Dahurian angelica · Bai Zhi
Angelica dahurica (Fisch. ex Hoffm.) Benth. & Hook. f. ex Franch. & Sav. · Root
Name and part used
An Apiaceae herb with divided leaves, large white umbels, and a fleshy root.
Traditional context
HKBU records Bai Zhi as Angelica dahurica root, with regional cultivars. Apiaceae includes poisonous look-alikes, so an image cannot identify a wild plant.
Modern evidence
Furocoumarins in this species make controlled identity and handling important; traditional descriptions are not proof of treatment for headache or sinus disease.
Safety
Do not collect Apiaceae plants yourself. People taking medicines, sensitive to sunlight, pregnant, or with chronic conditions should ask a professional before considering products.
Pairing in reference texts
It appears in some classical formula records; textual co-use does not prove a commercial product is interaction-free.
