100% Organic Milk Thistle tincture is made with Silybum marianum seeds. 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.
