Shishiudo(scientific name: Angelica pubescens) is a large perennial herbaceous plant in the family Apiaceae, native to Japan. It is native to the mountains of Honshu, Shikoku, and Kyushu. Its thick stems are hollow and branched. The base of the petiole expands into a navicular shape to enclose the young stem. It produces many small white flowers in late summer to late autumn with scattered inflorescences.
