Andrographis is apparently useful for microglial inflammation. I have recently added it to my armamentarium. http://jpet.aspetjournals.org/content/308/3/975.full

"Therefore, inhibition of only one or two factors by selective inhibitors may not be sufficient to halt the degenerative process. Thus, searching for drugs that have widespectrum anti-inflammatory effects and that remain effective after the initiation of the inflammatory process may be most promising. In this study, we reported that ANDRO exhibited a neuroprotective effect in both pretreatment and post-treatment schemes and was effective in attenuating LPS-induced production of several proinflammatory factors, including superoxide, TNF-α, NO, and PGE2."
