Some of the crud going around is tough to shake. Did you take PLENTY of colloidal silver? Did you nebulize as well as take orally? If you nebulize, use 5 parts CS to 1 part lobelia and 1 part mullein for the best results. Oil of oregano capsules and echinacea would be good adds. If you have a lingering sore throat you can get echinace in tincture/extract form and drizzle it down your throat.
As this passes, it would be a good idea to take a good quality probiotic supplement to make sure that you have a healthy internal flora mix. All of the above is what we have been doing to knock out colds and chest infections this year. And just earlier tonight I felt a stomach bug coming on - cramps and grumbling with a feeling that diarrhea was on the way. Took two big swallows of colloidal silver and all appears well now.
