Garlic is a natural immune building food. Though it's not medication by no means, but it does help build the fish's immune system. keeps the fish strong, and since fish love garlic, it's great.
Best treatment for ich for me has always been, temperature rise in aquarium, feed plenty of garlic infused foods and turn off the lights. I've stopped having illness problems.
Clean water is always best, and no matter what you do or what you feed your aquarium with, you'll have a better time with clean water. Otherwise, no matter what you feed, your fish would die sooner than later.
