[Investigation of genus Ardisia in Bencao literature]

Based on a systematic review of morphology and distribution of plants, alternate names, actions, and properties of herbs recorded in ancient and modern literatures, in combination of field investigation, 18 Chinese herbal medicines recorded in ancient bencao literature were regarded to be derived from 7 species in the Ardisia genus. Among them, the variety Ardisia crenata f. hortensis was identified as the source of Zhushagen and Zijinniu. A. hanceana is referenced as Tiesan in the illustrated atlas of Botanical Nomenclature (Zhiwu Mingshi Tukao). The name Pingdimu refers to a different substance in the illustrated atlas of Botanical Nomenclature and the Flower Mirror (Huajing). The medicinals named Yedihong, Aicha, and Duanjiao sanlangare all derived from A. japonica. The origin of the herb Xiaoqing referenced in the Illustrated Classic of the Materia Medica (Bencao Tujing) is A. pusilla. The medicinals Bailiangjin, Jiuguanxue and Zoumatai are derived from A. crispa, A. brevicaulis, and A. gigantifolia, respectively. This investigation clarifies the botanical sources and actions of related Chinese medicinal materials in the genus Ardisia, and provides clues and evidence for utilizing and developing their medicinal plant resources.
