Welcome, Steph!

To explore the answer to that try the Solfeggio Frequency Experiment: [Sound and Salt]

Each frequency affects everyone differently - like a mantra. How do you know which is the correct one for you, or even if it is harmful or not? It goes, almost without saying, that your remedy is chosen with great care.
It is possible to prepare a homeopathic remedy using a Radionic device, which uses a modulated electrical signal (like a music synthesiser) to transmit a resonance pattern to the remedy base (sac lac).
The remedy resonates with some part of our body or mind, according to its natural affinity, just as the different Solfeggio Waves did in the salt experiment. In H'pathy the specific effect expected of a remedy comes not only from the frequency but also from the dilution. To pepare a sound remedy in the tradional way the sound would have to transmitted to water (refs: Masaru Emoto & Jacques Benveniste).
The remedy is detected by our sense of taste or smell. How can smell affect our mind? Think of the smell of strong coffee. It has some effect on our mood. Speeds us up! In Homeopathic potency "Coffea" infiltrates the coffee user's state and neutralises it. His (her) mind is sensitive to it.
Staying with the mantra analogy, Homeopathy, like meditation, helps us unravel the complexes deep in our mind ... the sensitivities of the plants can correspond to our own, and are often used to treat anxiety states.

Similarly the atomic and molecular structures of the mineral kingdom can correspond with our own developmental stage. For example, Natrum Muriaticum (salt) is a dilution of ions with a strong affinity ... is it mere coincidence that the Nat-m patient suffers long lasting grief from separation, (especially from Mother)? As you go across the periodic table a series of correspondences, between elements and remedy states, from family to society, becomes apparent.

As you progress down the periods to the heavier elements the issues of the patient progress towards the states self-actualisation outlined in Maslows "Towards a Psychology of Being", culminating with the search for autonomy in the Lanthanide series.
