Ranunculales, plants that sedate ...

With their often toxic substances, Ranunculales tend to have the effects of a depressant. Among these are the opium-containing poppy, medicinal plants such as black cohosh with its menstrual-regulating effect, and extremely toxic plants such as aconite. The generally herbaceous plant order contains about 4,000 species and is found worldwide. The poppy and black cumin are two of its most economically relevant products.
