Fill the glass bowl with about 1 quart of vinegar.

Cut large pieces of the brown paper and fold them over several times into strips. Each strip should be about 5 inches wide and 15 inches long.

Place each strip in the bowl of vinegar one at a time.

Remove the strip from the vinegar when soaked through and gently wring it out.

Wind the strip tightly around the affected area. Continue with additional strips until the entire bruised or sprained area is covered. The coolness of the vinegar compress should feel comforting and not painful in any way.

Cover snugly with nontoxic food wrap to keep in place if desired.
