Ginkgo and MemoryGinkgo and Memory

JAMA. 2003;289(5):546. doi:10.1001/jama.289.5.546-a

To the Editor: Dr Solomon and colleagues1 found that an over-the-counter ginkgo supplement did not enhance memory in elderly individuals after 6 weeks of supplementation at the manufacturer's recommended dose and duration. The authors acknowledged that they did not conduct an independent laboratory analysis of the product. Unfortunately, quantitative analysis of the product is proprietary company information (Anne LaRusso, product manager, and David R. Morrison, director of scientific affairs, Boehringer Ingelheim; written communication, 2002). As a result, the exact quantity of the active ingredients remains unknown.
