Detox artificial dyes?

Hey all. I have a daughter severely allergic/sensitive to artificial dyes: she gets hives, aggression, ADHD symptoms, sleep disturbances, worsened eczema, allergic rhinitis, the whole 9 yards. She is a completely different child off of them. Very sweet and confident and attentive and helpful- certainly energetic but not mean at all.

I accidentally gave her a cupcake I thought would be ok 4 days ago and finally figured out why she is behaving MONSTROUSLY🤦‍♀️ Picking off sprinkles is apparently not enough. They have to put dyes in chocolate batter for some reason. Sigh. Poor thing feels very yucky.

Anyways. Do any of you have any tricks to speed up getting this out. It will take 1-2 weeks otherwise. We’ll deal obviously if we have to wait but I thought you guys might know things that help.

Thanks.
