Functions: Supplements and regulates the blood

Indications: Blood vacuity manifesting as dysmenorrhea, irregular menstruation, uterine bleeding, anemia due to various causes, threatened miscarriage, abdominal pain during pregnancy, postpartum weakness, scanty lactation, dry skin, constipation, neurovascular headache, etc.

Signs & symptoms of blood vacuity include:

  • A pale facial complexion

  • Pale lips, nails, and under-eyelids

  • Heart palpitations

  • Night blindness

  • Sinew cramps

  • A pale tingue

  • A fine pulse

Formula explanation: Dang Gui both supplements and quickens the blood. Shu Di supplements the blood and enriches yin. These two are the sovereign ingredients in this formula. Chuan Xiong­ enters the blood aspect or division where it rectifies the qi within the blood. Bai Shao restrains yin and nourishes the blood. Thus all the ingredients in this formula are categorized as blood aspect medicinals.

Dosage: According to Him-che Yeung in Handbook of Chinese Herbs and Formulas, Vol. 2, the standard daily dose in decoction for this formula is 48 grams. Because of the 10:1 concentration ratio and the efficiency of our manufacturing process it would take only 7 capsules per day of Blue Poppy's version of this formula to equal the standard daily dose. The actual prescribed dose should be determined by the practitioner on a case by case basis.
