Phytoprogestogen
Phytoprogestogens, also known as phytoprogestins, are phytochemicals with progestogenic effects.
Relative to their phytoestrogen counterparts, phytoprogestogens are rare. However, a number have been identified, including kaempferol, diosgenin, apigenin, naringenin, and syringic acid, among others. In addition, 3,8-dihydrodiligustilide from Ligusticum chuanxiong is a potent progestogen, whereas riligustilide is a weak progestogen.
