Herbal medicine has been practised for centuries, and until about 50 years ago, nearly all of the entries in pharmacopoeias describing the manufacture of drugs indicated a herbal origin. For example Asprin was discovered in the last century from the herb willow bark, by isolating one of its active constituents salicin. Today it is recognised by the World Health organisation that herbs are the most widespread form of medicine used by people living on our planet. Naturopathically, they can be taken in a variety of forms and, correctly administered, have a profoundly positive effect on an individual’s health.
