Indigo Carmine Injection
I have in my hand an ampoule of Indigo Carmine injection - in the small print it is called Indigotindisulfonate Sodium Injection, USP, 0.8% Solution. Same stuff? Moletrouser 15:34, 25 June 2008 (UTC)

What is the relation to carmine (E120)?
1. Does the production of indigo carmine involve animal parts? 2. Will people who react allergically to carmine react stronger to indigo carmine than others? 3. Where are the controversies regarding indigo carmine used as a food additive, knowing that indigo carmine is a skin and respiratory tract irritant? In some Scandinavian stores, they sell "trick caramels" which suddenly colors the lips and tongue blue upon contact with saliva. This effect is based on indigo carmine. — Preceding unsigned comment added by 84.215.243.18 (talk) 08:10, 30 June 2011 (UTC)
