Parsley acts as a diuretic primarily through its volatile oil compounds, specifically apiol and myristicin. These constituents irritate the kidney tissues slightly, increasing blood flow and glomerular filtration rate to promote urine production. Additionally, the herb's high potassium content helps maintain electrolyte balance while fluid is excreted. This mechanism supports its traditional use for urinary tract support and reducing water retention (Evidence Level: C/Traditional).
Does parsley interact with blood thinners like Warfarin?
Yes, parsley can interact with anticoagulants like Warfarin. Parsley contains significant amounts of vitamin K, which plays a key role in blood clotting. Consuming large amounts of parsley, particularly therapeutic doses used in extracts or teas, can antagonize the effects of blood-thinning medications, potentially reducing their efficacy. Patients on anticoagulants should maintain consistent vitamin K intake and consult a healthcare provider before using medicinal parsley (Evidence Level: C).
Is it safe to drink parsley tea during pregnancy?
No, medicinal doses of parsley are considered unsafe during pregnancy. The volatile oils, specifically apiol, found in parsley can stimulate uterine contractions, potentially leading to miscarriage or premature labor. While small amounts used as a food garnish are generally considered safe, pregnant women should avoid therapeutic doses such as concentrated parsley tea or extracts. Always consult a healthcare professional before using herbal remedies while pregnant (Evidence Level: C/Traditional).
What is the recommended dosage for dried parsley herb?
The standard adult dosage for dried parsley herb is 2 to 4 grams, or approximately 6 grams of fresh herb, prepared as a tea taken three times daily. To prepare, steep the herb in boiling water for 5 to 10 minutes to extract the active compounds. Dosage may vary based on the specific condition being treated, so it is best to follow product label instructions or consult a qualified medical herbalist (Evidence Level: C/Traditional).
Can taking parsley cause kidney stones?
Yes, excessive consumption of parsley may contribute to the formation of kidney stones in susceptible individuals. Parsley contains oxalates, which can bind with calcium in the urine to form calcium oxalate stones. People with a history of kidney stones, kidney disease, or oxalate sensitivity should avoid high therapeutic doses of parsley. Additionally, handling the plant may cause photosensitivity in some individuals due to furanocoumarins (Evidence Level: C/Traditional).

Résumé
Parsley (Petroselinum crispum) is a Mediterranean culinary herb used in traditional medicine for its antioxidant, diuretic, and anti-inflammatory properties [PMID:39735703, PMID:24374449].
Contexte
Parsley (Petroselinum crispum) is an important culinary herb originating from the Mediterranean region, now cultivated globally for use in the food, perfume, and cosmetic industries [PMID:24374449].
Usages traditionnels
Traditional and folklore uses include treatment of amenorrhea, dysmenorrhea, hypertension, cardiac disease, urinary disease, otitis, sniffles, diabetes, various dermal diseases, and gastrointestinal disorders [PMID:24660617]. It has also been used as a carminative, gastro tonic, diuretic, and urinary tract antiseptic [PMID:24660617]. Warm compresses or poultices have been used for breast engorgement and mastalgia [PMID:30000940].
Composés actifs
Active constituents include volatile oils (apiol, myristicin, beta-phellandrene), flavonoids (apigenin, apiin, 6"-Acetylapiin), phenolic acids (p-coumaric acid, caffeic, chlorogenic, and ferulic acids), coumarins (bergapten, imperatori), carotenoids, ascorbic acid (vitamin C), and tocopherol [PMID:30000940, PMID:24374449, PMID:35651051, PMID:34980400, PMID:24660617].
Mécanisme d'action
Parsley exerts antioxidant, anti-inflammatory, and nephroprotective effects through its bioactive compounds, including flavonoids and phenolic acids [PMID:39735703]. It has demonstrated the ability to reduce oxidative stress and inflammatory responses in human keratinocytes [PMID:41020006] and inhibit lipid and cholesterol oxidation [PMID:35651051, PMID:34980400].
Preuves cliniques
Preuve DDermatitis
Application of parsley extract ointment led to a significant decrease in redness, thickness, and scaling [PMID:38338356].
Preuve DMuscle Cramps
A 15.02% reduction in muscle cramps was observed in a subgroup consuming parsley juice [PMID:38338356].
Preuve DUrolithiasis
In rat models, parsley treatment resulted in kidneys that were mostly calculi-free with significantly lower calcium oxalate crystals in urine and histological sections [PMID:29181438].
Preuve CRenal Health
Animal studies showed reductions in oxidative stress and enhanced renal function; limited human studies revealed modest improvements in urinary parameters [PMID:39735703].
Preuve DThrombosis
In rats, intravenous administration reduced venous thrombus formation by 98.2% and oral administration impaired it by 76.2% [PMID:34012875].
Preuve DHepatotoxicity
Sécurité et effets indésirables
Parsley is generally recognized as safe (GRAS) as a food by the U.S. FDA [PMID:30000940]. Adverse reactions are primarily allergic, including cross-reactions to other members of the Apiaceae family [PMID:30000940]. One study of 937 participants found high tolerability, with 96.26% experiencing no adverse effects [PMID:38338356].
Grossesse et allaitement
Some mothers in Türkiye reportedly use parsley to increase milk supply, while oral capsules containing sage and parsley are claimed to decrease milk flow, though no scientifically valid clinical trials support this [PMID:30000940]. No data exist on the excretion of parsley components into breastmilk or safety for nursing mothers and infants [PMID:30000940].
Synthèse des preuves
The current evidence is primarily based on in vitro studies, animal models (rats, mice, yeast), and review articles. There is a lack of high-quality human clinical trials (RCTs), resulting in a low overall strength of clinical evidence.
