Known in TCM as Ting Hu Suo (延胡索), this acrid and bitter, warm herb enters the Heart, Liver, and Spleen. Traditionally, it invigorates Blood, moves qi, and relieves pain ... Ting Hu Suo stays within the classic Yan Hu Suo pain-herb lane, especially when fixed pain and distention show both qi stagnation and blood stasis, most often applied for abdominal pain, dysmenorrhea, and chest pain. Modern research has identified Tetrahydropalmatine among its active constituents.

Traditional Use

Primary Actions

  • Invigorates Blood, moves qi, and relieves pain ... Ting Hu Suo stays within the classic Yan Hu Suo pain-herb lane, especially when fixed pain and distention show both qi stagnation and blood stasis.
  • Relieves chest, flank, epigastric, and abdominal pain ... it is widely used for digestive, menstrual, and constrained Liver-type pain patterns rather than for vague deficiency aches.
  • Addresses traumatic and gynecologic pain ... trade-name variation does not change the core materia medica identity, so the herb still belongs in dysmenorrhea, postpartum stasis, and injury-related pain formulas.

Secondary Actions

  • This page preserves the Ting Hu Suo naming lane as a raw trade-lot sibling of the canonical `corydalis-tuber` record rather than pretending it is a different species or a different medicinal function.
  • The associated illustration notes emphasize a larger clustered raw tuber lot, which is useful for merchandising accuracy but does not justify separate pharmacology.

Classic Formulas

  • Jin Ling Zi San ... classic pairing with Chuan Lian Zi for hypochondriac, epigastric, and lower-abdominal pain from constrained Liver qi with heat or stasis.
  • Yan Hu Suo Zhi Tong Wan ... pain-formula tradition built directly around corydalis for generalized stagnation pain.
  • Shao Fu Zhu Yu Tang and related gynecologic stasis formulas ... contexts where corydalis helps move and relieve lower-abdominal pain.

Classical References

  • Traditional materia medica consistently treats Yan Hu Suo and its close naming variants as premier analgesic herbs that move both qi and blood.
  • Editorially, the key point is that Ting Hu Suo belongs to the same Corydalis yanhusuo root-tuber stream as Yan Hu Suo, Xuan Hu, and Yuan Hu trade labels.

Modern Research

Active Compounds

  • Tetrahydropalmatine ... the best-known alkaloid associated with analgesic and sedative effects
  • Dehydrocorybulbine ... a pain-related alkaloid studied in neuropathic and inflammatory models
  • Protopine and related isoquinoline alkaloids ... supportive constituents within the broader corydalis alkaloid profile
  • Quaternary and tertiary alkaloid fractions ... the main pharmacologically active chemical families in raw corydalis tuber material

Studied Effects

  • A 2021 review summarized the analgesic chemistry of Corydalis yanhusuo and highlighted its rich alkaloid profile as the basis for the herb's long-standing reputation as a pain medicine (PMID 34946576).
  • Experimental work showed that Corydalis yanhusuo extract has significant antinociceptive activity across inflammatory and neuropathic pain models, supporting its broad traditional use for painful stagnation (PMID 27622550).
  • A 2022 review of processing, compatibility, pharmacology, pharmacokinetics, and safety underscored that vinegar-processing changes efficacy and toxicity considerations and remains central to modern understanding of raw and prepared corydalis lanes alike (PMID 35003289).

Safety & Interactions

Contraindications

  • Pregnancy
  • Heavy menstrual bleeding without stasis
  • Severe qi or blood deficiency pain without obstruction

Cautions

  • Ting Hu Suo is still a moving pain herb and can be too dispersing when there is active bleeding or clear deficiency without stasis.
  • Its alkaloids may cause dizziness, sedation, or gastrointestinal upset in sensitive patients or excessive doses.
  • Trade-lot naming does not change the need for caution around prolonged unsupervised use.
