This is a great solution for many problems. There are even kits that you can buy to make your own colloidal silver so you don’t have to buy it yourself. It serves many different purposes, but my daughter-in-law uses it for her sinuses. Every winter she gets a sinus infection due to the dryness in the air.
What she does is use our colloidal silver and puts it in a nasal sprayer. She uses it 2-3 times a day for about 5 days and the infection is gone. She doesn’t use any antibiotics or other type of over the counter medication.
It has gotten to the point she won’t use anything else to get rid of the sinus problem.
