I suppose that MH is right that all calcium and mineral rich herbs help detox, even the bible says that herbs are for medicine.
cilantro, dulse, barley grass juice powder, spirulina
I'm currently following Anthony William aka the Medical Medium and he has a heavy metal detox smoothie, a tasty recipe that he recently had several youtube/instagram videos on explaining his synergistic blend. Basically 2 bananas, a cup of cilantro, a small handful of dulse, 1 tsp of barley grass juice powder, 1 tsp of spirulina, and 1 cup of orange juice. Water or cocunut water can be added to thin it out. basically mix in a high speed blender.
He also had podcasts.
He's also the original celery juice guru. I've juiced more celery juice in the last 6 months than I probably every eaten before in my life. It's believed to be a natural liver/gallbladder cleanser that destroys pathogens if done correctly as he specifies, basically 30 to 60 ounces first thing in the morning 30 minutes after some fresh lemon juice.
