When the Heart Flower is forced out, the body separates into two objects; one crystal containing the Heart Flower, and one crystal ball which has the suffering person imprisoned inside of it. The person can only return to normal if the Heart Flower is purified, and the crystals are put back together again. So far, only Pretty Cure has been seen purifying a wilting Heart Flower, and when it happens, the Heart Flower will start blooming again despite the owner's past feelings. After a heart flower is returned to its owner and is cleansed, its Heart Seed forms and the Tree of Hearts recovers.
