I've never known if there's any veracity to that statement, but I can tell you this. Yesterday, I was sick as a dog with a head cold, and all I wanted throughout the day was either orange juice, or hot apple cider steeped with Oolong tea.
I don't know why the cider/tea combination works so well. Orange juice has vitamin C, so that seems pretty obvious. But I've tried the cider without tea, and the tea without cider, and don't get the same result as I do when I mix the two together. Go figure.
Thankfully, I'm much improved today, but there's a whole season of winter still ahead, and I won't be surprised if I get one more mild case of sniffles before it's over.
So, I'm wondering...what's your preference when you're under the weather: juice, hot tea, or something else? Got any homemade recipes/remedies that do the trick for you?
