In 1911, Fr. Johannes Künzle published what would become one of the most important books written on Herbal Medicine in the 20th Century. This bold and outspoken Swiss priest wrote what was little more than a pamphlet on herbs and their use. His brief booklet, of fewer than 40 pages, sought to educate the common people of central Europe about the flowers, weeds and trees that grew in abundance, and how they may be used to treat common illnesses. Like his predecessor, Fr. Kneipp, his vision was of kitchen medicine, folk medicine, and a firm faith that God had provided all an individual of family could need for general health in the “Herbs and Weeds”. His little book became a best seller. This led to fame that he generally did not desire, and to clashes with the medical establishment. He challenged that establishment and won court battles, proving that his herbs were sometimes even more effective than their medicine. This made Fr. Künzle an international figure.
