Formula” says: “or as a number”. The “Thousand Gold Wing Formula” adds: “Promote the number of light flat is obtained, the heavy hand does not leave its place, or more people and less out??” Cui’s “pulse recipe” says: “weakness and slow astringency.” The ancients according to the “pulse meridian” explained people a breath pulse line three inches, a suction pulse line three inches, breathing fixed rest, the pulse line six inches. A day and night, 13,500 breaths, the pulse line eight hundred and ten feet, this flat human blood gas running the fixed number. The doctor wants to know whether the blood qi is sick or not, not enough to cut the pulse to get it. Or because of melancholy, or because of thick taste, or because of no sweat, or because of the supplement, gas boiling blood, clearing into turbidity, old phlegm and drink, gum and solid mixed, the pulse path blocked, can not be their own, also see astringent state.
