Being sickened by the taste, smell or even thought of a particular
food or drink because, on a previous occasion you became ill shortly after consuming it. Your mind has made a connection between the
food/drink and the illness although it was purely coincidental, and the
food/drink item actually was not the cause of the illness.
You are dining on steak with Sauce Bernaise. Shortly after eating it you become violently
ill. In fact you came down with the flu, and you would have become
ill just then regardless of what you
ate. Nevertheless, your mind connects the illness with the sauce bernaise, and ever after whenever you taste, smell, see or
even think of sauce bernaise your stomach gets queasy because you think it was what caused you to get ill.
