Medicine Plants by Malcolm Mills from Castle Gardens

 A full house for Malcolm’s talk on Medicine Plants. Malcolm, from Castle Gardens in Sherborne, gave us a very comprehensive talk with many examples, below is a summary.

Many plants (including fungi) produce compounds that we use for medicinal uses, otherwise knows as alkaloids – powerful complex chemicals.

Why do plants produce alkaloids? Some reasons include:

  • To protect them from predators
  • To prevent rotting in damp growing conditions
  • May encourage healing after damage and stop infections…

Plants have been used for medicinal purposes for 5-6000 years, Otzi the frozen mummy found in the Alps, had a medicine kit with him containing birch fungus. Egyptians made the first pills using clay as a base medium then mixing in Opium or Myrrh.

All medicines ending in “ine” are derived from plants, for example morphine, caffeine, nicotine..

Only about 20% of all plants in the world have been tested for medicinal use therefore it is most important that biodiversity (including the rain forests) is preserved as it is highly likely that cures are held in the gene pool.

40-50% of plant medicines are derived from plants (although many are now synthesised).

80% of the world still relies on plant medicine for health and well-being.
