“…The approaches have predominantly been studied using open-label and/or uncontrolled study designs and small sample sizes with no random assignment, making it difficult to draw conclusions about efficacy Kwekkeboom et al, 2010;Shneerson, Taskila, Gale, Greenfield, & Chen, 2013). Despite the limitations and with acknowledgment that inclusion of controls such as double-blinding presents methodologic challenges (Elam, Carpenter, Shu, Boyapati, & Friedmann-Gilchrist, 2006;Visser et al, 2011), further testing of these complementary approaches seems warranted.
