Dosages (Dong Quai) — 4.5–12 g (FAY); 3–15 g root (APA); 3–4 g root/day (SKY); 1–3 tsp
root/day; 1–3 tbsp fresh root (PED); 2–4 g dry root (PED); 3–15 g dry root/day (MAB); 2–6 g dry
root/day or 4–12 ml fluid extract (1:2) (for all his Chinese posologies, these ratios apply) (KEB);
3 g dry root:15 ml alcohol/15 ml water (PED); 4–8 ml flower extract (1:2) (MAB); 3 (530 mg)
capsules 3 ×/day (NH).
Contraindications, Indications, and Side Effects (Dong Quai) — Class 2b (AHP). Psoralens
can be phototoxic and carcinogenic. The aqueous extract inhibits experimentally induced IgE
titers, suggesting immunosuppressive potential. “Its use cannot be recommended” (LRNP, April
1990). Pregnant and nursing women, or patients with diarrhea, should not take except under a
doctor’s instruction. AHP notes that it is Americans and Canadians, not Chinese, who warn
against use in pregnancy. Contraindicated in those with bleeding tendencies or heavy menstrual
periods, during first trimester of pregnancy, for abortion-prone women, and in acute viral infec-
tions (KEB). “Canadian regulations do not allow dong-quai as a non-medicinal ingredient for
oral use products” (Michols, 1995).
Extracts (Dong Quai) — Decoction uterocontractant in dogs. Decoction and tinctures hypotensive
in anesthetized animals (PED). Ligustilide at 450 mg/day helped 77% of dysmenorrheics as opposed
to 38% for aqueous extracts of the herb (KEB). Butylidenephthalide, butylphthalide, and ligustilide
antispasmodic (FAY). Treatment of infertile women by uterine lavage of the extract for up to 9
months restored tubal patency in 79%; 53% became pregnant. Almost nontoxic LD50 = 100,000
mg/kg (MAB).
