Ting Hu Corydalis Root Classic Formulas … Natural Herb Library

Primary Actions

Invigorates Blood, moves qi, and relieves pain ... Ting Hu is still the same Corydalis yanhusuo medicinal stream used when qi stagnation and blood stasis combine into distending or fixed pain.
Relieves chest, flank, and abdominal pain ... it is suited to constrained, obstructive pain patterns rather than to generalized weakness or depletion aches.
Supports menstrual and trauma formulas ... Ting Hu retains the same traditional role in dysmenorrhea, postpartum pain, and traumatic injury as other raw yanhusuo naming lanes.

Jin Ling Zi San ... classic constrained-pain pairing that uses corydalis to move stagnation and reduce pain.
Yan Hu Suo Zhi Tong Wan ... patent-style pain-formula logic centered on corydalis.
Shao Fu Zhu Yu Tang modifications ... gynecologic stasis settings in which corydalis helps relieve lower-abdominal pain.

Materia medica tradition values corydalis for treating both qi and blood aspects of pain, which is why it spans digestive, gynecologic, traumatic, and channel-obstruction use.
Ting Hu should therefore be read as an alias-track raw lot within the broader Yan Hu Suo family, not as a separate herb.
