Smeltzer, K. D., & Gretebeck, R. J. (1998). Effect of Radix Acanthopanax Senticosus on submaximal running performance. Medicine and Science in Sports and Exercise, 30(5), Supplement abstract 1578.

Radix Acanthopanax Senticosus (Ciwujia -- trade name Endurox) has been marketed as an ergogenic aid that enhances endurance performance by increasing fat utilization and decreasing heart rate during exercise. In a single-subject ABAB experimental design, it was found that the substance had no measured impact on endurance performance or metabolic characteristics. In addition, RER values remained unchanged.

Implication. Radix Acanthopanax Senticosus (Ciwujia) has no effect upon submaximal endurance performance.
