All homeopathic remedies are diluted to be basically water and whatever the base of the pellets are (generally some kind of sugar). That's pretty much how homeopathy works, and one reason it's safe for pregnancy. I can tell you without a doubt that the remedy worked and decreased my symptoms for hours when I took it.
Beyond that, I drank garlic/lemon/honey tea and took CLO and vitamin C. Also had home-made bone-broth chicken noodle soup, which was delicious What I had was pretty mild, but if it was a cold it was a very strange cold. My mw suspects swine flu, but I didn't get tested - honestly only the one day I was feeling really bad would I have considered not going to work back when I was working (except now because of the media hype, I might have thought twice)
