I have never seen Black-Walnut associated with a heavy metal detox but why not? Green Hull Black-Walnut is a little miracle waiting to happen.
The Chlorella helps move the heavy metal to the urine stream according to my chelation group. They are dedicated to detoxing their children for serious heavy metal chelation. They have never mentioned Spirulina but Spirulina is good stuff. Now Miso soup might just end up in my protocol if you can tell me what it would do for a heavy metal detox? It reads yummy anyway.
I don't want to add too much stuff though because I want to know what worked and did not. If the Rudenski's Modified Poor Man's Heavy Metal Detox Plan doesn't work for me then I might add some of the additions you mentioned. Cilantro is a powerful chelator though and I know it will move the metal... I just want to move it out of my body...
