Medicinal plants contain a wide array of chemical compounds. They have a distinct order to their perfection. Natural selection pressures push these plants to "try out" variations on molecules to enhance the plant's odds of surviving stressful environments. So, often, one molecule is present in the greatest amount and has the most dramatic effect in a human body -- but along with it are variations of that molecule in the same plant.

Human beings and plants have co-evolved for millions of years, so it makes perfect sense that our complex bodies would be adapted to absorb needed, beneficial compounds from many varieties of complex plants and ignore the rest. However, no plant should be ignored when it comes to advancing human health.
