US researchers evaluated recommendations made by health-food store employees in Phoenix metropolitan, USA, regarding treatment of nausea/vomiting and migraines during pregnancy. Telephone calls were made by a disguised shopper to 155 health-food stores. The caller posed as a woman 8 weeks’ pregnant asking for recommendations for treatment of nausea/vomiting and migraines. Responses and recommendations were recorded and then compared with current scientific evidence. Eighty-nine percent of stores offered recommendations for nausea/vomiting and 82% provided recommendations for migraines. The use of ginger was the most recommended therapy for nausea/vomiting. Only 3.6% of respondents recommended correct usage, but failed to supply the correct dosage and duration. A total of 15 (5%) of 278 recommendations, for both nausea/vomiting and migraines, were for products contraindicated in pregnancy.
