Curly parsley (*Petroselinum crispum*) is a biennial herb used as a seasoning and as a source of medicinal plant material. It contains vitamin C, carotene, B vitamins, mineral salts, and other plant compounds. Herbal reference books have traditionally associated parsley with diuretic effects, digestion, and maintaining eyesight. However, ordinary parsley leaves and concentrated preparations require different approaches.

Parsley is a familiar kitchen herb. People add it to soups and main dishes for flavor and decoration. Traditional herbal practices have also used the roots and mature fruits of the plant. However, medicinal use of parsley has limitations that you should know about in advance.

## What is curly parsley, and how can you recognize it?

Parsley belongs to the carrot family, Apiaceae. It is a biennial plant grown in gardens in many regions.

In the first year, it develops a rosette of leaves and a root. In the second year, flowering stems grow from the root. Small flowers then appear in compound umbels, followed by fruits.

According to botanical reference books, parsley usually grows to a height of 50–100 cm. Some stems can reach one and a half meters. The root is fleshy and spindle-shaped, yellowish on the outside and white inside. It can grow up to 30 cm long.

The leaves are divided and have long stalks. They have a distinctive aroma. When dried, the smell and taste of both the leaves and roots become noticeably weaker. There are leaf and root varieties of parsley. The first is grown mainly for its greens, while the second is grown for its developed root. The curly form has deeply crinkled leaves. Parsley is propagated by seeds. In the wild, it occurs in Southern Europe. In gardens, it is grown for its leaves, roots, and, in some cases, fruits.

Identifying wild plants requires particular care. Parsley can be confused with other members of the Apiaceae family. Reference books describe cases of poisoning caused by hemlock, which was mistaken for parsley or other edible plants. For this reason, unfamiliar greens should never be eaten without reliable identification.

## What beneficial nutrients does this plant contain?

According to herbal reference books, parsley leaves and roots contain vitamin C, carotene, vitamins B1, B2, K, PP, and E, as well as folic acid. Other listed components include potassium, magnesium, and iron salts, pectins, and phytoncides.

Herbal guides pay particular attention to vitamin C. Some descriptions state that parsley greens may contain several times more of it than lemons and oranges. The actual amount of vitamins you get depends on the portion you eat.

Parsley can complement a varied diet. You can add it to meals alongside other vegetables and greens. But the presence of vitamins and minerals does not, by itself, make a plant a treatment for a specific disease.

Older reference books discuss the leaves, roots, and mature fruits separately. The fruits are often called parsley seeds. Essential oil and apiol were also obtained from them. These forms differ from ordinary parsley greens in their concentration of active compounds and require greater caution.

## How can it benefit the blood and overall nutrition?

Parsley contains iron and folic acid. These nutrients take part in normal blood formation. For this reason, parsley can be part of a varied diet that provides the body with essential nutrients.

Books about natural nutrition discuss parsley alongside other green vegetables. It is eaten fresh, added to dishes, and included in combinations of vegetable juices.

However, it is important to distinguish nutritional value from disease treatment. If someone has anemia or a deficiency of certain nutrients, eating greens alone is not enough to identify the cause or determine the appropriate care.

For people with blood disorders, parsley should be considered only as a food, provided it is suitable for them. Medicinal recipes and concentrated juices should be discussed with a doctor beforehand. They may be used only as a complement to prescribed treatment. Never stop medication on your own.

## How does this herb affect the kidneys and bladder?

One of parsley's traditionally described properties is its diuretic effect. According to pharmacological reference books, the plant's essential oil has a pronounced diuretic effect.

Herbal guides mention parsley for conditions involving reduced urine output and certain functional bladder disorders. They also describe water-based decoctions made from the whole plant or individual parts.

However, a diuretic effect does not mean parsley is suitable for every urinary tract condition. Reference books specifically state that medicinal preparations of the plant should not be used for acute inflammatory kidney diseases or acute cystitis.

