We invite you to embark with us on a journey that is truly special and profound.  This journey connects us with cultures and civilisations that have come before us – connects us with our own living heritage – the healthcare tradition that is Tibb [Whole-Person Healthcare & Medicine].

Through this wisdom-based healing tradition, you will have the opportunity to access valuable treasures of self-knowledge, and unlock pathways to better health and wellbeing. We trust this will be an inspiring, insightful, and educational journey for you.

You may register for our online programmes to improve and enhance your own health, and help your family and friends. If you wish to become a herbalist, naturopath, iridologist, and/or psychotherapist, you can enrol on our in-person professional trainings.

Tibb: Whole-Person Healthcare and Medicine

Tibb is a tradition of health which was synthesised in the crucible of the Middle East, and integrated elements from Egypt, India, China and classical Greece. ‘Tibb’ is an Arabic word, which in different places has been referred to as Arabic, Greco-Arab, Hikmah, Unani, Islamic and Sufi medicine.
