I recently had a chance to review The Essential Step-By-Step Guide to Acupressure with Aromatherapy Treatments: Relief for 64 Common Health Conditions. This book provides a comprehensive look at acupressure and aromatherapy and how they can be used for a wide variety of conditions. The points are all easily explained, with pictures and with specific explanations on how to find the precise points on the body (since every body's body is slightly different). Then, many different conditions are listed, each one with the primary and secondary points that will help relieve the conditions, along with appropriate aromatherapy treatments.
While I don't believe that every single condition can be treated using alternative medicines like acupressure or aromatherapy, I do think that they can help with many different health conditions. They also can work in conjunction with traditional treatments (just be sure to let your health practitioners know about any alternative therapies you are also using).
