The English physitians guide: or a holy-guide, leading the way to know all things past, present and to come : to resolve all manner of questions, viz. of pleasure, long-life, health, youth, blessednes, wisdome and vertue ... and teaching the way to change, cure and remedy all diseases

Attributed to John Heydon, this work exemplifies the seventeenth-century blending of medicine, prophecy, astrology, and occult philosophy. Historically, it shows how early modern readers sought universal cures and predictive knowledge through esoteric methods, and the text offers practical-seeming advice mixed with visionary speculation.

John Heydon (1629–c. 1667) was an English writer on astrology, magic, and Rosicrucian themes. His works, including The English Physitian and other treatises, exemplify seventeenth-century occult prose that blended Hermetic, astrological, and visionary traditions.
