Korean ginseng is more potent than American ginseng but pricier.
Tips
usage
The 丽 here is read lí (second tone), the reading used in the Korean dynasty name 高丽 (Goryeo / Koryo). Don't read it as lì ('beautiful'). The dynasty's name later became the standard Chinese exonym for Korea in many compound nouns.
culture
Korea has cultivated ginseng for over a thousand years; 高丽参 specifically denotes the Korean-grown root, prized in Chinese medicine for tonifying 气. Red ginseng (红参) is the steamed and dried variety, considered the most potent.
