Parsley Piert Drug Interactions, Uses, Safety & More
What is this page for?
First and foremost: how Parsley Piert interacts with medications. The heart of this page is the interaction list — every drug Parsley Piert is known to interact with, and how serious each one is.
But these pages have grown well beyond that into a full monograph — what Parsley Piert is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist.

What Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Where This Data Comes From

Parsley Piert: Uses, Safety & Side Effects
Parsley piert is a small traditional herb used mainly in folk medicine for kidney and bladder problems, especially stones. There is very little modern scientific research to confirm it works for any condition, so claims rest mostly on long-standing traditional use. Talk to your pharmacist or doctor before using it, and never use it to replace proven treatment for kidney stones or urinary problems.

Overview
Parsley piert is a small, low-growing plant despite its name, it is not related to true parsley. It is a member of the rose family and grows as a tiny weed in fields, sandy soils, and dry grassy areas across Europe and parts of North America.
The whole above-ground part of the plant has long been used in traditional herbal medicine, mostly in Britain and Europe. Folk healers used it as a remedy for kidney and bladder problems. Today it is sometimes found as a dried herb for tea, or as a liquid extract or tincture, often marketed as a 'kidney' or urinary tonic.
Uses & effectiveness
People have traditionally used parsley piert for kidney stones, bladder stones, urinary tract discomfort, and fluid retention. It was thought to act as a 'stone-breaking' herb and a mild diuretic (something that increases urine flow).
It is important to be honest: there is very little modern scientific evidence for any of these uses. Most of what is claimed comes from old herbal texts and tradition rather than well-designed human studies. We do not have good clinical trials showing that parsley piert dissolves stones, prevents them, or treats urinary problems.
Because of this, parsley piert should not be relied on to treat kidney stones, infections, or any medical condition. These problems need proper medical evaluation and treatment.
How it works
The way parsley piert might work in the body is not well understood. Like many plants in the rose family, it contains tannins and other plant compounds that may have mild astringent and diuretic-like effects.
Traditionally it was believed to increase urine flow and soothe the urinary tract, which is why it was used for stones and bladder irritation. However, these ideas are based mainly on traditional use and basic plant chemistry, not on solid laboratory or human research. There is no reliable evidence identifying a proven active ingredient or mechanism.
Safety & precautions
Parsley piert has a long history of traditional use and is generally taken in small amounts, but it has not been carefully studied for safety in modern research. This means unexpected effects cannot be ruled out.
People with kidney disease, a history of kidney stones, or heart or blood pressure conditions should be especially careful, since herbs that affect urine flow may not be appropriate for them. Always check with your pharmacist or doctor first.
Pregnancy and breastfeeding: There is not enough information to consider parsley piert safe. To be cautious, it should be avoided during pregnancy and while breastfeeding.
Do not use parsley piert as a substitute for medical care. If you have signs of a kidney stone or urinary infection such as severe pain, fever, blood in the urine, or trouble urinating, seek medical attention.
Side effects
Because parsley piert is poorly studied, its full side effect profile is not well known. As with many herbs, possible effects could include mild stomach upset or an allergic reaction in sensitive people.
Herbs that increase urine flow may cause more frequent urination or, in some cases, changes in fluid and salt balance if used heavily. Stop using it and seek care if you notice a rash, swelling, trouble breathing, or any other concerning symptoms.
Dosing
There is no established, standardized dose of parsley piert. Traditional use involved making a tea from the dried herb or taking a liquid extract, but reliable dosing information from research is lacking.
If you choose to use a product, follow the directions on the label and do not exceed them. Because quality and strength can vary between products, it is best to speak with a pharmacist or doctor before starting, especially if you have a health condition or take other medicines.
