Traditional Use

Primary Actions

  • Invigorates Blood and dispels stasis ... Hong Hua is one of the classic flowers for dark clots, fixed pain, and menstrual obstruction.
  • Unblocks menstruation and alleviates pain ... dysmenorrhea, amenorrhea, and postpartum abdominal pain are central traditional uses.
  • Reduces swelling and relieves traumatic injury ... bruising, contusion, and persistent stasis pain are common non-gynecologic indications.
  • Moves the channels without the heavy harshness of stronger blood-breaking substances ... this makes it versatile but still safety-relevant.

Secondary Actions

  • This page must stay clearly separate from `saffron` / Xi Hong Hua ... both move Blood, but they are not interchangeable in identity, potency, price, or traditional handling.
  • The medicinal part is the dried safflower floret cluster, not the oilseed or a decorative garden flower.

Classic Formulas

  • Tao Hong Si Wu Tang ... classic blood-stasis and menstrual formula using Hong Hua with Tao Ren.
  • Xue Fu Zhu Yu Tang ... famous chest-stasis formula where Hong Hua helps move constrained Blood.
  • Shen Tong Zhu Yu Tang and trauma-oriented formulas ... used when channel stasis causes persistent pain.

Classical References
