According to a tradition from Imam Ja’far-e-Sadiq (a.s.), the meal of Hazrat Ali (a.s.) always consisted of green vegetables. He stated that the heart of Momin is green and has a leaning towards greenness. He also stated that whosoever has eaten 7 chicory leaves (Kasni) during the night, he will be safe from the colic pain and whosoever desires many off-springs should take chicory leaves in large quantities.
Another tradition describes green chicory leaves as a very good vegetable. Not a single leaf of chicory is devoid of a drop of water of heaven and therefore when one eats one should not shake it. It is also stated that chicory leaves (endive) are superior to all vegetables in the same manner as Ahlul Bait (a.s.) are superior to all mankind. chicory leaves when eaten cause birth of male children who are also beautiful. When a person was ill with fever and headache, the Imam (a.s.) asked chicory leaves to be beaten in pulp, spread on paper, and sprinkled with oil of violet (banafsh)a and then applied on the forehead of that person as it will completely cure both the fever and the headache.
