Artemisia pallens Wall, ex DC. is a small, herbaceous, aromatic plant with an exquisite aroma. It is grown in southern parts of India particularly in the states of Karnataka, Tamil Nadu and Andhra Pradesh. It is apparently native to this area in south India. However, it is not found growing wild in this area probably because its seeds are very small and the seedlings are very delicate and need to be nurtured with extreme care until they are at least one month old. A. pallens is locally known as davana and its essential oil is known as davana oil all over the world. A. pallens is, therefore, referred to as davana in this chapter.