People with chronic kidney disease also need to be particularly careful. Do not use concentrated preparations on your own or try to change fluid output with herbs.

For kidney and bladder conditions, parsley should be used medicinally only after consulting a doctor and only as a complement to prescribed treatment. Do not stop prescribed medication.

## How can its leaves benefit eyesight and oral health?

Parsley contains carotene, which the body uses to produce vitamin A. Older reference books mention the plant in connection with maintaining eyesight. They also describe its traditional use for chronic gastritis with reduced stomach secretory function.

Another traditional use concerns oral health. An encyclopedia of medicinal plants notes that fresh parsley was used to reduce unpleasant breath. It also describes the plant's effects in the mouth.

These accounts relate to traditional uses of the plant. They do not mean parsley can eliminate every cause of bad breath or help with every eyesight problem.

If your eyesight deteriorates, the cause needs to be investigated. Persistent bad breath also warrants a consultation with a specialist. Parsley can remain part of your regular diet, but it does not replace an examination or prescribed care.

### Can you eat parsley if you have gastritis?

Medicinal plant reference books mention parsley for chronic gastritis with reduced stomach secretory function. This describes a traditional use, not a universal recommendation for everyone with gastritis.

Stomach conditions can differ in their causes and course. Therefore, older recommendations should not automatically be applied to every diagnosis. In an ordinary diet, parsley is used as a seasoning. It is added to soups and main dishes to give them flavor.

Medicinal use of roots, seeds, and concentrated juices requires a separate safety assessment. If you have gastritis, these preparations should be used only as a complement to prescribed treatment and after consulting a doctor. Do not stop or change prescribed medication on your own.

### Is this seasoning suitable for people with diabetes?

A folk recipe using parsley leaves and kefir appears in traditional practice. The leaves are covered with a glass of kefir and consumed on an empty stomach. The recipe suggests using as much parsley as possible.

This is a folk remedy, not an established treatment plan for diabetes. The suggestion to use large amounts of parsley should not be taken as a recommendation to eat unlimited portions. For diabetes, diet and treatment are tailored to the person's condition and the doctor's instructions. Parsley can be used as an ordinary herb if there are no individual contraindications.

Medicinal quantities and folk recipes should be discussed with a doctor. They may be considered only as a complement to prescribed treatment. Never stop diabetes medication on your own.

## What should you consider if you have gout or kidney stones?

With kidney stones, it is important to consider the composition of your diet and the type of stones. Medicinal plant reference books list parsley among vegetables rich in oxalic acid. People with oxaluria are advised to limit such foods.

This does not mean that everyone with kidney disease needs the same restrictions. The diet depends on the nature of the condition and the treating specialist's recommendations. Traditional herbal guides contain parsley recipes for kidney stones. However, the plant's historical use does not prove that such a recipe is suitable for everyone with stones.

The reference books cited here do not establish a specific medicinal regimen for parsley in gout. Therefore, do not take concentrated decoctions or use large amounts of parsley for medicinal purposes on your own.

For gout, kidney stones, and kidney disorders, such preparations should be used only as a complement to prescribed treatment and after consulting a doctor. Do not stop medication.

### What is known about using curly parsley for heart disease?

Older pharmacological reference books describe the use of parsley for certain heart conditions accompanied by fluid retention. Interest in the plant was linked to its diuretic effect and the properties of some essential oil components.

However, these accounts do not justify considering parsley a treatment for heart failure or other heart diseases.

Using diuretic herbs on your own when you have heart disease may be unsafe. Removing fluid affects the body's water and salt balance. In addition, herbal preparations can interact with medications.

For heart conditions, parsley should be used medicinally only as a complement to prescribed treatment and after consulting a doctor. Do not change doses or stop prescribed medication on your own.

## How is it used in food and herbal medicine?

The most common way to consume parsley is to add fresh leaves to food. According to reference books, the greens are used in soups and main dishes. They add flavor and provide vitamins as part of the diet.

The root is also eaten. It has a distinctive but milder aroma and a slightly sweet taste.

