Several plants, such as Podophyllum, will cause birth defects. This is the primary listing, and reflects a combination of current botanical usage, older pharmaceutical Latin names, and common usage. Leptandra is called Veronicastrum in current botany, but the first name still is widely used by herbalists and that is how it is listed here. Others are carefully specified by species because of distinctly different aspects between them. Some plants are so singular, like Anemopsis, that only one name is used to define them.
