Aromatherapy is the art of using the essential oils extracted from plants both for healing purposes and for improving quality of life. Essential oils have been used since the dawn of mankind for healing. Some of them, such as myrrh, frankincense, hyssop, and so on, are mentioned in the Bible. They are all antiseptic, without exception, as well as fungicidal, viricidal, and anti-inflammatory. They do not have the side-effects found in synthetic medications; perhaps this accounts for the renewed interest in natural healing.
