«بِغَسُولٍ يَرُوقُ الطَّرْفَ، وَيُنَقِّي الْكَفَّ»
A cleansing preparation that pleases the eye and cleans the hand.
Abū Zayd describes a cleansing substance whose alleged benefits extend across several senses and parts of the body. Yarūq means to please or appear attractive; yunaqqī means to cleanse. He also speaks of softened skin and a pleasant mouth. The extravagant list matters as a comic performance, not as a verified medical claim. The same passage also claims stronger gums and stomach; these further heighten the comic exaggeration.
