Some of the tablets may not dissolve readily so we first crush them in the front teeth and then place them under the tongue for a few minutes before swallowing them. If they are drops then swallow them after holding them under the tongue for a moment or so. If you experience your homeopathic drops tasting or feeling hot in the mouth this is because they are stabilized with alcohol but never to any extent that it would harm you. If you are carrying your remedies with you on an airplane never put them through x-ray machines. Never leave your remedies by microwave ovens, extreme heat or sunlight.
Most herbs act the same way.
All natural things are heat sensitive as well as light sensitive thus using a glass amber colored bottle for your remedies are preferred. Homeopathic medicines are based on the theory of Energy Medicine and once tampered with the electromagnetic energy could be altered or dismissed entirely. Therefore we are careful where we store these types of remedies. Enjoy taking your homeopathic remedies but remember that anything can and will go wrong if you abuse your natural medicine. It is a lifelong and grand privilege to be familiar with Homeopathy.
