I bought this product for a friend that had suffered a heart attack and lost circulation to her legs,there is nothing else that modern medicine can do for her so we thought that we would try these and it appears that this product is helping the blood flow to the legs--any thing that helps is great,she has had numerous types of surgery and this is a new direction that appears to be helping

I use this product in my children's room to keep it fresh. My car has been smelling damp and stale after many trips to the beach this spring! I purchased this item to keep in my SUV and reduce the smell in the car. One tip of advice would be to not puncture the seal inside. I started to open it and then realized I was not supposed to break that seal, just toss the jug in your car or home and its ready to go!
