Yes, you can use potpourri in a bath, but it's essential to choose the right kind for this purpose. Select potpourri with all-natural, skin-safe ingredients like dried rose petals, lavender, or chamomile flowers that have no added chemicals or fragrances. The natural oils released from the dried flowers can create a soothing and fragrant bath experience. Fill a muslin bag or a reusable tea infuser with the potpourri and let it float in the warm water to infuse the bath with its scent and benefits.
