I was also diagnosed with Gilberts/high biliruben back in 2016 from some bloodwork I had done. I was going to try to treat my Lyme with herbals and not do antibiotics. But now I am wondering if abx might be better to try to get rid of the high biliruben.
IMO this is not yet enough proof that ABX resolves biliruban / Gilberts to warrant against trying herbs.
Usually people do ABX cause its easy to do (but hard on the body), herbs are complicated for those who have not studied all the options (not just 2-4 pills a day.)
