Where is a good place to purchase homeopathic remedies?

Multiple sources. Depends on where you are, and how experienced you are in using homeopathy -- some remedies and potencies require a prescription. Health food stores often sell more common remedies. Homeopathic schools/clinics may also have medicinaries that sell some remedies. I buy most of mine from hahnemann labs in california, or helios in the uk. They are reliably prepared, and I trust the results.
