Ting Hu Suo Corydalis Root Classic Formulas … Natural Herb Library

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.

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.

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.