Herbal medicine references describe the use of the plant's leaves, roots, and mature fruits. Essential oil and apiol were obtained from the fruits. However, medicinal plant material should not be treated as equivalent to the greens added to a salad or soup.

Seeds require particular caution. According to reference books, they contain the highest concentration of apiol. Prolonged overdose can damage the liver and kidneys.

### How can you use fresh parsley in dishes?

You can add parsley to vegetable dishes and use it as an aromatic seasoning. Books about natural nutrition include recipes combining greens, onions, and vegetables.

For example, green beans can be cooked with chopped sour or underripe apples, minced parsley or onion, a little salt, and oil. Once the beans become tender, you can add a spoonful of coarsely ground wheat flour.

In another recipe, mushrooms are stewed with parsley or onion and then combined with potatoes cooked separately. These are ways to prepare ordinary food. They should not be treated as disease treatment plans.

### What parsley juice combinations are described in natural nutrition books?

Books about juice therapy describe several combinations of vegetable juices with parsley. One mixture contains:

- Carrot juice — 210 ml.
- Celery juice — 120 ml.
- Parsley juice — 60 ml.
- Spinach juice — 90 ml.

Another combination consists of carrot juice — 270 ml, celery juice — 150 ml, and parsley juice — 60 ml.

A further mixture is described using carrot juice — 210 ml, celery juice — 150 ml, chicory juice — 60 ml, and parsley juice — 60 ml.

Another version is made from two carrots, one celery stalk, a quarter of a beet, and a bunch of parsley. All the ingredients are passed through a juicer, and the juice is consumed fresh.

These recipes appear in books about natural nutrition. They are not universal medicinal dosages. Concentrated parsley juice requires caution, especially during pregnancy, with kidney disease, or when taking medication. Before using it medicinally, discuss the recipe with a doctor.

## How should you brew this plant?

Traditional herbal guides describe water-based preparations made from different parts of parsley. In particular, they mention an infusion made from the roots and prepared and consumed like tea.

Other reference books describe water-based decoctions containing parsley and horsetail. This combination was traditionally used for bladder inflammation. However, medicinal preparations of parsley are not recommended for acute cystitis.

Keep in mind that root tea, a decoction made from the whole plant, and preparations made from the seeds differ in composition. They should not be assumed to have the same effects or safety profile.

Seeds require particular caution because of their high apiol concentration. Do not increase the amount of plant material or make an infusion stronger on your own.

For everyday use, it is safer to use parsley as a food herb. If you specifically need a medicinal infusion or decoction, discuss the preparation method and whether it is appropriate with a specialist. This is especially important if you have a chronic condition or take medication.

## How should you harvest, dry, and store it?

Parsley is grown from seeds. In the first year, the plant develops leaves and a root. In the second year, it produces flowering stems and fruits.

Parsley-growing reference books describe dense sowing and periodic cutting of the greens. The leaves can be cut three or four times during the growing season. In the cultivation method described, mineral fertilizers are applied after cutting.

The leaves and roots are used for harvesting. Reference books recommend air-drying. Dried greens are stored in bags hung in a dry place. In traditional practice, the roots were kept in cellars.

The mature fruits are collected in autumn. They have a strong aroma that becomes especially noticeable when crushed, and a slightly pungent, bitter taste. During drying, the leaves and roots lose much of their original smell and flavor. Therefore, fresh and dried parsley may differ in their properties.

When harvesting wild parsley, you must identify the plant correctly. Hemlock and other members of the Apiaceae family can resemble edible greens. A mistake can lead to severe poisoning. Do not gather or eat unfamiliar plants based on appearance alone.

## How to find curly parsley abroad

In the United States and Europe, curly parsley is sold under local names. The options depend on which part of the plant you need.

- **United States:** parsley; the root is called parsley root or Hamburg parsley.
- **Germany:** Petersilie; the root is called Petersilienwurzel.
- **France:** persil; the root is called racine de persil.
- **Latin name:** *Petroselinum crispum*.

