However, its effects in other common conditions, such as the metabolic syndrome, have not been elucidated. Some studies have investigated the effects of SJW extract on differentiation of adipocytes, inflammation, and glucose metabolism. In this review, we summarize these studies and show the following: SJW enhances differentiation of adipocytes via activation of peroxisome proliferator-activated receptor gamma and increases expression of adiponectin; SJW exerts anti-inflammatory effects by inhibiting expression of pro-inflammatory adipokines; and SJW improves glucose metabolism by increasing insulin sensitivity and insulin secretion. Although further investigation is necessary, SJW may help to attenuate the pathologic process associated with the metabolic syndrome.
