"In the mid-seventeenth century, England was visited by the four horsemen of the apocalypse : a civil war that saw levels of slaughter not matched until the Somme; famine in a succession of failed harvests that reduced peasants to "anatomies"; epidemics to rival the Black Death; and infant mortality rates that emptied crowded households of their children. In the midst of these terrible times came Nicholas Culpeper's Herbal - one of the most popular and enduring books ever published." "Culpeper was a virtual outcast from birth. Rebelling against a tyrannical grandfather and the prospect of a life in the Church, he abandoned his university education after a doomed attempt at elopement. Disinherited, he went to London, Milton's "city of refuge, the mansion house of liberty." There he was to find his vocation as an herbalist - and as a revolutionary." "London's medical regime was then in the grip of the College of Physicians, a powerful body personified in the "immortal" William Harvey, anatomist, royal physician and discoverer of the circulation of the blood. Working in the underground world of religious sects, secret printing presses and unlicensed apothecary shops, Culpeper challenged this stronghold at the time it was reaching the very pinnacle of its power - and in the process became part of the revolution that toppled a monarchy."--BOOK JACKET.
