The College of Practitioners of Phytotherapy (CPP) is a professional membership organisation of phytotherapists that sets the highest standards of practice in herbal medicine.

Phytotherapists (‘phyto’ means ‘plant’ in Greek) are dedicated herbal practitioners with specialist university training. They combine orthodox medical knowledge and skills with scientific understanding of plant medicines.

Concern for a solid and credible scientific basis in medical herbalism and for professional standards in practice led Hein Zeylstra, a prominent herbalist and the founder of the School of Phytotherapy, to establish a professional body in 1991. Today, the CPP continues to set the standard worldwide as the body for ensuring the highest quality research, education and practice. All members are required to participate in a professional training scheme updating them with the latest scientific developments. The CPP exists to protect the public interest and it continually monitors its members as to their fitness to practise. It has members in 11 countries including Australia, South Africa, Canada and the USA.
