The use of plants and plant extracts for medicinal purposes has until recently been based on folk lore and superstition. Knowledge of which plant to use and how to use it has been passed from generation to generation for as long as man has been around. Although much of this information was valid there was also a plethora of plants used that either had no effect at all or in some cases even the opposite effect from that desired. It is only in the last century that some scientific research has occurred to validate or dismiss the efficacy of medicinal plants. In some cases a particular substance or plant led to the development of conventional drugs and medication after extensive research; in other cases the studies were superficial and mostly biased towards "proving" or justifying claims of efficacy. These pages reflect the information we have have gathered from diverse sources and it is unfortunate that in most cases we cannot vouch for the validity of the information. Even today more than half the population of our planet relies exclusively on herbs, plants and other extracts from nature for the treatment of all diseases. In almost all of these cases the practice is as a consequence of thousands of years of trial and error with very little scientific validation. Isolating individual constituents (the chemical ingredients found in the plant) to determine which substances are responsible for the desired effect is still in its infancy with only a small percentage of these substances fully analyzed. This is an index to the constituents of plants and other substances that occur in nature. It is by no means complete and in many cases inaccurate but it is the best information we have been able to find at this stage. We are constantly updating and expanding on the information.
