Colloidal silver has a long history of use in home remedies and alternative health solutions, but the scientific evidence for its effectiveness is mixed. Individuals who are considering taking colloidal silver as a dietary supplement should balance the claims with the potential risks of ingesting colloidal silver sprays, solutions or beverages. By learning about the potential side effects and talking with a health professional, it is possible to make an informed decision about colloidal silver.
Skin Irritation
One of the minor side effects of colloidal silver according to the National Center for Complementary and Alternative Medicine is skin irritation. When people consume colloidal silver, the silver salts in the solution can build up in the skin tissues at all layers. TCM Health Info notes that colloidal silver may stimulate the production of melanin in the skin, and that areas exposed to the sun will be more affected than other parts of the body.
Kidney Damage
Kidney damage is one of the more severe side effects of colloidal silver, according to the National Center for Complementary and Alternative Medicine. Liquid silver solutions have to be processed through the kidneys, and the silver particles can cause damage to the organs over time. Of all the organs in the body, TCM Health Info notes that colloidal silver tends to concentrate in the adrenal organs.
Neurological Problems
Another serious side effect of colloidal silver is neurological problems. These problems can include seizures.
Argyria
One of the most lasting side effects of colloidal silver is argyria. According to the National Center for Complementary and Alternative Medicine, argyria occurs when a buildup of colloidal silver happens in the body. This leads to a discoloration of the skin, gums and internal organs of the body. The discoloration has a bluish-gray hue. No treatment currently exists that can reverse the condition once it occurs. The levels of colloidal silver needed to produce argyria vary from person to person, and there is no set time or dosing period for colloidal silver before it will cause this effect.
