If we are confident that the remedy is correct, we can go for a higher potency. If we are less certain, we should choose a lower potency to determine its effect. Beginners should only use low and medium potencies. The higher the potency, the longer the period of its effectiveness. The duration of its effectiveness if entirely individual.
Some authors offer orientation charts with the approximate periods of effectiveness.
They vary to a large degree. My personal experience concerning the duration of effectiveness, allows me to be more optimistic than a majority of other authors. Naturally, I only list the longest periods of effectiveness. And in the cases concerned there were no obstructions to the treatment. Of course, often the case is that we prescribe C 200 to a complaint that lasted for many years, that it disappears, and that it is definitely cured.
