Oh yes, topically, I've read some links that give 28 benefits of CO. Althou, over the years of CO, it's been taken internally for constipation....I do not take it internally as my dosing thru the day of magnesium keeps everything working smoothly for me...mag is so critical for so much. Just the other day, a health guru sent thru a note that 80% are deficient in the U.S. so some experts say, but he said it's more like 99%. Thanks..
