    Near to this point, just below the costal margin on the right side, is where to elicit Murphy's sign as a test for gallstones. Placing a hand here during exhalation and asking the patient to inhale will push the gallbladder against the examiners fingers and elicit a reaction if tender. To confirm pain must not be elicited on the left side too.


    The Front Mu points make likely locations for application of leeches to reduce fevers according to François Broussais' (1772–1838) philosophy who believed in placing them over the diseased organs to reduce inflammation (Greenstone, 2010, The history of bloodletting, BCMJ, Vol. 52, No. 1, Pp 12-14).
