Cautions

contraindication Bleeding that will not stop
pregnancy Not to be used in pregnancy; the aerial part of the same plant is a recognised uterine stimulant
contraindication Liver stagnation arising from deficient Liver Blood
contraindication Blood or Yin deficiency, which a moving, draining herb aggravates
contraindication Yang deficiency with prolapse, where a downward-moving herb works against treatment
caution Toxic reactions have been reported above a specific quantity; keep within the dose range, under supervision
caution Heavy or irregular bleeding, amenorrhea and postpartum pain need medical diagnosis, and a sudden painful red eye should be seen the same day

Interactions

Drug interactions

Warfarin, direct oral anticoagulants and antiplatelet drugs, and around surgery: Blood-invigorating herbs as a class call for care (theoretical; no interaction reported for this herb)
Uterotonic medicines, and care around pregnancy or labour: decisions belong with the treating clinicians, given the plant's uterine action (theoretical)
