In the case I'm going to describe below, it was the very beginning of our work.
If I think detoxes are needed, I *always* start with a steroid detox [of different length and depth] if the child has had steroids [in utero even, as prematurely born children often have], or either parent had a lot of steroids. I find this can really open up cases so that children can heal well.
I also regret whenever I haven't detoxed steroid as I see stronger aggravations and fewer gains with subsequent homeopathic detoxes.
I'll also do this when the child has been largely unresponsive to classically prescribed homeopathic remedies.
Another remedy I use in preparation for children who have *no* response to well chosen homeopathic remedies is thuja. This can clear a case so that the child can start to respond. I had one 19 year old autistic patient who had a life history of non-response. He responded to thuja.
Here's a lovely testimonial of a 9 year old boy with autism, describing his gains from a homeopathic steroid detox & homeopathic opium.
I'll let his mother tell the story as she tells it so joyously, pointing out that her son gained what we often take for granted in our neuro-typical children. :-D
