Origin of Herbal Medicine
• 60 000 BCE, was the discovery that the dead huminidae (great apes) seemingly had been laid to rest with bunches of flowers that would have grown in the area at the time
• The African great apes, which appear to use several plants for strictly therapeutic purposes (Huffman et al. 1998)

Western Herbal Medicine
• The oldest written reference to medicinal plants and their use is the Chinese Pen Ts’ao, written about 4800 years ago and listing more than 360 species of herbs
• Another ancient manuscript, the EbersPapyrus from Egypt, dates from about 1500 BCE and mentions a large number of plant and animal remedies
![Page 23: Herbal Medicine - Biomedic Generation · –make students aware of the bounty of Allah ... Introduction to Herbal Medicine 2. ... Visit to Herbal Farm/Medicinal plant](https://reader030.vdocuments.us/reader030/viewer/2022021423/5ad75f0c7f8b9af9068c1e81/html5/thumbnails/23.jpg)
• Hippocrates (c.460–377 BCE) of Greece is often referred to as ‘the father of medicine’. He could equally be regarded as one of the founders of holistic herbal medicine.
He prescribed individualised treatments for his patients, recommende exercise and dietary regimens and selected his herbal treatments from more than 400 species of plants.

• Diocles, a student of Aristotle, wrote the oldest Greek herbal, the Rhizotomika, in the fourth century BCE
• Galen (c. 129–199 CE), like Hippocrates, practised humoral medicine but his approach to therapy was rigid, quite unlike the flexible and individualisedapproach of Hippocrates.

• In England, John Gerard’s famous Herbal or General Historie of Plantes was published in 1597, and in 1649 the apothecary Nicholas Culpeper (1616–54) translated the London Pharmacopoeia from Latin into English, much to the consternation of the medical establishment, who saw this as a threat to their exclusive medical knowledge
