Herbs are the source of pharmacologically active substances that effect the living organism. Dr.Varro Tyler, PhD, ScD, Professor of Pharmacognosy at the Purdue University School of Pharmacy and Pharmacal Sciences, defines herbs as
“crude drugs of vegetable origin utilized for treatment of disease states, often of chronic nature, or to attain or maintain a condition of improved health.” (Herbs of Choice, Pharmaceutical Products Press, 1993.)
It is due to this reason, that the early Romans and ancient Egyptians and Indians used herbs for many medicinal purposes. You have the full blown alternative medical science Ayurveda evolving from these simple techniques of using medicinal herbs to heal people. Modern medicine, investigates the benefits of Herbs through Pharmacognosy – a study of crude forms of plant, animal and mineral medicines.
Even though there have been innumerous herbs discovered with their medicinal properties recognized, but there is still more to come. Scientists are devoted to discovering many more unknown herbs from the world’s rain forests and jungles. Who knows, astounding medical properties of some undiscovered herb might just bring a revolution in the field of medicine.
