Pharmacognosy by Treese and Evans

Pharmacognosy Trease and Evans
'Trease and Evans' is an encyclopedic reference work on pharmacognosy -  the study of those natural substances, principally plants, that find a  use in medicine. Its popularity and longevity stem from the book's  balance between classical (crude and powdered drugs' characterization  and examination) and modern (phytochemisty and pharmacology) aspects of  this branch of science, as well as the editor's recognition in recent  years of the growing importance of complementary medicines, including  herbal, homeopathic and aromatherapy
