How medicines work, sentence 3

New medicines are tested in labs, then in careful trials with volunteers, and checked by regulators before doctors can prescribe them; even natural doesn't always mean safe.

Who acts: doctors, natural · What happens: test, check, prescribe, not mean · To what, where: New medicines, labs, medicine

The frames are read from the tree by Mova's frames reader (prag) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
