Clinical verdict
Thunder God Vine (triptolide) is a genuinely potent immunosuppressant studied for RA — but with DEVASTATING side effects: male and female INFERTILITY (nearly 100% at therapeutic doses), hepatotoxicity, nephrotoxicity, bone marrow suppression, GI hemorrhage. Therapeutic window is razor-thin. It works for RA but the toxicity profile is worse than methotrexate. Causes complete azoospermia in most men [1].
