Fragrant oils have been used for thousands of years to lubricate the skin, purify air, and repel insects. Ancient Egyptians used fragrant oils for bathing and massage. Essential oils of plants have been used medicinally through application directly to the skin (usually diluted), as a part of massage, added to bathwater, via steam inhalation, or in mouthwashes. Aromatherapy is a technique in which essential oils from plants are used with the intention of preventing or treating illness, reducing stress, or enhancing well-being. Fragrance oils and products containing man-made compounds are not used in the practice of genuine aromatherapy. Although many gift shops sell scented candles, pomanders, and potpourri as "aromatherapy," genuine aromatherapy treatments use higher strength (concentrated) essential oils drawn from various herbs. There is no formal training or licensing procedure for aromatherapists in the United States. This technique is offered by a wide range of practitioners with licenses in other fields, including massage therapists, chiropractors, and other therapists.
The practice of acupuncture originated in China 5,000 years ago. Today it is widely used throughout the world and is one of the main pillars of Chinese medicine. There are many different varieties of the practice of acupuncture, both in the Orient and in the West. The most common forms available to westerners are as follows. Traditional Chinese medicine (TCM) usually combines acupuncture with Chinese herbs. Classical acupuncture (also known as five element acupuncture) uses a different needling technique and relies on acupuncture independent of the use of herbs. Japanese acupuncture uses smaller needles than the other varieties. Medical acupuncture refers to acupuncture practiced by a conventional medical doctor. Auricular acupuncture treats the entire body through acupuncture points in the ears only. Electroacupuncture uses electrical currents attached to acupuncture needles. Aside from needles, other methods of stimulation are also considered forms of "acupuncture." These include the use of heat from the burning of herbs placed on specific points ("moxibustion") and the placement of herbal pastes on specific points. Research on the effectiveness of acupuncture has special challenges. These include the diversity of approaches, the practice of individualizing treatment for each patient, differing skill levels between practitioners, and difficulty separating out the effects of acupuncture from placebo effects (i.e., how the patient's beliefs and expectations affect his/her perception of symptoms). Based on acupuncture's long history of use as well as the limited research available, both the World Health Organization and the National Institutes of Health have identified many conditions for which it may be recommended. However, many common uses do not yet have formal scientific evidence to support them.
