Child suffering serious digestive problems. Help!

Hi everyone, I have a nine year old who is always extremely bloated. She looks like she is hiding a balloon under her clothes. She never have complete elimination and sometimes her appetite is very low. She throws up very easily and she has eczema, which is controlled by a wonderful homeopathic remedy. It breaks my heart. Her pediatrician thinks it is normal. I took her to a homeopath who said that her digestive system is extremely sluggish and that her gallbladder hardly functions. He also stated that she has parasites. Since she is just a child he is not suggesting any hard core cleanses; instead she is taking some herbal oil which is ineffective to me. I have been looking for months for a safe colon, liver and parasite cleanse for her but each time I feel comfortable about a recipe, I read complaints about it. I am completely at a loss and I am tired of searching the web and reading books. My child needs help as soon as possible but these doctors do not seem to be of much use. I would like to note that she never eats junk food and that I try to cook healthy food and I cook everything from scratch. I am trying to encourage her to take more water and I hope for the best. I heard about the P&B shake; anyone knows the exact recipe? Anyone has a reliable safe recipe? Thanks. Tweet
