    I have purchased Gokul pitta tea. The ingredients are Liquorice ,Aniseed, Rose Petals, Bishop weed, Cinnamon, Coriander, Ginger.

    There are some ingredients like Bishop weed and Ginger which are pitta increasing. Why are these ingredients added in pitta tea.

      One logical explanation is, they help to correct Pitta. (rather than balancing Pitta). Correction of Pitta means, correcting digestion strength (Agni). Hence the said ingredients.
      But ideally, Pitta tea, by its definition should contain only those ingredients which calm down Pitta.
