My huge family went out to a seafood restaurant. After the meal, my mother offered everyone garlic capsules because, she said, you can never be careful if the food is actually fresh and free of harmful bacteria. Within an hour after the meal and when everyone had gone their separate ways, family members who had refused the garlic caps were calling that they were sick (dizzy, nauseous, throwing up.) My mother rushed over to their houses and gave each of them them 6 garlic capsules. Within 15 minutes they were fine. The ones who refused it, suffered a few more days before they called her and asked if she would come over with the garlic capsules. Now, no one leaves home without a package in their car or their purse. My husband and I take them after every meal we eat at restaurants.
Apple Cider Vinegar also has the same bacterial fighting ability and we add a TBsp to hot tea at restaurants. We carry our own prep bag (a small black bag that fits inside one of my big purses) that contains garlic capsules, homemade salad dressing we grab from the fridge, my special salad seasoning, and a small bottle of ACV.
Garlic gets rid of food poisoning very quickly. Finely mince one medium to large size garlic clove and swallow, chew if you can stand it but it's not necessary. I went to a potluck many years ago and came home with food poisoning. I was extremely ill for a couple days (leaking from both ends) and a friend told me to call his iridologist for some healing tips, which I did and he told me, "no problem take garlic, nothing can live through garlic! " I swallowed some garlic and my stomache jumped for a second and I thought I was going to vomit but didn't and almost immediately started feeling better. I was completely fine within a couple hours.
A few years ago my adult son was hospitalized due to dehydration from vomiting. He had symptoms of food poisoning in my opinion but the doctor disagreed and thought he was passing kidney stones. They never did find any stones in the urine or fecal matter that they collected "and they collected everything that came out of him". When he was released he was still feeling sick so I gave him fresh garlic and it did the trick. He asked me why I hadn't given it to him sooner.
