Do you know that many, maybe 75%, of all typical medications are refinements of herbal medicines? One instance of this is the isolation of morphine from opium in 1806. This was the primary time that chemical methods were used to extract the energetic chemical constituents of an herb. The chemical processes used to isolate morphine led to the production of codeine, the broadly used cough suppressant. There are numerous examples of generally used medications which come from varied plant supplies, some of which can often be found right in your own backyard.
