In the past, parents and grandparents used magical procedures inherited from their ancestors to cure an ill child. In general, parents were terrified by the prospect that someone might cast a spell on their newborn, so they employed all sorts of precautionary measures to keep evil spirits away from the house.
Some of the most curious measures to prevent evil spirits from harming babies included making smoke, spitting on designated areas, placing a broom by the door, placing a garland of garlic in the window and burying metal objects underneath the threshold of the front door.
If the baby cried a lot, it was quickly established that the child has been suffering from evil-eye spell. In the next step, parents investigated the sources of bewitchment. Convention held that potential evildoers had bushy eyebrows grown together; as a result, suspicion usually has shifted to individuals in the community with such features, as it was believed that people with such physical appearance were capable of performing magical acts. When the parents found out who cursed the child, they went to the offender's house and took some wood scrap – e.g. roof shingles -- from his house and some wood chips from his backyard,then they boiled the junk in water for a while and mixed the solution to the baby's bathwater.
In the past, coal was used extensively to cure cursed children. Coal was employed in different ways. When parents found out that their baby was cursed they put coal in the child's bath water and gave the baby a thorough bath; then, the newborn was wrapped in its father's shirt turned inside out -- this is to make sure that evil spirits won't harm the child anymore; then, the bathwater was poured behind the door.
Occasionally, parents took the baby to a nearby cross-road where the shirt was slashed off from the child, then the baby was taken home and given a bath in a specially prepared bathwater, which included yeast, earth brought from a grave-site, wood chips carved from a wooden cross and pieces of trash from a nearby garbage dump.
In the Northern region of Őrhalom, the Palóc people used the following elaborate procedure to identify the offender who cast an evil spells on their child. They dropped four pieces of coal in a bowl of water; each piece of coal has been given a name: The first one was called man, the second woman, the third boy and the fourth girl. The piece that first sank to the bottom of the bowl indicated the entity that cursed the child.
After the procedure was completed the water was poured into the four corners of the room to protect the child against further evil practices.
