Devil's Club Root - Oplopanax: A close cousin to Ginseng. Devil's club main use is as a safe and effective expectorant and respiratory stimulant. It works by increasing bronchial secretions as well as helping to soften hardened bronchial mucus so it can be coughed out with greater ease. In addition, Devil's club has proven helpful for people suffering from Rheumatoid arthritis and other autoimmune disorders, especially while they are in remission and with accompanying modifications to the diet. Its usefulness in this context seems to lie in its ability to recalibrate the outside extremes of tolerable metabolic stress. Parts Used Bark of stem roots and bark of true roots as well as heartwood of true roots
