If the body's cells lack the necessary quantities of tissue salts and/or have difficulty accessing, absorbing or utilizing them, cell metabolism becomes disturbed and disease arises. When given in a potentised and microscopic amount the tissue salts are more easily absorbed into the cells and tissues of the body. The tissue salts can be rapidly brought back into proper balance in the cells, thus alleviating the symptoms and healing the deeper causes of disease. Mark Wells's 40 years of prescribing tissue salts in private practice has enabled him to write this book not only as a guide for other health practitioners but also for anyone who wishes to confidently and safely prescribe tissue salts for themselves and their loved ones. Tissue salts have also proved to be a 'God send' for many parents with infants and young children. Having tissue salts available to give to their children empowers parents to take more control and responsibility for their children's health. This book guides parents in their use in a straight-forward, and always safe and responsible way. This book has been a best seller ever since it was first published in 1995.
