Corydalis Tuber Pieces

Corydalis Tuber Pieces (Corydalis yanhusuo) are the dried tuber slices of a traditional medicinal plant used in Traditional Chinese Medicine (TCM) under the name Yán Hú Suǒ (延胡索). This herb is highly regarded for its ability to invigorate blood, move qi, and relieve pain, making it one of the most important botanical analgesics in classical Chinese practice. Its nature is considered acrid, bitter, and warm, allowing it to penetrate stagnation and restore smooth circulation.

In TCM, Yan Hu Suo enters the Heart, Liver, and Spleen channels, where it helps disperse blood stasis, regulate qi, and alleviate pain in virtually any part of the body. It is traditionally used for menstrual cramps, abdominal pain, chest pain, flank pain, traumatic injury, headaches, and digestive discomfort, particularly when symptoms are associated with stagnation and obstruction. Its dual action of moving both qi and blood makes it especially effective when pain involves mixed patterns.

Corydalis is frequently included in formulas for dysmenorrhea, post-injury pain, and stress-related tension, where stagnation has led to discomfort. Unlike harsh narcotic substances, it is traditionally valued for addressing the root cause of pain through improved circulation, rather than simply dulling sensation.

Modern research shows that Corydalis yanhusuo contains tetrahydropalmatine (THP), alkaloids, and bioactive compounds with documented analgesic, sedative, antispasmodic, and circulation-enhancing effects. These constituents support its long-standing reputation as a natural pain-relieving and blood-moving herb.

Each batch of Corydalis Tuber Pieces (Corydalis yanhusuo) is carefully harvested and sliced to preserve their firm tuber structure and concentrated medicinal compounds. When decocted, they produce a bitter, slightly warming preparation traditionally used to invigorate blood, move qi, relieve pain, and restore smooth internal circulation.
