Derived from flowering plants to augment the effects of colour in healing, the use of essential oils is also an ancient practice. Today an increasing number of people combine colour and aromatherapy in healing.

As scientific research yields greater understanding of subtle energies and their relevance to health and well-being it is likely that ancient healing practices involving colour will become more widespread, and that their use in orthodox medicine will become more accepted as the scientific community itself becomes more ‘enlightened’.
