5. Is Cuban oregano toxic?

Is Cuban oregano toxic? This is the last thing everyone cares about. Although the fragrance it gives off is aromatic, everyone worries about whether it is toxic like some other plants. Here we tell everyone that the reason Cuban oregano gives off fragrance is similar to the principle behind the mimosa's "shyness": when it is stimulated by outside touch, the water within its cells acts, and the turgor pressure of the pulvinus changes. The only difference from the mimosa is that under the effect of turgor pressure it does not contract; instead, the stomata used for internal air exchange expand, and a volatile substance with an apple fragrance diffuses through the stomata into the air. The fragrance of Cuban oregano is a green substance of the plant's own cells, non-toxic and harmless. Cuban oregano is not toxic.
