Hi Katharine
There are some classical homeopaths in France but they are called Unicistes I believe. One very well known and respected classical homeoapth is Dr Edouard Broussalian. You could do a google search and possibly find out more about him and maybe an email address. He should be able to help you find a classical homeopath in Paris. This french site may be of some help

I am happy to hear that you are not self treating.
Good luck
