Hope you both are feeling better by now.
I take echinacea and I have not had a cold or the flu in well over 5 years, I'm not kidding.
I use to get severe sinus infections, I no longer get them. It's been over 5 years.
My husband also takes echinacea and he does not get sick. I swear by it. It will boast your immune system that is constantly being attack by germs, our environment and foods we eat.
Also, drinking plenty of water helps keep our bodies in balance.
