Effective Medicines (Yoku kiku yakushū)

Effective Medicines (Yoku kiku yakushū, 能効藥種) is a mid-nineteenth-century woodblock-printed book whose illustrations were designed by Mori Kansai under the alternative art name Ichirentei Kansai, circa 1847-1852. The volume belongs to the category of practical illustrated handbooks (jitsuyō ehon) that flourished in late Edo Japan: combining a textual treatise on materia medica and herbal remedies with woodblock illustrations of plants, animals, and human subjects. Kansai's illustrations bring the Mori-Kishi school's natural-history discipline to bear on the medical-botanical subject matter, drawing herbs, insects, animals, and figures with the same close observation that he applied to his painting practice. The Museum of Fine Arts, Boston copy (object 461846), made accessible through the museum's collections database and the ukiyo-e.org aggregator, demonstrates Kansai's role in the Osaka and Kyoto woodblock book trade — a side of his career less commonly noted than his painting but significant for placing him in the broader print tradition.
