No healing properties have been attributed to the spring in tales, rather the power to confirm or deny fulfilment of future desires. The spring is related to tales about the Devil as a favourite site for satiating one’s thirst. Other nearby objects: Mazsalaca, Skaņākalns Nature Park.
“From the Skābumbaļļa (Souring Tub) or Rūguma ķērne (Brewing Churn) a clear spring flows out. Right on the site instead of a table there is a millstone. In former times there was also a cup, because one had to drink water before making a wish. If the water was sour – the wish would come true, if not — everything would remain as formerly” (Atis Sloka in Mazsalaca; compiled by I. Ruberte. Valmiera County Tales (Valmieras novada teikas).1999) “In ancient times in the Devil’s Cave of the Skaņākalns Hill of Mazsalaca the Devil dwelled, but this was not appreciated by local priests and they wanted to expel him from the cave at all costs. But this could not be easily done. When the priest said the Lord’s Prayer at the entrance to the cave, the Devil prayed along and the prayer’s words did not help. Finally, the priest decided to say the Lord’s Prayer from the other side round. The Devil could not do the same and fled away. When fleeing to Salaca, he knocked over his souring tub that is still seen in the cliff as a spring flowing into the Salaca.” (S. Laime, 2009)
