Acupuncture significantly reduces levels of a protein in rats linked to chronic stress, researchers at Georgetown University Medical Center (GUMC) have found. They say their animal study may help explain the sense of well-being that many people receive from this ancient Chinese therapy.

Published online in December in Experimental Biology and Medicine, the researchers say that if their findings are replicated in human studies, acupuncture would offer a proven therapy for stress, which is often difficult to treat.

When given alongside radiation therapy for head and neck cancer, acupuncture has shown for the first time to reduce the debilitating side effect of xerostomia, according to new research from The University of Texas MD Anderson Cancer Center and Fudan University Shanghai Cancer Center.

The study, published in the journal Cancer, reported findings from the first randomized controlled trial of acupuncture for the prevention of xerostomia.

Spas that offer massage therapy using fragrant essential oils, called aromatherapy, may have elevated levels of potentially harmful indoor air pollutants such as volatile organic compounds (VOCs) and ultrafine particles, according to an article in Environmental Engineering Science, a peer-reviewed journal published by Mary Ann Liebert, Inc.

Fragrant essential oils, derived from plants, may release various VOCs into the air. VOC degradation caused by the reaction of these compounds with ozone present in the air can produce small, ultrafine byproducts called secondary organic aerosols (SOAs), which may cause eye and airway irritation.

Complementary and alternative medical (CAM) treatments such as herbal supplements have become increasingly popular in the United States, especially among older patients and those with chronic pain. However, many of these products can have serious and potentially harmful side effects when combined with medications prescribed during and after surgery, according to a review article in the Journal of the American Academy of Orthopaedic Surgeons (JAAOS).

A physician on a medical relief mission to Africa sees pregnant women sip a medicinal tea prepared by local witch doctors when the time for birth arrives. Made from the leaves of a plant called "kalata-kalata," the tea speeds labor and delivery. Scientists analyze the plant and discover a remarkable new substance. The research puts them on course for discovery of potential new drugs for diseases that affect millions of people worldwide.

The study is the first to look at the effects of yoga on cortisol levels in women with fibromyalgia. The condition, which predominantly affects women, is characterized by chronic pain and fatigue; common symptoms include muscle stiffness, sleep disturbances, gastrointestinal discomfort, anxiety and depression.

Previous research has found that women with fibromyalgia have lower-than-average cortisol levels, which contribute to pain, fatigue and stress sensitivity. According to the study, participants' saliva revealed elevated levels of total cortisol following a program of 75 minutes of hatha yoga twice weekly over the course of eight weeks.

The fruit of the saw palmetto tree does not relieve symptoms of an enlarged prostate, even when men take the herbal supplement in very high doses, a new study shows.

The research was published Sept. 28, 2011, in the Journal of the American Medical Association.

Many older U.S. men take saw palmetto extract in an attempt to reduce bothersome symptoms of a swollen prostate, including frequent urination and a sense of urgency. Its use in Europe is even more widespread because doctors often recommend saw palmetto over more traditional drug treatments.

Oils can have several protective benefits for all skin and body types. However, deciphering which oils to use for which skin type can be confusing. Aimee Masi of the Loyola Center for Aesthetics works with her patients to tailor a beauty regimen that is appropriate for their skin. She recommends both common and essential oils that repair the skin and restore the body without clogging pores.

"Oils have been used for centuries for their beauty and healing properties," Masi said. "There are numerous advantages to incorporating oils into a skin-care and health regimen."

Yoga is commonly seen as a practice beneficial to body and mind. Increasingly, yoga is being taken a step further and applied as a form of complementary and alternative medicine in treating psychiatric disorders.
