This text begins with the theoretical foundations of aromatherapy, including the five elements, yin and yang, and the connection between astrology and essential oils. Attractive illustrations complement an outline of the distillation process for producing essential oils, a chart of application methods, and eighteen steps for a full body sequence of aromatherapy massage. Forty essential oils are included in an alphabetical materia medica, with a review of each essential oil that explains its energy, main element, aroma, health properties, safety information, and preparation methods. Oils include yarrow, sandalwood, lemon, lavender, rose, clary sage, cypress, ginger, fennel, peppermint, caraway, palmarosa, everlasting, bergamot, hyssop, tea tree, rosemary, and patchouli. The text further explains how to effectively blend oils to restore balance and treat or prevent conditions such as depression, indecision, disempowerment, frustration, anger, lack of self-esteem, poor concentration, apprehension, anxiety, worry, agitation, and nervousness. This beautifully illustrated text provides a wealth of information for anyone learning aromatherapy to balance emotional, physical, and mental health.
