Seb.D. definitely has something to do with the liver. When my liver got sick last year, that is when the seb d. showed up. I personally am going the liver route. I have done one liver flush, will do more. I am taking things to help with liver detoxification and helping the blood filter better through the liver. This is just my opinion, but I am staying on this course for awhile. And, yes, the sun does help me too.
