I would like to know the answer to goodsamaritan also. My 7-mo daughter is suffering from eczema and she is fed 85% breastmeal, the other 15% is the broth, mixed vegetable broth with beef broth based on Weston Price formula. I don't know for sure if it is right for her, but at least at 7 month, she should be eat some solid food. We delay the solid foods because I think she may have leaky gut syndrome, and more foods will make her digestive system more irritable. I rather go with the Weston Price formula then the fake milk and some Genetically-Modified ingredients.
Can the nursing mom take the items that you mentioned above, like yerba mate, watercress or nettle leaf with forskohlii or zizyphus, etc. Nursing mom does not have eczema or psoriasis. But if by taking these things that will help heal the baby, the mom is willing to do so.
