Fill the muslin bag 1/2 with lavender flowers and 1/2 with chamomile flowers, then tie a tight knot.
Place the bag into the tub, and fill with hot water to steep the tea.
Let the tea bag float in the water. Sprinkle in the salts to add an extra relaxing effect on the muscles.
Place two cucumber slices on your eyes and soak for 20-25 minutes, to fully absorb the benefits of the herbs and salts.
