Royal Jelly for Eczema and Dry Skin?

I have a 6 year old boy who has Asthma and allergies to wheat (which gives him eczema), soy and garlic. Also to dairy, but I haven?t seen any negative reactions to dairy.
Someone recommended use a Royal Jelly-based cream to treat his skin. His skin is constantly dry and with eczema patches. His little fingers often have open wounds from the eczema.
My questions are:
Can I have him tested to see if he?s allergic to Royal Jelly? If so, would he benefit from taking Royal Jelly orally? If he would, what form do you recommend?

If your son is allergic to bee stings or any bee products, you should avoid royal jelly. Adverse reactions include eczema, other skin rashes and bronchial constriction. Royal jelly can be used as part of the treatment for your son's eczema if a skin test determines that he is not allergic. In eczema, it is most important first to look to the diet for food sensitivities, commonly dairy products, eggs and oranges. These should be eliminated from your child's diet before trying any other remedies. For more information, please see our website at www.richters.com. Choose "Q&A" from the main menu, then enter "eczema" for the search.
Royal jelly is a rich source of amino acids, a good source of vitamins B complex, and contains trace amounts of vitamins A, C and E, making it nutritionally valuable. Royal jelly is antibiotic, enhances the immune system and supports digestion. I recommend that you use the liquid form rather than capsule.
Thomas Bartram, in "Bartram's Encyclopedia of Herbal Medicine", states that royal jelly is used for healthy skin, hair and nails, and that it is combined with jojoba oil and vitamin E to make a cream for skin protection.
