This paper, the second part of a two part series, continues to explore the historical literature and legal instruments that shaped the present status of British Herbal Medicine as an unorthodox medical practice. This review commences at the advent of World War 1 examining how this landmark in history affected the role Herbal Medicine had to play in society. The ensuing parliamentary debates and enactment of medical legislation in the post war years that further shaped the fortunes of Herbalists as state sanctioned medical figures are explored, finally showing how in the 21st century European legislation ultimately influenced the future and status of Herbalists in Britain.
