"The Complete Herbal" by Nicholas Culpeper is a 17th-century guide that blends herbal medicine, astrology, and early medical practices to explain how plants can treat human illnesses. The book works as a manual for herbal treatments and a study of the natural ideas behind herbal medicine. Culpeper presents his book and cautions readers against relying on inaccurate versions that have been released, and stresses the importance of understanding the 'why' behind the properties of herbs, something he says traditional authors often missed. Culpeper shares his history in herbalism and astrology, arguing that true understanding comes from reason and experience, not old customs. The start prepares a way to understand herbs and their uses, asking readers to think about the link between space and physical health.
