How does it feel?
Gravel root is extremely hard. When harvested it has to be chopped with an axe to divide the firmly matted roots. It feels strong, like it can break something, such as a stone. It is acrid, heavy and descending.
All around the world the actions of traditional medicines were understood by their immediate sensory impacts. Click on each of gravel root’s key qualities below to learn more:
What can I use it for?
Gravel root has been used for all manner of presentations affecting the urinary tract that are accompanied by pain, infection and inflammation. It causes an increase in urine production and can help flush out waste products. This action means it can also be of benefit in chronic joint pain.
Traditionally often combined with Hydrangea and Parsley piert or Pellitory-of-the-wall for urinary gravel.
It is important to ensure you are obtaining an authenticated source of this plant. There can be hybridization with other species or adulteration and contamination with other related species such as Boneset (Eupatorium perfoliatum).

Into the heart of Gravel Root
Due to its diuretic properties gravel root has been used to good benefit in the urinary system for infections and urinary gravel, hence its common name. It has been used to good effect along with herbal analgesics and anti-inflammatories in cases of prostatitis.
It can be of help in gout and ‘rheumatism’ – the latter, a catch-all term used to describe conditions characterised by pain and stiffness in the muscles, joints or surrounding fibrous tissue. Useful here as it helps the body to rid itself of waste products via the kidneys.
Traditionally gravel root was used in a similar way to its relative Boneset (Eupatorium perfoliatum) for fevers and as a tonic for debility, especially in older people.
The plant was widely used by Native Americans. The Cherokee used the roots as a remedy for the kidneys and for rheumatism. It was also used as a partus preparator (to prepare the womb for labour) and to tone the uterus. The Chippewa used it when with a cold, inhaling the vapours from an infusion of the plant. The Potawatomi people used a poultice of the leaves for burns, and the Navajo used the herb as an antidote for poison.
Adopted by white settlers it was also used for urinary infection, gravel and stones and as a diaphoretic to help break a fever.
Gravel root was considered a valuable remedy for dropsy – a term once used for fluid retention/oedema and stranguary – another old term used for painful spasm in the bladder and urethra with frequent need to urinate, often whilst only passing small amounts of urine.
Also used for blood in the urine, gout and rheumatism, it was said to exert a special influence on chronic renal and cystic issues.
What practitioners say
Genitourinary tract: In urinary tract infections it has been put to good use when combined with demulcents such as corn silk and urinary antiseptics such as thyme or buchu.
Useful in cystitis, urethritis, dysuria (painful urination) and prostatitis, it combines well with pasque flower for such situations.
Musculoskeletal: The diuretic properties of gravel root make it helpful in osteoarthritis and gout, drawing out impurities by increasing the flow of urine.
Liver remedies are often combined to assist the body excrete waste products via the bowel, thus utilising both these routes of elimination.
Did you know?
The common name of Joe-pye weed comes from the name of Joe Pye, a New England medicine man who was said to have halted an epidemic of typhoid fever in colonial Massachusetts with use of the plant. The ashes from burnt roots have been added as a kind of salt to flavour foods.
Contraindicated in children, pregnancy and lactation.
Whilst gravel root can help in reducing the risk of recurrent issues with urinary gravel, kidney stones require conventional medical attention.
Pyrrolizidine alkaloids (PAs) are naturally occurring phytochemicals found in certain plant families. They are produced by the plants as a defence mechanism against being eaten. Some PAs can be carcinogenic, hepatotoxic and mutagenic.
It is possible, but certainly by no means definite, that Gravel root may contain hepatotoxic pyrrolizidine alkaloids.
Adulteration of Gravel root with other family members such as Boneset can be a risk, along with that of the common occurrence of interspecies hybridization, which has the potential to cause an alteration in the plant’s phytochemical profile.
Overall the research is contradictory and contamination issues are a likely possible issue here.
The European Herbal and Traditional Medicines Professional Association (EHTPA) have decided at present to adopt a watch and wait approach on both boneset and gravel root until more formal research is undertaken where identification/DNA bar coding can be used to identify adulteration issues.
Chemotype and hybridisation issues are more complex but the EHTPA are working with specialists on this.
They are liaising with herbal suppliers to see what can be done to ensure contamination and adulteration risks are limited.
Western herbal actions are
There is scant scientific data on the medicinal actions of gravel root.
In vitro anti-inflammatory activity has been demonstrated from an isolated constituent of gravel root known as cistifolin, a benzofuran flavonoid which may contribute to the plants reputation as an anti-rheumatic herb.
