Hi, I want to include kalonji seeds / oil in my regular diet for two reasons: 1) To improve body immunity (as I often fall ill due to cold / cough arising out of allergy or otherwise) 2) To cure psoriasis (few white spots on my legs, hair thinning & whiteness & hair loss) 3) Improve digestion For the above, I am wondering which one would be more beneficial and effective: Kalonji seeds or Kalonji oil? How should it be taken?
