Golden rule-

     When definite improvement sets in, discontinue the administration of the remedy and do not repeat until the patient fails to show further reaction to the dose.

     Continue with the same potency as long as it gives a reaction.

     If the remedy be well chosen do not be in a hurry to change. In cases of apparent failure first try another potency (higher or lower) of the same drug.

     When in doubt as to the advisiability of repeating or changing wait.

     High potencies often cause a preliminary aggravation.

ü  Low potencies- 1x to 12x. Chiefly used in acute conditions & frequent doses.

ü  Medium potencies- 12 to 30, useful at the beginning of either acute or chronic cases and especially when deep, organic changes are suspected.

ü  High potencies- 200 up, mostly used in chronic conditions and in infrequent doses.

N.B.: Many drugs appear to be inert between 3x and 8x.
