"Culpeper attempted to make medical treatments more accessible to laypersons by educating them about maintaining their health. Ultimately his ambition was to reform the system of medicine by questioning traditional methods and knowledge and exploring new solutions for ill health.... He was one of the most well-known astrological botanists of his day,pairing the plants and diseases with planetary influences, countering illnesses with nostroms that were paired with an opposing planetary influence. Combining remedial care with Galenic humoral philosophy and questionable astrology, he forged a strangely workable system of medicine; combined with his "Singles" forceful commentaries, Culpeper was a widely read source for medical treatment in his time" (Wikipedia article on Nicolas Culpeper, accessed 01-2017).
