Abstract:
:This paper examines the various methods that are available to the scientist working with natural materials to substantiate their efficacy. The methods discussed are: literature surveys, clinical trials, instrumental measurement, products with Pharmaceutical Licenses, comparison with other plants containing same active chemicals, and comparison of benefits with related members of the same family. Examples are given using the Compositae family as a primary model, other examples are given quoting the Labiatae, and Solanaceae families.
