A very few words will suffice upon this head. All that has already been written about the care necessary to avoid all exposure of the medicinal substances to damp, dust, strong smells, bright light, etc, during their preparation, applies equally to the preparations themselves after they are completed. All strong tinctures should be kept in a place entirely separate from, the attenuations, and should be preserved in well-stoppered glass bottles, and kept constantly in the dark in a dry, cool place. The attenuations should also be preserved in stoppered bottles in boxes or drawers; and it is a good plan to appropriate a separate box or drawer to each medicine.
It is not necessary to keep the whole series of attenuations, as many of them are very seldom prescribed. The following should, however, be always on hand - viz., all below 7x then 5, 6, 9, 12, 18, 24, 30.
