Xinxiu bencao

The Xinxiu bencao (Chinese: 新修本草; pinyin: Xīnxiū běncǎo), also known as the Tang bencao (Chinese: 唐本草; pinyin: Táng běncǎo), is a Chinese pharmacopoeia written in the Tang dynasty by a team of officials and physicians headed by editor-in-chief Su Jing. It borrowed heavily from—and expanded upon—the earlier Bencao jing jizhu by Tao Hongjing. The text was first published in 659; although it is now considered lost in China, at least one copy exists in Japan, where the text had been transmitted to in 721.
