Are ginkgo seeds a food alternative to the extract?
Seeds and leaf extracts are not interchangeable. Fresh seeds are toxic when eaten, and serious adverse effects have also been reported after roasted seeds or crude plant material. The safety experience with studied leaf extracts does not make those alternatives safe. 1
