Potency indicates how many times the remedy has been diluted and succussed (banged) when it has been made by the pharmacy.
For home prescribing use 6x, 6c or 30c – the same frequency of dose as directed for any of these potencies. These potencies are also the most available and should be effective in the majority of cases.
Higher potencies (ie 200c, 1M, 10M) will need less doses and are only sometimes required in acute prescribing. Usually these potencies will be prescribed by your homeopath and are not generally dispensed by a homeopath or pharmacy for home prescribing, although we do have some 200c potencies in our store.
If you are unsure what to buy, go for the 30c as this is what we call “a good mid-range potency” and should help whether you are managing a cold or an emotional upset.
