Choppy Pulse (涩脉)

Appearance (体象歌)

涩脉蹇滞，如刀刮竹；迟细而短，三象惧足。

Clinical Indications (主病歌)

涩为血少，亦主精伤。寸涩心痛，或为怔忡。关涩阴虚，因而中热；右关土虚，左关胁胀。尺涩遗淋，血利可决；孕为胎病，无孕血竭。

Combined Patterns (兼脉歌)

涩而坚大，为有实热；涩而虚软，虚火炎灼。

Clinical Significance

The Choppy Pulse indicates blood deficiency, essence injury, qi stagnation, and blood stasis. It forms when yin blood is depleted and the vessels lose nourishment, or when qi stagnation and blood stasis obstruct the vessels, causing the pulse to feel rough and hesitant, like scraping bamboo with a dull knife. A deficient choppy pulse usually results from chronic illness, blood loss after childbirth, or severe yin-blood depletion. An excess choppy pulse usually arises from emotional constraint, cold congelation, or static blood obstructing the channels. At the inch position, choppy pulse indicates blood deficiency or blood stasis in the heart and lungs, with heart pain, palpitations, and chest tightness. At the guan position, it points to yin-blood deficiency of the liver and spleen or qi stagnation and blood stasis, with rib-side distension and pain, dry mouth, and poor appetite. At the chi position, it reflects essence-blood deficiency or stasis in the lower burner, presenting as seminal emission, urinary dribbling, uterine bleeding, bloody stools, or infertility. In pregnant women, a choppy pulse may indicate fetal disease or threatened miscarriage; in non-pregnant women with chi choppy pulse, it may indicate severe blood exhaustion requiring careful evaluation. Long-standing blood stasis may require persistent therapy with moving and transforming medicinals over several weeks, and emotional stress and cold exposure are common aggravating factors that should be minimized during treatment.

Treatment and Care

For blood and essence deficiency with a Choppy Pulse, treatment nourishes blood and enriches yin. Heart blood deficiency with palpitations is treated with Gui Pi Tang or Tian Wang Bu Xin Dan combined with Si Wu Tang. Liver-kidney yin deficiency is treated with Liu Wei Di Huang Wan, Zuo Gui Wan, or Da Bu Yin Wan. For choppy pulse with force due to blood stasis, activate blood and resolve stasis with Xue Fu Zhu Yu Tang, Tao Hong Si Wu Tang, or Sheng Hua Tang. For qi stagnation and blood stasis with chest and rib pain, move qi and activate blood with Chai Hu Shu Gan San combined with Shi Xiao San. Daily care includes eating blood-nourishing foods such as red dates, longan, black sesame, goji berries, mulberries, and angelica sinensis; avoiding spicy, drying, and blood-moving substances. Maintaining emotional balance and adequate sleep protects yin and blood. For blood stasis, moxibustion at Ge Shu, Xue Hai, and San Yin Jiao can assist blood circulation, but should be avoided when there is active bleeding or bleeding tendency. Warm compresses over the lower abdomen and regular moderate exercise promote circulation in blood stasis patterns, while adequate iron-rich foods support recovery, but heavy blood-moving substances should be used cautiously.
