White genepi is a small alpine wormwood, Artemisia umbelliformis. Its dried flowering tops flavour the mountain liqueur known as genepì. In the Alps it was also brewed as a bitter tea.
The plant grows high up, on rock and scree. It is scarce in the wild and protected in many Alpine areas. Most of what is sold today comes from farms, not from picking.
Most people meet it as a liqueur served after a meal. Dried herb for tea is also sold. Oils and strong extracts exist too, and they are far more potent.
What does the evidence show? There are no good human trials of white genepi for any health use. Long use in a tradition is not proof that a plant works, and it is not proof that it is safe.
Nobody has shown in people how white genepi acts on the body. What follows is a set of ideas, not proven effects.
The herb is very bitter. Bitter plants are thought to prompt saliva and stomach juices, which may be why they were taken after food. This has been studied for bitters as a group, not for this plant.
In lab dishes, the plant's oil slowed the growth of some bacteria and fungi. It also mopped up free radicals in test-tube antioxidant tests. Whether any of that happens inside a person is not known.
The oil holds thujone. In animal and cell work, thujone blocks a calming brain signal called GABA. That is the reason high doses can cause fits, and it is a hazard, not a benefit.
You will most often find it in these forms:
- Genepì liqueur, made in Italy, France and Switzerland. This is the common form. - Dried flowering tops for tea or infusion.
- Herb steeped in spirit at home, a regional custom. - Essential oil and concentrated extracts, mainly for flavour and research.
The liqueur is strong alcohol, often 30 to 40 percent. That matters more for most drinkers than the herb itself. The essential oil is not a food and should not be swallowed.
White genepi has been valued in the Alps for centuries. Shepherds and villagers in the Aosta Valley, Piedmont, Savoy and the Swiss Alps gathered it above the tree line.
It was taken as a warming tea for chills, coughs and fevers. It was also drunk after heavy meals to settle the stomach. Mountain guides carried the liqueur as a pick-me-up.
Distillers began bottling genepì in the 18th and 19th centuries. The name covers several alpine Artemisia species, not only this one. Heavy picking later pushed the wild plant into protection, and farm growing took over.
Stop and get urgent medical help if someone has a fit, collapses, or becomes confused after taking a strong extract or the oil. Repeated vomiting after a large amount also needs urgent care.
See your doctor if you get a rash, swelling of the face or lips, or trouble breathing. Those point to an allergy. Also speak to a doctor about stomach pain or indigestion that keeps coming back, rather than treating it yourself.
In the European Union, drinks made with Artemisia species face legal limits on thujone. Wild picking is restricted or banned in many Alpine regions, so farmed herb is the norm. In the UK and the US it is sold as a flavouring, a herbal tea or a liqueur, and it is not approved as a medicine.
