I hope everyone had a great Yom Tov,
Someone came to me last week and asked me to write yud kay vov kay of sheim hashem 7 times on seven small pieces of klaf (vertically). When I asked him why, he told me that he has a growth in his throat and a Rabbi / Mekubel in Israel had said to put the 7 pieces of klaf in 7 cups of water so that the ink should mix with the water. He should drink one cup of water each day for a week.
Two questions on this:
1) Would it be a question of mechikas hashem to do this? Or is the fact that it is written vertically remove this chshash.
2) Is it safe to drink water that has ink and klaf soaking in it?
