College of Practitioners of Phytotherapy
The College of Practitioners of Phytotherapy (CPP) is a British professional organisation for herbalists. Phytotherapy is a term often used as a synonym for medical herbalism. The herbalist Hein Zeylstra established the CPP in 1991 from a desire to provide medical herbalism with a credible and rational basis through training and research as well as in practice. Members of the CPP are required to have a recognised qualification in medical herbalism and the body conducts continuing professional development with its members in order to ensure that the practitioners are aware of the latest developments in  the field. They recognise the importance of protecting the public interest in this regard and have members in eleven countries, mostly in the Anglophone world. They provide ongoing professional training for herbalists and other healthcare workers, a register of members, an online resources library and professional indemnity insurance.
