Are all remedies available in liquid (dilution)?
No. This is due to the nature of the substance that is being made into a remedy. For example, gold (aurum metallicum) is not soluble in water or alcohol until it has been triturated to the 8x potency (4c). At this potency level, it can then be converted to a liquid and then sold at a 10x or a 4c dilution. A remedy has to completely dissolve in liquid to be available in dilution form.
