What kind of reaction did you have with the green tea? I can't do Black-WalnutWormwood , garlic, ginger because it all put me into porphyria due to its all high in sulfur it's a big no no for porphyria it can trigger attacks I just recently learned all of this after experiencing am attack it was really bad and I never want to experience that ever again I thought I was going to die it layede up in bed for 3 days straight. Should have went to the hospital but I didn't. Yes I know it's the bergamot I was researching it already. All early grey tea contains it bergamot some may have more than others though.
