Colloidal silver was used before antibiotics were invented and some people still use the former against bacteria and microbes. Colloidal silver is a mixture of silver particles that have been suspended in a liquid.
You can use colloidal silver as a foot wash for athlete’s foot and as a mouth rinse for cold sores.
Exercise caution when ingesting colloidal silver because it may give your skin a permanent blue-grey hue.
Echinacea is used in traditional medicine to treat the common cold since it may help lessen the duration and severity of your cold symptoms.
You can use echinacea petals and leaves to make an infusion. Alternatively, you can make an echinacea decoction from the roots.
An echinacea infusion can be taken as a healing tea or as a supplement.
