Viola philippica
Also known as purple-flowered violet, Yedo violet, Tokyo violet, zi hua di ding, zǐ huā dì dīng, dì dīng cǎo, jiàn tóu cǎo.
Zi hua di ding is a small stemless violet with purple flowers that grows in lawns, field edges and open ground across China, Korea and Japan. The whole plant is gathered in spring and used fresh or dried. It is one of the standard heat-clearing, toxin-resolving herbs of the Chinese materia medica, most familiar as a member of the classical formula for boils and carbuncles alongside honeysuckle flower, dandelion and wild chrysanthemum. The pharmacopoeia lists it under the name Viola yedoensis, which botanists now treat as the same species as Viola philippica.
