Researchers at the University of Maryland, Baltimore, used a roundworm that has some genetic and biochemical similarities to humans to examine complex herbal preparations thought to combat adverse effects of aging. The worms, called Caenorhabditis elegans, or C. elegans, have a brief life span (about 20 days). In an NCCAM-funded study, researchers assessed two traditional Chinese multiherbal formulas—Huo Luo Xiao Ling Dan (HLXL), taken for chronic inflammatory pain (e.g., joint pain from arthritis); and Shi Quan Da Bu Tang (SQDB), taken to reduce fatigue and improve general wellness. They found that cinnamon bark, a component of both formulas, increased the worms’ life span.
