Instruct: Classify Amazon reviews into positive or negative sentiment
Query: The first negative review I have ever written

The product description and ingredient list above are bizarre because they are both far from the truth. The ingredient list on the back of the bottle says that it contains saccharin, CI 42051, which a synthetic blue dye that is actually banned in the U.S. because it induces an allergic reaction, CI 16255, which a synthetic red dye that is banned in the U.S. because it is carcinogen, and CI 19410, which is a synthetic yellow dye. This product should be banned. If someone corrects me, I will remove this review. I am going to try to get my money back from the seller. We will see what happens.
