Our Review: Homeopathy is probably one of the most complete databases available on homeopathic remedies that you can use at home. If not you can add records as you please. Simply search for a keyword like headache and it comes up with a list of homeopathic remedies you can use. In addition, there is a symptoms page where you can search for the usage of a particular herb. This will go well with another Zentrum product "Herbs". Not much documentation is provided but the program itself is pretty much self-explanatory. A little bit buggy but who could complain at this price..
