  1. Dear doctor, Does Nagkesar churna help in improving fertility among women? for example in improving egg quality?

    • It is used as ingredient in a few Ayurvedic medicines used in restoring hormone balance, such as Puga Khanda, Kalyanaka Ghrita, M2 Tone etc. Hence, it has an indirect role in improving fertility. Its exact mode of action is still to be explored.
