The weather constantly flips back and forth from fall weather to a taste of late summer..meaning there are days when the temps are in the low 80s and the next day is cold and foggy. I noticed there are some people with the sniffles recently and today I woke up with a slight feeling of the onset of a cold. As you know, I am not a fan of traditional over-the-counter meds but a friend gave me this when I was fighting cancer and I still take it when I feel a slight scratchiness in my throat.
It works for me and doesn't have the lousey side effects of other name brands.
And of course, eat lots of in season fruits and veggies to keep your immune system up to par.
