Water, Organic Alcohol & organic fresh ginkgo extract.100% Organic Ginkgo tincture is made with fresh Ginkgo biloba leaves. Our leaves come from the ancient Ginkgo biloba tree at Kinnersley Castle in Herefordshire. 100% organic and natural, no synthetics whatsoever. The tincture extraction technique involves pure organic alcohol which draws elements from within the plant into the solution. To remove/lessen the alcohol content, simply add the required amount to an egg cup of freshly boiled water and leave to cool; the majority of the alcohol will evaporate with the steam. Created in the United Kingdom using traditional craft skills and plant knowledge. Certified organic by the Soil Association.
