Traditional Pathogenesis

Cause & mechanism

  • This pattern is always seen in one of two circumstances.
  • The first is the mistreatment of cold-induced diseases by sweating, vomiting, or purging; or from blood loss after catching a cold-induced disease.
  • The second is a miscellaneous disease due to yin-blood insufficiency and deficiency of yang qi.
  • Yin-blood insufficiency fails to nourish the heart mind and heart yang deficiency fails to warm the heart vessels, so the patient complains of palpitations.

Clinical presentation

  • Zhi Gan Cao Tang is a well-known formula from《Treatise on Cold Damage》used to treat an intermittent or knotted pulse and palpitations.
  • The insufficient yin-blood fails to fill in the blood vessel and deficient yang qi fails to activate or pump the blood vessel, these two leading to an intermittent or knotted pulse.
  • The treatment should be to enrich heart yin, nourish heart blood, boost heart qi, and warm heart yang in order to restore the pulse and calm palpitations.

Treatment strategy

  • The treatment principle is to tonify Qi-blood and nourish Yin to restore irregular pulse.

Clinical Perspective

Zhi Gan Cao Tang, Sheng Mai San and Tian Wang Bu Xin Dan all support the Heart. Sheng Mai San generates fluids and astringes Qi for Qi-Yin deficiency; Tian Wang Bu Xin Dan nourishes Heart Yin and blood for insomnia with Yin deficiency. Zhi Gan Cao Tang tonifies Qi and blood and restores the pulse for irregular or intermittent pulse with palpitations from Qi-blood and Yin deficiency.

Clinical Differentiation

  • Zhi Gan Cao Tang is a formula that supplements yin, yang, qi, and blood at the same time.
  • This clinical pattern is marked by intermittent or knotted pulse, palpitation, weakness, emaciation, weak breathing, peeled, pale tongue with a scanty coating.

Safety notes: When Zhi Gan Cao Tang is used to treat deficiency-consumption and lung wei disease due to qi-yin deficiency, one should decrease the dosage of, or omit, the warm medicinals such as sheng jiang, gui zhi, and wine since they will cause more yin-fluids deficiency.
