Urine therapy is older than any other therapy listed on this page of remedies (look it up and see it's history). I second using this therapy as a safe and VERY viable alternative to OTC and prescription medications. Once you're over the stigma, you'll see it works. Narrow mind = sick.
Two of my kids had thrush before turning 4 months old. My grandmother told me to use a cotton ball or clean white cloth, wet with bit of babies urine from first morning diaper change and wipe on the white patches on tongue and mouth. Cleared in 1-2 weeks.
