Artemisia pallens is a small, sweet-smelling herb from southern India. Most people know it as davana. It is grown near Mysore for its scented oil and for temple flowers.
The plant belongs to the daisy family. It is a close relative of wormwood and mugwort. Its main modern use is in perfume, and as a flavour in drinks and sweets.
In Siddha and Ayurvedic folk practice, davana was treated as a warm, aromatic herb. People used it for coughs, upset stomachs and period pain. Healers also laid it on wounds.
Here is the honest verdict. There are no good human trials of davana for any health problem. A few rat and test-tube studies exist, and that is the whole picture.
Long use in tradition is not proof that a herb works. It is also not proof that it is safe. Davana is best thought of as a scent and a flavour, not a treatment.
The essential oil is very strong. A few drops hold the scent of a large bundle of the fresh plant. That strength is the main reason this page asks you to be careful.
No one has shown how davana acts in the human body. There are no published human studies of its effects.
What exists is early lab work. In test tubes, extracts of the plant mop up free radicals, which are unstable molecules linked to cell damage. Whether that matters inside a person is unknown.
In diabetic rats, davana extracts have lowered blood sugar in a few small studies. This has never been tested in people. It should not be read as a blood sugar treatment.
In laboratory dishes, the oil slows the growth of some bacteria and fungi. Many plant oils do this on a dish. It does not follow that the same thing happens in your body.
The calming effect people report from the scent is simple and real enough to name. Pleasant smells can feel relaxing. That is about mood and habit, not a proven drug action.
Some relatives of davana contain thujone, a nerve-active compound found in wormwood. Reports suggest davana oil is low in thujone. Batches vary, so this is not something you can check at home.
Most davana you can buy is the essential oil, sold for perfume or aromatherapy. It is steam distilled from the flowering tops.
Common forms:
- Essential oil, for scent and for diluted skin use - Davana absolute, a thicker, solvent-extracted perfume material - Flavour extracts used by drinks and food makers, in tiny traces - Dried aerial parts, used as a folk tea in parts of India - Fresh flowering stems, sold as temple and garland flowers - Incense, attars and scented blends
Capsules and tinctures of the herb are rare and not standardised. That means two bottles may hold very different amounts of the active parts.
The oil is a scent material first. Food-grade flavour use happens at levels far below anything a person would pour from a bottle.
Davana has a long place in southern Indian life, mostly as a sacred and scented plant. Flowering stems were offered to Shiva in temple worship. Garlands and hair flowers were a common use.
Farmers around Mysore in Karnataka grew it as a cash crop. Steam distillation for export grew through the twentieth century. Perfume houses in Europe and the United States became the main buyers.
Folk and Siddha practice recorded other uses. Writers described it as warming and aromatic. Recorded folk uses included coughs, fevers, poor appetite, gas, period pain and dressing small wounds.
These records tell you what people did. They do not tell you whether it helped. None of this history is a reason to treat yourself with davana today.
Stop using davana and get medical help if you notice any of these:
- Swelling of the lips, tongue or face, or trouble breathing - A rash that spreads, blisters or does not settle after you stop - Shakiness, sweating or confusion, which can mean low blood sugar - A fit or seizure - Vomiting or drowsiness after anyone swallows the oil
If someone swallows the essential oil, call your local poison centre or emergency number straight away. Take the bottle with you.
See your doctor if the symptom you were treating lasts more than a week or two.
In the United States, davana oil is accepted as a food flavouring in small amounts, and it is used the same way in the European Union. It is not approved as a medicine in any major country. Sold as an aromatherapy oil or a herbal product, it is treated as a cosmetic or supplement, not a drug.
