For four decades, Dr Linda Lancaster's healing knowledge has been available only to her star-studded client list, including Mamma Mia's Amanda Seyfried. In Harmonic Healing, her first book, she shares her lifetime of knowledge with readers for the first time.

In this book, she introduces readers to what she likes to call 'The Invisible Within the Visible', the energetic roots of ill health - caused by toxins, radiations, shock and stress - and how these invisible attacks on the energetic level manifest in the physical, starting in the liver. She also offers a comprehensive, doable and affordable programme to help readers rebalance their health and achieve a state of comprehensive wellbeing.

Dr Lancaster's six-week programme is based on natural ingredients and non-chemical processes, requiring no expensive supplements. Readers will learn how to remove energetic interferences and reclaim their health through positive lifestyle changes, including cleansing foods, detoxifying baths and homeopathic remedies.

Harmonic Healing is co-written with Amely Greeven, New York Times bestselling co-writer of Clean by Dr Alejandro Junger, Primal Fat Burner by Nora Gedgaudas, and Dr Frank Lipman's forthcoming book.
