And some information on Elderberries too:
I've seen the proof in my own home as well as at the store with customers coming in regularly for products such as these raving about how well they work. I like the Hot Drink option because I can make a soothing tea to curl up with - or add it to my smoothie in the morning before I rush out the door - super versatile. Plus the kids and hubby didn't mind the tea either - I added a little honey and they drank it down!
Next I'm going to try Host Defense's My Community since the kids were both complaining of scratchy throats again this morning!
Gotta love cold & flu season! I'll let you know what happens :)
