Darbha (Desmostachya bipinnata)
Brahmins always keep Darbha grass in their houses and it is used for purification in all kinds of ceremonies. It grows to a height of about two feet and is thinly pointed at the top. This grass is usually found in damp marshy and low-lying areas.
You will receive 6 packs (or boxes) of incense. Each box will contain 18 incense cones made of Darbha grass and a metal plate on which you can light and place the incense cone.
