Such a mindful little creature this one - caught it with my very 1st kiss - was ill for months, then when thought could go no longer, it went of its own accord. to re-appear with a vengeance years later. Left side of upper lip right up to the nostril. Achieved some success in winning time between bouts with saline mouth and facial washes - until discovered Colloidal Silver in 2000 - things improved mightyly after that. Went for a couple of years before anything came to the surface. Then it came back with too much sunlight - now use a combination - look at this word carefully please - it has hidden depths - combi-nation. Using a host of live cultures every day in a yogurt drink, then bathing/mouth washing with saline, and then taking the Colliodal Silver in a 3 weeks on 3 weeks off rota, we have lift off.  

So, live cultures keep the bio-flora of the mouth happy, washing/rinsing the mouth/face gently helps the creatures that live in our bodies do their job better - next the Colloid, helps to re-build/re-new tissue much faster.  And lastly NO SUGAR - it helps the little beast to grow and multiply. Hope it helps - God speed
