Karin: My apologies. When replying I mixed up the meanings of "retrovirus" with "rhinovirus". The rhinovirus is implicated in colds. Retroviruses are implicated in HIV and AIDS. I was up late typing that reply and apparently had a brain cramp in my thought processes! In further reading I learned that St. John's wort is used for "flus" and is supposed to help kill the flu beasties of certain types of flu. I'm still intrigued with it and should the occasion arise that I come down with the flu, I'll try it and let you know how it works for me. ***** Llyn Gruber <[log in to unmask]> ***** **** Whatever you can do, or dream you can, **** ***** begin it--Johann W. von Goethe *****
