Chinese herbal medicines used in pregnancy: a population-based survey in Taiwan

Pharmacoepidemiol Drug Saf. 2007 Apr;16(4):464-8. doi: 10.1002/pds.1332.


Purpose: To explore the use (prevalence and related factors) of Chinese herbal medicines used by pregnant women.

Methods: We used multistage stratified systematic sampling to recruit 2048 postpartum women from the Taiwan national birth register between November and December 2003. Subjects underwent a home interview 6 months after their deliveries. A structured questionnaire was successfully applied to 87% of the sampled population.

Results: At least one Chinese herbal medicine was used during pregnancy by 24.1% of the interviewed subjects. Pregnant women with threatened abortion appeared to use more Chinese herbal medicines than other pregnant women.

Conclusion: Chinese herbal medicines are frequently used by pregnant women in Taiwan and are very frequently used by those with a threatened abortion.
