Tyler, Ph.D., professor of pharmacognosy, which is the study of drugs from natural sources, at the location of Purdue University in West Lafayette, Indiana.
It has been scientifically researched and also proven that the following medicinal herbs had withstood detailed scrutiny in studies done in Europe, Asia as well as North America.
These medicinal herbs are chamomile, echinacea, feverfew, garlic, ginkgo, lemon balm, milk thistle, st. John's wort as well as valerian.
History has shown that the scientific evidence of herbs was eminent. Doctors and scientist were were able to isolate the active ingredient from any medicinal herb and manufacture a more powerful, natural and curative medicine.
A German apprentice pharmacist was able to isolate active substance of the opium plant. This is a chemical alkaloid, which he called morphine. This was followed by other isolation of ingredients from herbs which include, the heart drug digitoxin taken from purple foxglove leaves as well as the anesthetic cocaine taken from the coca leaves.
