We call Homeopathic remedies, energetic medicine as they are incredibly highly diluted. Therefor it is easy for them to become ‘polluted’ or made inactive by incorrect handling or storing them.
Store your Remedy in a cool, dry and dark place away from strong odours. (I.e. coffee, peppermint, menthol) and direct sunlight.
Keep the Remedy in the packaging it came in, with label intact.
A Homeopathic remedy can be safely stored for a very long time in this way and retain its effectiveness for future use, should that be required.
