I actually bought this and gave it to my sister who is battling bronchitis, She love's it!!!
I give it a 5 for effectiveness
You can put on your wrists at night, I'm a side sleeper(sleep with hand under head) helps better than on my back.
Great product!! I use before bed, sleep all night without waking up coughing,no congestion in the morning.
Really enjoying my Kheyleve products! And the prices are so reasonable! Thanks!
