Overview

Gromwell's Korean name, jichi, is still recognized today mainly through its use as a purple dye and as the base of a traditional skin ointment (jacho-gobyak). The Donguibogam records exactly this dual identity — noting it is the same root used to dye things purple, alongside its medicinal use for jaundice-type swelling and children's pox rash.
