Tight Pulse (紧脉)

Appearance (体象歌)

紧脉有力，左右弹指；如绞转索，如切紧绳。

Clinical Indications (主病歌)

紧主寒邪，又主诸痛。左寸逢紧，心满急痛；右寸逢紧，伤寒喘嗽。左关人迎，浮紧伤寒；右关气口，沉紧伤食。左尺见之，脐下痛极；右尺见之，奔豚疝疾。

Clinical Significance

The Tight Pulse indicates cold patterns and pain. It forms when cold pathogenic factors attack the body, yang qi is constrained, the channels become tense, and qi-blood circulation is obstructed. The pulse feels tight and forceful, like a twisted rope or taut cord. It represents cold congelation and the struggle between pathogen and healthy qi, commonly seen in external wind-cold invasion, interior cold congelation, and various painful disorders. At the left inch position, tight pulse indicates cold congealing the heart vessels with chest fullness and acute pain. At the right inch, it reflects wind-cold binding the lungs with aversion to cold, fever, headache, cough, and asthma. At the left guan, it indicates cold in the exterior or cold in the liver channel. At the right guan, it reflects cold-food injury to the middle burner with cold abdominal pain, vomiting, and diarrhea. At the left chi, it points to lower burner cold congelation with severe pain below the navel and cold lower back and knees. At the right chi, it indicates cold hernia or running piglet qi. Floating and tight indicates exterior cold; deep and tight indicates interior cold; tight and wiry indicates cold in the liver channel or food retention. Combined pulse diagnosis is essential for correct pattern differentiation.

Treatment and Care

For cold congelation with a Tight Pulse, treatment warms the channels, scatters cold, and relieves pain. External wind-cold excess is treated with pungent-warm exterior-releasing formulas such as Ma Huang Tang or Gui Zhi Tang. Cold congealing the heart vessels with chest pain is treated by warming yang, scattering cold, and activating blood with Zhi Shi Xie Bai Gui Zhi Tang or Guan Xin Su He Wan. Middle burner cold with cold abdominal pain is treated with Li Zhong Tang, Fu Zi Li Zhong Wan, or Wu Zhu Yu Tang. Cold in the liver channel with hernial pain is treated with Nuan Gan Jian or Tian Tai Wu Yao San. Lower burner cold congelation with severe pain is treated with Da Huang Fu Zi Tang or Wen Jing Tang. Daily care requires strict avoidance of cold and keeping the chest, back, abdomen, and legs warm. Eat warming foods such as ginger, scallion, lamb, and Sichuan pepper; avoid raw fruits and cold drinks. During pain attacks, apply hot compresses or moxibustion to the painful area such as Shen Que, Guan Yuan, Zu San Li, and San Yin Jiao to scatter cold and unblock the channels. After acute cold pain resolves, continued warming therapy for one to two weeks helps prevent recurrence, and protecting the nape and lower back from drafts is especially important in wind-cold sensitive individuals.
