The seedlings/propagations can be planted and then, after the fruit has fully matured (150-180 days), the roots are harvested and washed. The roots are harvested by gently pulling the plant out of the ground. Next, the roots are dried and usually powdered, which can then be used medicinally.

Now, the powder can be added to milk and honey, which is traditional in Indian culture, or used in tea.
