Herbs for the prince
Sikh tradition remembers that Dara Shukoh recovered from a grave illness with herbs sent by Guru Ji.

As Sikh tradition tells it, Prince Dara Shukoh once fell seriously ill and did not recover until herbs reached him from Sri Guru Har Rai Ji. The prince remembered the kindness. When his fortunes collapsed years later, this old favour is given as one reason he looked for Guru Ji on his flight through the Punjab.
