Sounds like you and your son have worked hard to achieve the PPP I agree, it may be good just to stay there for a while and see if this holds out.

Biocidin - went to a couple of web pages because I never heard of it. On one site it says it is Grapefruit seed extract and another site Biocidin is a long list of herbal ingredients and I don't see grapefruit mentioned. There is even a Biocidin throat spray.

If you scroll down a little you will come to the story of how grapeseed extract was found to be helpful against fungus and bacteria. http://www.nutriteam.com/gse/gsewhat.html

In the Wiki site it says that there was little antibacterial action of the extract itself. Looks like there was some hot debate as the site is locked. http://en.wikipedia.org/wiki/Grapefruit_seed_extract
