Protection from evil/Purification (the power of medicinal herbs): Originating from the Tango no Sekku (Boys' Day) custom of displaying iris and mugwort for "warding off evil and expelling negative energy," the green color of the felt mat represents protection from evil and a wish for recovery from illness. The felt mat has the meaning of warding off evil. Decorate your May dolls on the felt mat to ward off evil and celebrate the healthy growth of your children.
