"Indeed the best of what you treat is As-Sa'ut, Al-Ladud, cupping and laxatives.' So when the Messenger of Allah (S.A.W) was suffering his companions treated him with Al-Ladud, and when they were finished he said: 'Treat them with Al-Ladud.' So all of them except Al-Abbas were treated with Al-Ladud."(Daif)
Jami` at-Tirmidhi Book 28, Hadith 12
← Previous Hadith "We use it as a treatment." So the Messenger of Allah (S.A.W) said: "It is certainly not a treatment, rather, it is a disease."

Another chain reports a similar narration.

Jami` at-Tirmidhi Book 28, Hadith 11 Next Hadith → "Indeed the best of what you treat is As-Sa'ut, Al-Ladud, cupping and laxatives.' And the best of what you use for Kuhl is Ithmid, for it clears the vision and grows the hair (eye-lashes)." And he said:" The Messenger of Allah (s.a.w) had a Kuhl holder with which he would apply Kuhl before sleeping three in each eye."
