You might want to try some of these but hey are not specific for alternative medicine, and some of the information are not for free.

Another thing you might try is, there should be many web sites on 'chinese medicine' however they would be in chinese, yet there are programs available from the internet to translate a web page from one language to another(in your interest - chineses to english)
Sorry... this may not be much help at all, but it is an option you may like to consider
