This is the most simple answer; it's more natural. Most people turn to herbal medicine or flower remedy therapy because they are looking for a more natural alternative to conventional medications. Organic is the best kind of 'natural'. It ensures that the plants used to create the medicines I dispense are in their most natural form and have been grown without the use of chemicals. The herbal medicines I use in my clinic are often also made from fresh plant material as opposed to dried, which means that the medicines capture the real living essence of the plant.
All of the Bach flower remedies are grown in an organically certified garden based at the Bach Centre in Oxfordshire which is also open to the public.
