Culpeper (or Culpepper), Nicholas (1616–1654)

English medical writer and astrologer. He practised as an astrologer and physician in Red Lion Street, Spitalfields, London, from 1640. He is best known today for The English Physician Enlarged, or the Herbal (1653), widely used by herbalists.

In 1649 he issued A Physicall Directory, an unauthorized translation of the College of Physicians' Pharmacopoeia, which aroused criticism and anger from the College for the infringement of the monopolies of medical writers.
