Finding information on Homeopathy can be difficult if you don't know where to to look. The first go-to is PubMed, a database of medical research papers. Old Homeopathic journals are also great places to read cured cases. This is interesting as practice for professional Homeopaths and Homeopathic students, and can be interesting for anyone interested in learning what kinds of cases Homeopathy can treat. Archive.org has many old journals, such as the Hahnemannian Monthly, and old Homeopathy texts that are great reads if you are interested in history or philosophy.
If you are looking for broader knowledge on homeopathy, such as ethical arguments for and against it, you can look through SSRN. SSRN is similar to PubMed, but includes papers from a more diverse group of disciplines such as law, philosophy, women's studies, politics, marketing, business, etc.
