My kids had very, very severe eczema when they were little. We tried EVERYTHING. My son was in the ER many times due to this and hospitalized due to related asthma. The closest thing to working was some natural stuff that we had to apply to bandages and then apply to the affected area (which was his entire body- he even had it on his face and very bad). We didn't sleep nights. It was horrible. Fortunately, they only get a mild case every once in a while now (THANK GOD!!!!)
Where on earth would you get bear fat? Is it alright to kill bears? I would have definitely tried it if I'd had known about it. I would have tried ANYTHING and everything (and did). So... if it works, do pass it on. Maybe it will work for some others. I'm a bit skeptical of something working for every case of eczema as I became close to an expert on the subject

We had both of our children tested for allergies. My daughter was only allergic to cats and dust mites. My son was allergic to everything under the sun including food allergies of milk, eggs, shell fish, and peanuts. The end of his eczema did NOT correlate with knocking these allergens out of his diet. I have been told that it is an immune system issue.
