(3) Echinaecea, present in so many teas & supplements can be harmful for anyone with an autoimmune disease, causing flares. [source JAMA https://www.hopkinsmedicine.org/gim/_pdf/consult/herbal_meds.pdf] -- this paper discusses lots of other herbs too!

(but you probably don't need this as a supplement) [source, Mayo Clinic https://www.mayoclinic.org/drugs-supplements-l-arginine/art-20364681]
