All the oils obtained from the seeds or pericarps of vegetables, without distillation, and which are viscid, but slightly odorous and sapid; lighter than water, and insoluble in alcohol. The rancidity of oils depends on the absorption of oxygen, and therefore they should be kept in bulk as much as possible, and in narrow-necked bottles, so that a very small surface only can be exposed to the air. All the fixed oils are emollient, and, in a certain dose, they act as purgatives and emetics. They are prepared by expressing the fruit or seed containing them.
