The ancient records of natural products from Mesopotamia (2600 B.C.) were delineated on clay tablets in cuneiform which documented oils from Cupressus sempervirens (Cypress) and Commiphora species (Myrrh) which are being used till date to treat coughs, colds and inflammation. An Egyptian pharmaceutical record, The Ebers Papyrus (2900 B.C.) has documented over 700 plant-based drugs ranging from gargles, pills, infusions, to ointments. Arabs were the first people to own private pharmacies (8th century) with Avicenna, a Persian pharmacist, physician, philosopher and poet, volunteering much to pharmacy and medicine through works such as the Canon Medicinae [3].
