Dosing
The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
Adults (18 years and older)
Dong quai is used in numerous herbal combinations, and various doses have been used both traditionally and in research in China. Because of this variation and lack of high-quality studies, no specific recommendations can be made. Safety and effectiveness are not established for most herbal combinations, and the amounts of Dong quai present from batch to batch may vary.
Powdered or dried root/root slices, fluid extracts, tinctures, decoctions, and dried leaf preparations of Dong quai are available to be taken orally. Topical preparations are available to be applied to the skin. Safety of intravenous use is not established, although it has been reported in research.
Children (younger than 18 years)
There is not enough scientific data to recommend Dong quai for use in children, and it is not recommended due to potential side effects.
