Various types of corydalis have been included in traditional Chinese medicine (TCM) preparations and are most commonly used for the treatment of gastritis-like disorders. Corydalis has been studied for other medical conditions, including pain caused by intense cold, parasitic infections, irregular heart rhythms, chest pain, and bacterial infections (especially from Helicobacter pylori). There is currently not enough human evidence to support these or any uses of corydalis.
Corydalis may interact with certain medications, including sedatives, hypnotics, drugs taken for irregular heart rhythms, some pain relievers, and anti-cancer drugs and may be unsafe for use during pregnancy.
EvidenceDISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Angina (chest pain):
Corydalis may be of benefit in chest pain caused by clogged arteries called angina. More studies are needed to determine if corydalis is effective for this use.
H. pylori infection in stomach ulcers:
Early studies suggest that corydalis may be of benefit in bacterial infections with H. pylori in stomach ulcers. However, more evidence is needed before a recommendation may be made.
Early study suggests that corydalis may have pain-relieving properties. High-quality clinical research is needed to confirm these findings.
Corydalis may be helpful in the treatment of infections caused by the parasite Echinococcus granulosus caused by the Hydatid worm. More studies are needed in this area.
TraditionWARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.
Antibacterial, cancer, gastritis, HIV, hypnotic, pain relief, sedation, ulcers.
Adults (18 years and older)
Doses of 3.25 grams and 6.5 grams of raw corydalis extracts have been taken by mouth for the treatment of pain. Rotundium, a component of corydalis, has been used for abnormal heart rhythms.
Children (under 18 years old)
There is no proven safe or effective dose for corydalis in children.
SafetyDISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Avoid in individuals with known allergy or sensitivity to corydalis.
