Query: My gums are sluffing off, my taste is almost gone...after 3 days!

I've used this product 4 times in the last 3 days. My gums first started to die and peel away ONE HOUR after I first used the product. I didn't know what it was, so I used it a few more times, each time thinking, "Surely this product woudln't be on the market if it was that bad..." This morning, sheets...SHEETS of my gums peeled off! Gross, white, slimy, dead mucous membranes all over my mouth. To make things worse, my taste is nearly gone and my allergies have been killing me!DONOTBUYTHISPRODUCT!
