Naturopathy Diploma
Naturopathy Diploma

The Naturopathy diploma course offered by the School of Natural Medicine, UK integrates the study of Naturopathy, Healing Diets, Herbal Medicine and Iridology.

Naturopathy is a systemic approach to holistic natural medicine that recognises that the cause and cure of disease lies within the whole person; physical, mental, emotional and spiritual. Naturopathy works with natural laws of living, and the principles of cleansing, rejuvenation and transformation to create effective programmes that integrate diet and lifestyle changes with emotional healing, supportive naturopathic therapies for acute and chronic conditions, cleansing, healing processes, exercise, breathing, behavioural therapy, awareness of relationships, the environment, and more.

I feel extremely well prepared from my studies to work professionally with clients. To begin with I was very nervous. I have found that once I begin the consultation the course has prepared me so well that I know exactly what to do and the consultation flies by with ease. I really enjoy working with people 1-1 and I find their lives fascinating! I am well prepared to ask the right questions and give good, effective recommendations from the well put together course. Thank you so much!!! …I would definitely recommend this course to anyone and I don’t think I could have chosen a better school to study with. It has been perfect for me on all levels and I feel so much love and gratitude for my teachers.
