Effect of auricular acupressure on postpartum blues: A randomized sham controlled trial.

Aim: To investigate the effect of auricular acupressure on the severity of postpartum blues.

Methods: A randomized sham controlled trial was conducted from February to November 2021, with 74 participants who were randomly allocated into two groups of either routine care + auricular acupressure (n = 37), or routine care + sham control (n = 37). Vacaria seeds with special non-latex adhesives were used to perform auricular acupressure on seven ear acupoints.
