How Baba's Udhi cured many diseases?

There were number of instances where the efficacy of Udhi has been highlighted in Sai Satcharitra. A old man was suffering from kidney stones and the Doctors advised him surgery. As he was very old and keeping indifferent health, he could not convince himself to undergo the surgery. However, the inamdar of the town who was always keeping stock of Saibaba's Udhi happened to come there. He gave Udhi to the son for administering with water to his father. Accordingly, the Udhi was given and within few moments the stone came out of Urine mysteriously. An Iranian gentleman's daughter was suffering from eplipsy. She used to get fits more often and hence her limbs become underdeveloped and she was weak. She was brought to Saibaba. Baba blessed the girl with Udhi. She used to get frequent fits. After Baba's blessings, she got fits once in 7 hours instead of every hour. In a few days, by applying the Udhi and taking it in, she was cured completely. Saisaran, Sairam.
