I appear to be allergic to penicillin.
Lately I’ve used oil of oregano for things like oncoming colds and what seemed to be a gum or tooth issue. Passion Flower and Valerian for sleep, Oscillococcinum for onset of colds/flu. All work pretty well, for me.
My brother recently found the Boiron Calendula cream as good as the pharmaceutical stuff, for his dry/itchy skin.
Some of the natural stuff works, and of course it is always going to be individual. But if TPTB never put the effort into studying something, they can always say “There is no proof...” - and that goes down as if they had said “Doesn’t work”.
(Having said all of that, sound nutrition and a temperate life in all respects probably represent the best way to avoid health issues.)
Oil of Oregano can kill off any bacteria. Genuine Manuka honey as well.
Cinnamon good for sugar diabetes, helps lower blood sugar.
Cayenne mixed with warm water - for sore throat (gargle), flu/cold symptoms.
Apple Cider vinegar 2T to 8 oz water good for cholesterol (so I’ve been told.
Muscle cramps? - suffer from leg cramps: ingesting a tablespoon of regular yellow mustard helps these to subside in a matter of minutes in most instances.
