This worked for my ear infection. Over a period of 5 months, I had antibiotics, silver colloidal, then this. It is lovely. My inner ear did look a bit brown, though I left it 'messy' to show the Dr. for inspection. The Dr. was delighted that finally the infection was gone. Thank you. Yes, I do have a low immune system and anything natural is best for me. Well worth the discomfort of putting up with ear drops. Next time I will know what to reach for first.
