There is a subdomain in homeopathy concerning the use of "cell salts". These are 12 mineral combinations found in the human body. The proponents of cell salts seem to be able to heal almost all illness by re balancing one or more of these salts (and silicea).
If you would like to dive in, I recommened the book by Boericke and Dewey (two masters of homeopathy). It's called: The 12 Tissue Remedies of Shussler.
