Lisa asked about making remedies go further and rumours she had heard. If you have a single pill left in a vial you can avoid buying a new vial and make it go further.

I have seen this done but am not sure it is an ideal solution for several reasons.
Firstly if you are relying on a single dose of the homeopathically chosen medicine to do the job you want to be sure of your medicines (see stanza 264).
Secondly why do it in the first place as remedies are not that expensive and it only postpones the inevitable.
Thirdly if you buy in medicting potencies to begin with the situation does not arise.

If you must do this for whatever reason you simply fill the vial with a 25% alcohol solution. You then give anything from a few drops to a teaspoon as a dose. The remedy is not being raised in a regular potency step as such. But being in liquid and having to be shaken would alter its potency in some degree.

Incidentally 'plussing' is a way of reducing the size of dose where it is altogether too large (fn134 to stanza 248).
