I think NONE: I am not aware of any herbal supplement that consistently causes a positive urine drug tests. Even poppy seeds which used to have false positives for morphine, do not typically find this now, because of the cut off levels.

Perhaps ephedra but: To the best of my knowledge herbal supplements will not cause a false positive on drug tests with the possible exception of ephedra sometimes showing up as methamphetamine, but ephedra has been banned by the fda for safety reasons so herbal supplements no longer contain it. Ingesting poppy seeds may cause one to test positive for opiates, but i don't consider poppy seeds to be an herbal supplement.
