Tell me yours and I’ll tell you mine? Old wives tales usually have some science behind them that hasn’t been tested yet. No one is saying they have the magic cure-all.
I make a mixture of turmeric, horseradish, ginger, garlic, habanero, hot onion, and apple cider vinegar. Chop finely or blend and let steep and ferment for as long as you want. Doesn’t go bad. I take shots of it when sick. Actually really good to put in stir fry and stews too.
All of those ingredients have proven health benefits. Doesn’t replace antibiotics or medical treatment but can’t hurt. I’ve noticed it reduces the time I’m sick.
