| The first generally accepted use of
plants as healing agents were depicted in the cave paintings
discovered in the Lascaux caves in France, which have been
Radiocarbon dated to between 13,000 - 25,000 BCE.. Over time and
with trial and error, a small base of knowledge was acquired within
early tribal communities. As this knowledge base expanded over the
generations, tribal culture developed into specialized areas. These
'specialized jobs' became what are now known as healers or Shaman.
Plants have an almost limitless ability to synthesize aromatic
substances, most of which are phenols or their oxygen-substituted
derivatives such as tannins. Most are secondary metabolites, of
which at least 12,000 have been isolated, a number estimated to be
less than 10% of the total. In many cases, these substances (esp.
alkaloids) serve as plant defense mechanisms against predation by
microorganisms, insects, and herbivores. Many of the herbs and
spices used by humans to season food yield useful medicinal
compounds.
The use of herbal life vitamins and search for drugs and dietary supplements derived
from plants have accelerated in recent years. Pharmacologists,
microbiologists, botanists, and natural-products chemists are
combing the Earth for phytochemicals and leads that could be
developed for treatment of various diseases. In fact, many modern
drugs have been derived from plants.
