Traditionally, corydalis has been used for relief of menstrual cramps, relief of abdominal pain and cramps, and invigoration of the blood. Corydalis exhibits a strong analgesic effect (but is a hundred times less potent than morphine). It has a slower onset of action than morphine. Evidence of dependence has not been noted with corydalis. The herb has pronounced sedative qualities and improves sleep. It also has marked anti-inflammatory properties and improves coronary blood flow.

Suggested Dosage: Highly dependent on the type of preparation used.

Side effects: Generally well tolerated. Avoid in pregnancy and while breastfeeding. Overdose can cause respiratory depression, sedation, and tremor. The potential for habituation dependence with Corydalis is much less than narcotics, but a small risk is still present. Should be avoided with active liver disease.
