Beth root (Trillium erectum). Also known as birthroot, it is used in herbal medicine as a gynaecological tonic. Its affects may be due to steroidal saponins, which can have hormonal effects on the body. Native North Americans used it for inducing labour, controlling vaginal discharge and post-partum bleeding.
