I had an aunt who was part Indian and she always heated pineapple juice for whatever ailed us when we were little. Pineapple/pineapple juice contains catalase (which is an important enzyme). It is good for stomach problems and it works in neutralizing H202 in your liver (people with vitiligo have a high level of H202 in their liver). So eat more pineapple!!! I am beginning to think that is what is in pseudocatalase cream.
Pineapple juice! All you have to do is gargle with it, and it tastes good.
I usually drink pineapple, as hot as I can stand it at the first sign of a cold. The morning after there are no more symptoms. This is also an amazing remedy for an established sore throat or voice loss due to a cold. I suffered with a raw throat and loss of my voice for 2 weeks, then someone suggested drinking hot pineapple juice... the next morning, I had my voice back and my throat was no longer raw.
