Is this like Lugol's?
At the local grocery store, I stumbled on two little bottle of "Iodine Tincture USP" and I'm wondering if this is like Lugol's. Under active ingredients it says, "Iodine tincture U.S.P. 100% (2% iodine)...... First aid antiseptic. It doesn't say what else is in it, no secret peel-back label, and the product's website was minimal and unhelpful. Naturally the bottle declares it for external use only, with a cute little red scull and crossbones on the front of the label. Is the USP 100% some kind of standard wherein it would be possible to ascertain any additional unmentioned ingredients?
This is one of those mysterious happenings, actually. I was wandering through town aimlessly, and figured I'd wander through the grocery store. I was feeling very aimless. Looking through the shelves of pharmacy offerings I began looking for items Ted had mentioned. Potassium Citrate contained sucrolose..... I perused the shelves for several minutes. Then, stashed behind some hanging items were two little bottle of iodine, similar to the kind I'd been meaning to buy online. I failed to find the price on the shelves, as well as any additional bottles. The clerk scanned them at about $3 each. I felt less aimless. Went home.
EC: Don't think so...
