Golden corydalis (Corydalis aurea) is a small plant of North America's undergrowth and rocky ground, recognizable by its clusters of bright yellow flowers. Certain Native American nations credited it with pain-easing properties, in a cautious, limited use, as the plant belongs to a family known for its potent alkaloids.
The root of golden corydalis was traditionally used externally or as a light preparation to relieve certain pain, particularly muscle or joint pain, according to reported Native American uses.
Certain traditions report the use of poultices made from crushed root on bruises and skin swelling.
The whole plant, given its alkaloid-rich botanical family, was reportedly used occasionally for its mild sedative properties in certain traditional uses.
A plant containing alkaloids whose effects and toxicity are insufficiently documented: internal use to be avoided without the advice of a qualified professional. Discouraged for pregnant or breastfeeding women, as well as children. Do not combine with sedatives, anti-anxiety medication, or other substances acting on the central nervous system, because of the risk of interaction. Any prolonged or high-dose use should be avoided; consult a health professional before any use.
