Traditional Use

Primary Actions

  • Warms the channels and stops bleeding - Ai Ye is a classic uterine and blood-channel herb for cold-pattern bleeding, prolonged spotting, and excessive menstrual loss.
  • Dispels cold and alleviates pain - it is used for dysmenorrhea, abdominal pain from cold in the womb, and cold-damp pain when warmth is needed.
  • Calms the fetus - traditional use includes threatened miscarriage when uterine bleeding or restlessness arise from cold and deficiency rather than heat.

Secondary Actions

  • Ai Ye is both a decoction herb and the foundational material for moxa, so its internal and external traditions are unusually well developed.
  • It must be kept distinct from other Artemisia drugs such as Qing Hao and Yin Chen Hao, which are much cooler and serve very different clinical roles.

Classic Formulas

  • Jiao Ai Tang - classic formula for uterine bleeding, abdominal pain, and fetal-restlessness patterns in which Ai Ye anchors the warming and hemostatic strategy.
  • Ai Fu Nuan Gong Wan and related womb-warming formulas - traditional use for cold infertility, menstrual pain, and lower-abdomen cold.
  • Ai Ye charcoal or moxa preparations - classical part-processing pathways used to emphasize hemostatic or warming-external applications.

Classical References

  • Traditional references describe Ai Ye as acrid, bitter, and warm, entering the Liver, Spleen, and Kidney to warm the channels, stop bleeding, dispel cold, and calm the fetus.
  • The herb's dual life as internal medicine and moxibustion material explains why it remains one of the most culturally persistent warming gynecologic herbs.
  • Dao-di Qichun mugwort is especially prized in moxa traditions, but the monograph here stays focused on the medicinal leaf rather than on branded moxa products.

Modern Research

Active Compounds

  • Volatile oils such as cineole, borneol, camphor, and related terpenes - key aromatic constituents of Ai Ye
  • Flavonoids and phenolic acids - anti-inflammatory and antioxidant fractions
  • Sesquiterpenes and polysaccharides - broader immunomodulatory and bioactive components investigated in the species

Studied Effects

  • A 2021 review summarized Artemisia argyi research across anti-inflammatory, hemostatic, antimicrobial, antioxidant, and uterine-related domains, reflecting why Ai Ye remains one of the better studied warming gynecologic herbs (PMID 34847785).
  • A 2023 study found that an Artemisia argyi leaf extract reduced inflammatory injury in acute pancreatitis by suppressing caspase-11-mediated pyroptosis, providing a modern mechanistic example of its anti-inflammatory potential outside simple folklore (PMID 36754190).
  • A 2016 paper reported anti-inflammatory and anti-blood-stasis effects from Artemisia argyi essential oil in experimental models, supporting the relevance of the leaf's volatile fraction to both pain and circulation-focused traditional use (PMID 26894818).

Safety & Interactions

Contraindications

  • Heat-pattern bleeding or yin deficiency heat with reckless bleeding
  • Strong uterine heat signs rather than cold-deficiency pregnancy restlessness

Cautions

  • Ai Ye is traditionally used in pregnancy only in specific cold-deficiency bleeding or restless-fetus patterns, not as a general unsupervised pregnancy herb.
  • Concentrated essential oil products are not equivalent to ordinary decoction doses or moxa use and may be more irritating.
  • Because the herb has real warming and uterine activity, pattern differentiation matters more than with generic mugwort teas.
