Herbal medicine involves the use of whole plants to promote health and treat disease, drawing on a tradition of human use for over 60,000 years. It views disease more broadly by addressing underlying causes and individual expression rather than just symptoms. Herbal medicines are prescribed to restore homeostasis and promote optimal cellular nutrition and elimination. Around 1 in 5 people in the UK regularly use herbal medicine, and it is regulated through organizations like the National Institute of Medical Herbalists. Herbal medicines are prescribed individually based on a comprehensive medical history and clinical examination.
