The most effective and simplest way of taking ginkgo is as a tincture. To make a tincture, place 150g of dried ginkgo leaves or 400g of fresh ginkgo leaves in a jar and cover with 500ml of vodka. Cover and store in a dark place for 4 weeks, shaking the jar daily. After 4 weeks, strain the mixture, pressing all liquid from the ginkgo. Stored in a glass bottle, this will keep for up to a year. For those who wish to avoid consuming alcohol, ginkgo tea is very simple to make. Simply add 1 cup of boiling water to 1 teaspoon of dried ginkgo or 1 tablespoon of fresh ginkgo. Allow to stand for several minutes, then sweeten as desired. The disadvantage to taking ginkgo in tea form is that the required dosage is much higher – 2-3 cups per day, rather than the 1-3 teaspoons of tincture.
