After all, although alchemists were wealthy and lavish with their spending, that did not mean every medicinal ingredient in the world could withstand such waste.
The method of Returning Pills was, in essence, a means developed by alchemists over tens of thousands of years to conserve pill-refining resources in a roundabout way.
