Dahurian Angelica

Angelica dahurica

Known in traditional Chinese medicine as Bai Zhi, meaning white root, this herb has been counted among the essential materia medica for nearly two thousand years, first recorded in texts like the Shennong Bencao Jing. Practitioners traditionally reached for it to clear frontal headaches, stuffy sinuses, and toothache, and to address the kind of dull, damp heaviness that settles behind the eyes and across the forehead. Just as often, it found its way into face powders and washes, prized for centuries as a beauty root said to brighten the complexion and soften blemishes. It remains one of the most recognizable roots on any traditional apothecary shelf, its pale, fragrant slices instantly familiar to anyone who has browsed a Chinese herb shop.

Safety.

The root contains furanocoumarins that can make skin much more sensitive to sunlight, so avoid sun exposure after topical use, and it may affect blood clotting, so use caution with blood-thinning medication. It has traditionally been avoided during pregnancy. As a carrot-family plant with dangerously toxic look-alikes like poison hemlock and water hemlock, use only root from a properly identified source, never casually foraged.
