Is it permissible to blend seven Sidr leaves in a blender at home to use them for ruqyah, and is the Sidr plant the same as what is called "nabq" in Egypt?

Washing with sidr water for the treatment of magic has not been established in authentic hadiths. Rather, it was narrated by Wahb ibn Munabbih and transmitted by some scholars, that seven green sidr leaves are to be taken, crushed, mixed with water, and Ayat al-Kursi recited over them. Then, three sips of it are to be drunk, and one should bathe with the rest. This has been found effective in dispelling magic, and there is no harm in using a blender to crush the leaves.
