Power of the minimal dose

Such a globule*,1 placed dry upon the tongue, is one of the smallest doses for a moderate recent case of illness. Here but few nerves are touched by the medicine. A similar globule, crushed with some sugar of milk and dissolved in a good deal of water (§ 247) and stirred well before every administration will produce a far more powerful medicine for the use of several days. Every dose, no matter how minute, touches, on the contrary, many nerves.
*These globules (§ 270) retain their medicinal virtue for many years if protected against sunlight and heat.
