Potency and Dosage
In homeopathy, potency is usually used to refer to the degree of dilution that a homeopathic remedy has undergone in its manufacturing process. This is indicated by the number and letter listed after the name of the remedy.
As a general rule, chronic illnesses (i.e. those that you’ve had for a long time) should be treated with low potencies and acute conditions (i.e. those that are relatively new) with high potencies.
Potencies of 30C or lower are considered low-potency remedies, and potencies of 200C or higher are considered high-potency remedies.
There are exceptions, particularly where an accident started off the symptoms and you might give the body a kick start with a high potency dose such as Arnica 200c first and then follow with a lower potency remedy.
If you are not 100% sure which remedy to take, usually a low potency should be taken before a high potency and the patient observed carefully. If symptoms improve but not fully, the same remedy should be taken in a higher potency. If after taking the low potency remedy relief is not felt, or the condition changes, a different remedy should be taken in a low potency.
There are two scales of dilution in common use – the decimal and the centesimal.
Decimal Scale: This potency scale is expressed as ‘D’ or ‘X’. This substance is diluted in a ratio of 1:10.
Centesimal Scale: This is the most common dilution scale used and is expressed as ‘C’. This substance is diluted in a ratio of 1:100.
The letter ‘M’ refers to the 1000th centesimal dilution. Potencies higher than this (e.g. 10M and CM) are also used but generally only by professionals.
