Homeopathic medicines may be prescribed in several different strengths, or potencies as they are called. The lower potencies have been subjected to less dilution and succussion than the higher ones and are not, broadly speaking, as powerful and long-lasting in their effects. It is the low potencies such as the sixth (e.g. Arnica 6) which are to be found on sale in many homeopathic pharmacies. High-potency medicines are usually prescribed by experienced qualified homeopathic doctors. Homeopathic medicines can be prescribed in different ways. However, homeopathic medicines sold as a combination of OTC product is not the right way of practicing homeopathy. When it is likely that the homeopath and patient will wait for a period of weeks to see the patient's response. A medicine can also be given in a lower potency, singly or repeated daily or more frequently. The homeopath will choose the method to suit the patient and the nature of the illness. For instance, a person who has been ill for a long time and whose body has been physically damaged may need repeated doses of a remedy to stimulate the recuperative powers, whereas a young and basically healthy person may respond very quickly to a single high-potency remedy. Individual patients also respond better to some methods than others; understanding this is part of the skill of the homeopath and explains why attempts to prescribe for oneself may prove ineffective.
