morning, gracie!
but sadly you're mistaken! those colds seem to have found a permanent home with me - they are no longer going around!
I don't get colds very often but when I do, this is a remedy I know works because I've used it as well as other members of my family.
Oil of Oregano, when applied under the tongue has strong antibiotic properties. No more than 2 drops; ask me how I know!
You will smell like a pizza for a bit, but it is so worth it, IMHO.
Large doses of Vit C cannot hurt you, only help, as it is water soluble.
Vit D3 is another very important immune system builder which can fend off infection or shorten its stay! I take 5,000 I.U every day, but if I feel something coming on, I double that to 10,000 I.U. Most folks are deficient in Vit.D3.
