Tectorigenin, an isoflavone present in kudzu, demonstrated antiproliferative activity against human cancer (HL-60) cells. The proposed mechanisms are induction of differentiation in the cells and a reduction in the expression of Bcl-2, an antiapoptotic protein. In addition, isoflavones in Pueraria mirifica are thought to be involved in alleviating symptoms such as hot flashes and night sweats in perimenopausal women and affect cognitive function in postmenopausal women. The isoflavones present in kudzu root extract are also thought to suppress alcohol intake and alcohol withdrawal symptoms in mice although the mechanism is unclear. The anti-inflammatory property of kudzu is attributed to its ability to decrease Prostaglandin E2 and tumor necrosis factor (TNF)-alpha release, both of which are involved in inflammatory process.
