I have suffered with a sinus condition for many years. The doctors keep prescribing medicine that did't work very well. One day I saw an add featuring Karen Herbs which was known by another name wich I beleive was Kan Jana. Once I started using this product my sinus seemed to go byby. I only have a sinus problem in the winter so I start taking Kold Kare in Oct., 2 a day for 3 weeks , then 2 every other day until the end of winter or the cold weather ends. This routine I've been doing now for 3 years without any sinus problems at all. This product is godsend.
