One of the best known forms of acupressure is Shiatsu. Acupuncture points are located along a network of 14 main meridian lines, or channels, through which the body's energy flows. Acupuncture is said to stimulate the body's natural healing abilities, relieve pain and restore internal regulation systems. Aromatherapy is a branch of herbalism in which distilled essences of plants, called essential oils, are used for easing the symptoms of a wide variety of ailments. The essential oils are extracted from the bark, leaves, petals, resins, roots or stems of certain aromatic plants, and are used in massage, in bathing, or through inhalation.
Aromatherapy is also for skin beauty care and perfumes.
Chiropractors use neither drugs nor surgery. Their most commonly used therapy is manual adjustment, or manipulation, of the spine and extremities and nerves. Herbal products are derived from roots, stems or leaves and are frequently sold in liquid extract, pill form, or as teas. Herbalists use herbs to strengthen the body and assist its natural ability to heal itself. That is, a substance that would create symptoms of disease in a healthy person is said to trigger the immune system of the ill person.
