In recent years there have been a number of significant developments of natural products for the treatment of rheumatic diseases, pain and gastro-intestinal ulcers and inflammation. The volume covers some of these novel developments of natural products which are of current and future interest as therapies for the above-mentioned conditions. Most available volumes cover a wide range of biological and technicological aspects of natural products and their discovery, some involving synthesis and properties of chemical compounds. The difference in this volume is that the natural products have a focus on their therapeutic effects on pain, arthritic and gastrointestinal diseases. Some of the natural products covered are either at the experimental stage of development while others are well-established clinically-used products. Each has its own unique place in therapy.
