We recommended the New Zealand book Complementary Therapies for Cancer by Professor Shaun Holt.
This resource contains evidence-based advice on many complementary therapies such as acupuncture, massage and mind-body interventions like meditation, yoga and hypnosis.
It examines the effectiveness of herbal remedies including St John’s Wort and ginger, and examines many commonly used therapies which are unlikely to help, or can even cause harm.
