Benefits of Essential OilsVetiver, ginger and patchouli will be grounding and earth-connecting while sandalwood and cedarwood are stabilizing, strengthening and centering–all of these essential oils will help with balance and stability in your yoga poses.
Myrrh, frankincense, eucalyptus and rosemary encourage the flow of energy, self-expression and help you achieve steady, deep inhalations and exhalations. (Mastering your breathing process is as important to successful yoga practice as the poses.)
Lavender, geranium and chamomile are calming and relaxing.
Bergamot, lemon and orange lend a sense of fulfillment and spiritual nourishment to your yoga quest.
Neroli, jasmine, ylang ylang and rose promote transcendence and spiritual expression.
