Track Roseroot with reminders and record whether it helped, in the app.
Roseroot is a hardy mountain plant from the cold parts of Europe, Asia and North America. The root and rootstock are dried and used as a herbal supplement. Cut root smells faintly of roses, which gives the plant its name.
It is sold as an "adaptogen". That word is used for herbs said to help you cope with stress. Most products aim at tiredness, low mood and poor focus.
The honest verdict on evidence: human trials are small, short and mixed, so nothing here is proven. Long traditional use is not proof that it works. It is not proof that it is safe either.
Nobody has shown how roseroot works in people.
In animal and cell studies, its marker compounds seem to shift stress hormones. Rodent work points to changes in cortisol, a stress hormone. Whether that happens in people at label amounts is not known.
In lab tests, extracts also act on serotonin and dopamine. These are two brain messengers linked to mood and drive. This is used to explain mood claims, but it stays an idea, not a proven path.
A few small human trials measured stress hormones or reaction times. Results were mixed and the groups were small.
You will mostly meet roseroot as a capsule or tablet of dried root extract.
Other forms are sold as well. Dried root is brewed as a tea. Alcohol tinctures and loose root powder are also on sale.
Extracts are the form used in most trials. Labels often name a named extract or the 3:1 rosavin to salidroside ratio. Tea made at home has an unknown strength.
Roseroot also turns up in mixed "energy" blends with caffeine or ginseng. Blends make it hard to tell what caused any effect, good or bad.
Roseroot has a long record in the Nordic countries. The root was called rosenrot in Norway and Sweden, burnirót in Iceland and ruusujuuri in Finland.
Old accounts say Viking travellers took it for strength, though that story is hard to check. Linnaeus wrote about its use in 18th century Sweden. Folk use also covered headaches, sore skin and general weakness.
Sami and other northern peoples used the root as food and as a tonic. Russian and Soviet scientists studied it from the 1960s onward. Their work made it popular with athletes and soldiers, but much of it was never published in full.
Stop taking roseroot and speak to a doctor if you feel jittery, restless or unable to sleep for more than a few days.
Also see a doctor if your mood swings, your heartbeat races, or you bruise or bleed more easily than usual.
Get emergency help for swelling of the face, lips or throat, trouble breathing, chest pain or fainting.
If you are using roseroot for low mood and you feel worse, or you have thoughts of harming yourself, seek help the same day.
In the United States roseroot is sold as a dietary supplement. In the UK and the EU it is sold as a food supplement. It is not approved as a medicine for any illness in these places, and wild digging is limited in some Nordic and Alpine areas.
