Allegra (fexofenadine) allergy: I am not quite sure of the question. Allegra (fexofenadine) is a non drowsy antihistamine to treat symptoms of allergic or non allergic rhinitis. The symptoms include runny stuffy nose, sneezing, itchy and watery eyes. It can also help itching of the skin.
Most fruits also contain MSM, but no sulfur from cysteine or methionine, because there is hardly any protein in fruits. MSM has also been found in tea, coffee, beer and port wines. It is not easy to determine sulfur content in foods because the amounts depend greatly on the quality of soil and farming practices.
Inulin is present in high concentrations in chicory root, agave and even dandelions. It is present to a lesser extent in bananas, wheat, onions, asparagus, rye and barley. Indeed, it has been found in over 36,000 plants around the world. Oligofructose, also present in these foods, is a similar fiber.
