Liang, M. T., Podolka, T. D., & Chuang, W. (2003). Panax Notoginseng supplement improves endurance and oxygen uptake but not skin blood flow. Medicine and Science in Sports and Exercise, 35(5), Supplement abstract 1486.

Ss were assigned to an experimental group (N = 17) or placebo-control (N = 17). Experimental Ss were give 450 mg of Panax Notoginseng in capsule form and placebo Ss were given starch. Doses were administered three times daily for 30 days. A maximum cycle ergometer test at a constant load was used to gather data.

Panax Notoginseng ingestion improved time to exhaustion and decreased VO2 and minute ventilation at the 24th minute of exercise. Other variables were not affected by the supplement nor did they change in the placebo condition. Skin temperature and skin blood flow were not affected.

Implication. Panax Notoginseng ingestion prolongs exercise to exhaustion and reduces VO2 and minute ventilation. Skin temperature and skin blood flow are not affected.
