It contains analgesic, antispasmodic, sedative, emmenagogue, deobstruent, anti-arrhythmic, bitter, blood stimulant, cardio-protector, hypnotic, alterative, analgesic, antiperiodic; astringent, contraceptive, diuretic, sedative and tonic properties.


Corydalis is a member of the poppy family, and like many Papaverceae Corydalis are an anodyne, a central nervous system depressant, cardiotonic, and sedative.


The dried rhizome of Corydalis is usually recommended at 5 – 10 grams per day in capsules. Can be taken as a tea, but it is bitter. Used with white peony, cramp bark and valerian for menstrual cramping, pain relief and insomnia.


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.


People with insomnia were able to fall sleep more easily after taking 100 to 200 mg per day of a corydalis extract (called dl-tetrahydropalmatine, or DHP), according to a preliminary report.


The root of the herb has been conventionally recommended to relieve pains as well as reinforce the circulation system for hundreds of years.