**Forms in which the plant is sold:**
- Dried leaves or herb for making an infusion.
- Dried root, sometimes in tea bags.
- Root powder in capsules.
- Liquid extract or tincture, especially on the American market.

Fresh parsley is usually sold as a food product rather than as medicinal plant material.

**Where to look:**
- In the United States — health food stores, herbal shops, tea shops, and online stores. Some products are available in pharmacies.
- In Germany — pharmacies (*Apotheke*), Reformhaus health food stores, tea shops, and online stores.
- In France — pharmacies (*pharmacie*), organic food stores (*magasins bio*), herbal shops, and tea shops.

**What to check on the packaging:** the Latin name, the part of the plant used (leaves or root), the product form, the amount of plant material, and any warnings. Check whether the product is a medicinal product, an herbal food tea, or a supplement. In Germany, medicinal herbal tea should be labeled “Arzneitee” or “Pflanzliches Arzneimittel” and display a registration number.

Sales rules vary by country. In France, some medicinal plants listed in the pharmacopoeia may be sold only through pharmacies.

## Contraindications and precautions

Eating parsley as a seasoning differs from taking concentrated juices, seeds, extracts, or essential oil preparations. The latter forms require considerably greater caution.

**Pregnancy.** Medicinal amounts of parsley, concentrated preparations, and seeds may be dangerous because of the effects of apiol. Reference books describe the risk of severe consequences when seeds are used in attempts to terminate a pregnancy. Such methods are unacceptable.

**Breastfeeding.** There is not enough reliable evidence about the safety of concentrated preparations. Consult a doctor before using them.

**Kidney disease.** Medicinal preparations of parsley are not recommended for acute inflammatory kidney diseases or acute cystitis. Other kidney disorders also require medical assessment.

**Oxaluria.** Parsley is classified among vegetables rich in oxalic acid. People with oxaluria are advised to limit it according to their prescribed diet.

**Allergies.** An individual reaction to parsley is possible. If itching, a rash, or other unusual symptoms appear, stop consuming it and seek medical advice.

**Sensitivity to sunlight.** Reference books describe cases of skin dermatitis following contact with parsley and other plants in the Apiaceae family in sunlight. This is linked to furocoumarins found in these plants.

**Drug interactions.** Particular caution is necessary when taking sirolimus, lithium preparations, warfarin, diuretics, cardiac glycosides, corticosteroids, and stimulant laxatives. Before using concentrated herbal preparations, tell your doctor about all your medications.

**Large amounts.** Consuming very large portions of parsley, such as around 200 g, is considered potentially unsafe. Gastrointestinal problems and increased urination may occur.

**Essential oil and apiol.** These products should not be treated as equivalent to fresh parsley. Severe toxic reactions have been described, including dizziness, seizures, and kidney damage. Prolonged apiol overdose can harm the liver and kidneys.

Do not give children concentrated parsley preparations or seeds without medical guidance. If you have a chronic condition, are pregnant, or take medication regularly, any medicinal use of parsley requires prior consultation with a doctor.

## When to see a doctor

Seek medical help if you develop an allergic reaction after consuming parsley. If you experience difficulty breathing, significant swelling, or other severe symptoms, get emergency help.

During pregnancy and breastfeeding, consult a doctor before using medicinal forms of the plant. Adding a small amount of parsley to food is different from taking seeds, concentrated juices, or extracts.

Children should not be given herbal preparations without medical advice. Particular caution is also necessary for people with kidney or heart disease and those who take medication regularly.

If you plan to use parsley as an herbal remedy rather than as a seasoning, discuss the intended method of use and possible interactions with your doctor. If you suspect an overdose of a concentrated preparation or essential oil, especially if you experience dizziness, seizures, or other pronounced symptoms, seek urgent medical help. Parsley can be part of a varied diet. However, medicinal forms of the plant require a separate safety assessment and do not replace diagnosis or prescribed treatment.
