What is Sweet-scented Goldenrod?

What is sweet-scented goldenrod?

Sweet-scented goldenrod is a yellow-flowered plant of eastern North America. Crush a leaf and it smells of anise. Dried leaves make the old country drink called Blue Mountain tea.

Folk healers and Eclectic doctors used it for gas, stomach upset, colds and fevers. They also used it as a water pill, meaning something that makes you pass more urine. Today it is sold mostly as loose dried leaf and as a tincture (an alcohol extract).

Here is the honest verdict. No human trials have tested this plant for any health use. Long tradition is not proof that it works, and it is not proof that it is safe.

How does Sweet-scented Goldenrod work?

How is it supposed to work?

No one has shown how it works in people. The ideas below come from lab and animal work. Much of that work used other goldenrod species, not this one.

Goldenrod extracts have raised urine output in animal studies. Lab work suggests the flavonoids and saponins may act on the kidney and on blood vessels.

Whether this happens at tea strength in a person is simply not known.

In test tubes, goldenrod extracts slow the growth of some bacteria. They also lower some markers of inflammation in cell studies. That is a long way from treating an infection in a person.

The anise-like oil is thought to relax the gut and ease trapped wind. That idea rests on tradition and on general work with aromatic oils. It has not been tested in trials of this plant.

What forms does Sweet-scented Goldenrod come in?

What forms does it come in?

Most often you will find it as dried, loose leaf for tea. Tea bags are also sold, sometimes under the name Blue Mountain tea.

Other forms:

- tincture, an alcohol extract taken in drops - capsules of powdered leaf, which are uncommon - essential oil, sold mainly for scent - fresh leaf, picked by foragers

The essential oil is a very concentrated product. It is not a food, and it should not be swallowed.

Quality varies a lot. Loose herb is often wild-picked, and it may be mixed with other goldenrod species.

Where it comes from:

Where does it come from?

Cherokee and other Native peoples used the leaves as a warm drink and a medicine. Settlers took up the habit. The drink spread through the Appalachians as Blue Mountain tea.

After the Boston Tea Party, colonists drank it in place of imported black tea. Some was even shipped abroad as a novelty.

In the 1800s, Eclectic physicians listed it in their dispensatories. They gave it for wind, stomach cramps, colds and to raise urine flow. Those records describe what they believed at the time.

What does Sweet-scented Goldenrod help with?

• Gas, wind and bloating: This was the most common folk use. Eclectic writers called it a carminative, meaning a herb for trapped wind. No human trial has tested it for this. Aromatic teas can feel soothing, and warmth alone may be part of that. If bloating is new, lasting or painful, that needs a doctor, not a tea.
• Mild stomach upset and nausea: Tradition used the warm tea after meals to settle the stomach. There is no human evidence that it treats nausea. The anise scent may make it pleasant to sip, which is not the same thing. Vomiting that will not stop, or stomach pain with fever, needs medical care.
• Colds, chills and mild fever: Folk use was to drink it hot to bring on a sweat during a cold. No trial supports this. Warm fluids of any kind can ease a dry throat and a blocked nose for a short while. It does not shorten a cold, and it does nothing against flu or COVID.
• Flushing the urinary tract: Goldenrod species have a long name as diuretics, meaning they make you pass more urine. German authorities reviewed goldenrod for flushing the urinary tract. That review covered the goldenrod group, not this species on its own. Animal studies show raised urine output, but human trials of Solidago odora are absent. It is not a treatment for a urinary or kidney infection. Those need proper assessment and often antibiotics.
• Sore throat, as a warm drink or gargle: The tannins in the leaf give an astringent, drying feel in the mouth. Folk users gargled the cooled tea. No human study has tested it for sore throat. Any relief is likely short and comfort-based. A sore throat with high fever, drooling or trouble swallowing is an urgent problem.

Which foods are rich in Sweet-scented Goldenrod?

Sweet-scented goldenrod is not a nutrient found in foods. It is a herb, drunk as a tea or used in small amounts for scent and flavour. There is no dietary need for it.

What are the side effects of Sweet-scented Goldenrod?

• Allergic rash, itching or swelling
• Hay-fever-like symptoms in people sensitive to related plants
• More frequent urination
• Stomach upset or mild nausea
• A dry, puckering feeling in the mouth from tannins
• Skin rash from handling the fresh plant
• Rare severe allergic reaction with trouble breathing

Good to know:

How common and how serious?

Serious harm from the tea is rarely reported. But no safety trial has ever been run, so true rates are unknown.

The two real concerns are allergy and the estragole in the oil. Allergy can be sudden and severe in sensitive people.

Stop at the first sign of rash, swelling or wheezing, and get help.

How much Sweet-scented Goldenrod should you take?

• Recommended daily: How much do labels carry? Packets of dried goldenrod tea usually suggest about 1 to 2 grams of leaf per cup. Many labels allow a few cups a day. That is what the package says, not advice for you. The essential oil carries no safe amount to swallow. Its estragole content is the reason, and that is why none is given here. Check with a pharmacist or doctor before you start, especially if you take daily medicine.
• Best time of day: When do people drink it? Timing does not matter much. Many people avoid it late in the evening, because it may send you to the toilet at night. For a cold, it was drunk hot at any time of day.
• With or without food: With or without food? Either works. Tradition favoured a cup after meals, for wind and fullness. If it upsets your stomach, take it with food or stop. Drink normal amounts of water alongside it.
• Time to effect: How fast would you notice anything? Any effect people report is quick, within an hour or so, and mild. Extra trips to the toilet are the most noticeable change. It may also do nothing at all. No trial has measured this in people, so there is no honest timeline to give.
• How long to take it: How long do people use it? Traditional use was short. People drank it for a few days during a cold or after a heavy meal. No study has tested long-term use, so safe length is unknown. Because of the estragole in the oil, daily use for months is not a sensible plan. If your symptoms last more than a week, stop and get checked.
