My mom had reoccurring ear infections for years as an older adult due to swimming. She kept going to the doctor because nothing seemed to be effective; or if it worked, the infection would return within a couple months. I told her about the use of colloidal silver. After being sick of the pain and multiple doctor visits with no success, she let let me put the silver in her ear intermittently, and she took it orally as well. Within a couple days the ear infection was gone and it has not returned since.
