Elixirs may stand for a period to allow oil particles to coalesce, after which they must be what?

• A. Filtered
• B. Distilled
• C. Refrigerated
• D. Evaporated

Answer: (A)

When oil droplets in an elixir are allowed to coalesce and settle, the next essential step is to remove those settled particles to obtain a clear, uniform liquid. Filtering does this by physically separating the settled oil and any remaining insolubles from the hydroalcoholic solution, yielding a consistent preparation suitable for dosing and storage. Distillation would change the composition by removing or separating components, which is not the goal here. Refrigeration doesn't reliably remove settled oil. Evaporation would alter the solvent balance and concentration, also not desirable. Filtering directly achieves the needed clarification after coalescence.
