Is the statement of Sufyan al-Thawri, "Upon you are the roots of sincerity, the leaves of patience, and the juice of humility... your heart's illness will be cured by the permission of Allah," authentic?

This statement attributed to Sufyan al-Thawri has not been found in the references we have consulted. Al-Amili mentioned a similar statement and attributed it to a physician in the Maghreb, who described a spiritual remedy that included elements such as poverty, patience, humility, certainty, awe, sorrow, contemplation, contentment, reliance [on God], truthfulness, seeking forgiveness, and piety, along with abstaining from greed and covetousness. Some preachers attribute this statement to Sufyan al-Thawri as a cure for diseases of the heart and remoteness from God.
