Is there a cure for ulcerative colitis that is not healed by modern medicine, in the Quran or the Prophetic Sunnah?

Firstly: Allah has sent down a cure for every disease, except old age. It is permissible to visit a trusted doctor, for his statement that a disease is incurable is based on his knowledge, and the cure might be known to others, or it might not yet have been discovered.

Secondly: It is permissible to combine visiting a doctor with lawful remedies, which are: 1. Healing with the Quran, lawful ruqyah, supplication, remembrance (dhikr), and humbling oneself before Allah; for the Quran is a cure for both apparent and hidden diseases. 2. Healing through diet and moderation in eating and drinking, and avoiding harmful foods, because most physical ailments are caused by eating food on top of food, and consuming more than the body needs. 3. Healing with what has been mentioned in the Sunnah that benefits this type of ailment, such as honey, black seed, Zamzam water, and talbinah.
