Shown below are 72 plants selected from the CEBTech Services Herbarium that have been shown by previous investigators to produce biochemicals that could be of industrial or medical importance. Other investigators have found that many of these plants have been used as native medicinal constituents for reliefs and cures for hundreds of years. This has been accomplished historically without knowledge of the biochemical composition of the plant material being used. It is recognized that the biochemicals, as of yet isolated from certain plant material, are not necessarily responsible for any remedies associated with that plant material.
In a sense, the exploration of medicinal plants of Western North America is still in its infancy. The ecological diversity forced by harsh environmental extremes has stimulated the evolution of secondary metabolites - chemical compounds that have biological effects in humans - which are yet to be discovered in many plants. This is because the vast majority of plant species have not been adequately investigated for biologically active chemicals (88).
The CEBTech Services Herbarium contains greater than 200 flowering plants collected from the Northwestern Plains (South Dakota) and Rocky Mountains (Wyoming) of the United States.
