Red Peony Root

Herb actions

Invigorating the Blood and dispelling Blood stasis are Chi Shao's core action, easing the pain of a painful or absent menstrual cycle, fixed abdominal masses, and veins swollen from Blood that has stagnated. Chi Shao also addresses stagnation after a traumatic injury, reducing the bruising, pain, and swelling that follow impact. When Heat moves into the Blood level, expressing as a fever, a purple tongue, or spotting and bleeding under the skin, it cools and calms the Blood. Liver fire also surfaces as redness, swelling, and pain in the eyes, and the same bitter, heat-draining action helps to reduce the swelling of sores and abscesses while they remain in an early, active stage.

Flavor and nature

Chi Shao's bitter flavor drains heat from the Blood and sour carries the herb into the Liver channel, since the sour flavor typically directs a substance toward the Liver. Gathered from the wild root rather than cultivated like Bai Shao (white peony root), Chi Shao carries a stronger bitter-cooling character, which helps it move and cool the Blood while Bai Shao's flavor nourishes and consolidates.

Chi Shao's bitter, cooling action also clears the fire behind red, swollen, painful eyes, and the heat behind sores and boils in their early, active stage. Fixed abdominal masses, bruising from injury, and a painful or irregular menstrual cycle all trace back to Blood that has stopped moving, and the same draining, descending action pushes that stagnant Blood forward again. This action suits Heat that is excess, not the deeper Heat of Yin deficiency.

How Daodi uses it

Patterns that address stagnant Blood and Heat call for Chi Shao. We typically add it to formulas addressing a painful or irregular menstrual cycle rooted in Blood stasis, supporting the Liver's role in storing and releasing Blood smoothly. Because Chi Shao clears excess Heat, we turn to herbs like Mu Dan Pi or Sheng Di Huang when the pattern involves Yin deficiency.

Herb pairings

• Bai Shao-Chi Shao cools the Blood and dispels stasis while Bai Shao nourishes the Blood and softens the Liver, addressing spasms and pain that stem from combined Blood deficiency and stagnation.

• Dang Gui-The two combine for Blood stasis patterns behind fixed abdominal masses and an absent menstrual cycle, moving stagnant Blood while easing the pain that accompanies it.

• Chuan Xiong-Both herbs move stagnant Blood, supporting formulas for gynecological pain and the bruising, pain, and swelling that follow trauma.

• Xiang Fu-Xiang Fu moves Qi while Chi Shao moves Blood, together addressing flank and abdominal pain along with a painful menstrual cycle from combined Qi and Blood stagnation.

• Mu Dan Pi-Both herbs cool the Blood and dispel stasis, with the combination directed at Heat that has entered the Blood level.
