I would say that learning Torah has a quality of being a guaranteed cure for most physical mental and spiritual problems as long as it is not being paid for.

That would go along with what the sages said זכה נעשית לו סם חיים לא זכה נעשית לו סם מוות.
Concerning the words of Torah,if one has merit it becomes for him an elixir of life and if he does merit then it becomes poison.



This idea I saw in the Musar book  of the son of the Rambam, Reb Avraham. מספיק לעובדי השם
