Parsley is rich in nutrients and antioxidants. Anecdotally, it has been known to help reduce blood pressure, cholesterol, and allergies (1). It is used in making soaps, creams, perfumes (1). Parsley is good for the skin due to its antimicrobial and anti-inflammatory activities.

Let us take a look at the rich nutritional profile, uses, benefits, and side effects of parsley. Scroll down.

What Is the Nutritional Profile of Parsley

Half a cup (30 g) of fresh, chopped parsley provides 11 calories, 2 grams of carbs, 1 gram of protein, 1 gram of fat, and 1 gram of fiber (2).

  • It is a rich source of vitamin A (8424 IU), vitamin C (133 mg), vitamin K (1640 µg), folic acid (152 µg ), and potassium (554 mg) (2).
  • Parsley also contains flavonoids, carotenoids, and vitamin C that have antioxidant properties (2).

In the following section, we will look at the health benefits of parsley.

What Are The Health Benefits Of Parsley?

1. May Regulate Blood Sugar Levels

Parsley and its essential oil are rich in an antioxidant called myristicin (3). Myristicin may help regulate blood sugar levels. It may also lower insulin resistance and inflammation. However, more research is needed to understand these effects.

2. May Aid Kidney Health

Parsley is a natural diuretic (4). It may help remove toxins and germs from the body. Rats fed with parsley seed extract showed more urine output than when they were drinking just water (4). Parsley may inhibit the sodium potassium pump that is involved in the urine regulation in kidneys (4).

Animal studies further suggest that parsley has nephroprotective effects on rats with renal issues (5).

3. May Have Anti-Cancer Effects

Parsley is rich in flavonoids that are known to have anti-cancer properties. The flavonoids inhibit cell growth and reduce oxidative stress (6).

Animal research has found that apigenin, a flavonoid found in parsley seeds, could help in killing cancer cells and decreasing the size of the tumors (7).

Studies on cancer cell lines have also found apigenin to exhibit anti-proliferation, anti-inflammation, and anti-metastasis properties in colorectal cancer (8). Apigenin is found to have anti-carcinogenic effects on breast cancer (9).

Another anti-carcinogenic flavonoid found in parsley is luteolin (10), (11). Research has stated that luteolin may have preventive effects on colorectal cancer (10).

Parsley also contains carnosol, another compound with promising results in treating cancers of the breast, skin, colon, and prostate (12).

4. May Improve Heart Health

Parsley has been used in folk medicine to help treat hypertension. The rich flavonoid content in parsley helps in improving heart health and reducing the risk of cardiovascular diseases (13).

Parsley is also a good source of folic acid. Folate intake is associated with good heart health (14). Low levels in folate can be harmful for the heart (15). Hence, including parsley in one’s diet can be helpful in this regard.

5. May Support Bone Health

Parsley is a good source of vitamin K. The vitamin helps in the formation of bone cells called osteocytes (16). Parsley was found to inhibit bone resorption (a process where bones and absorbed and broken down by the body) in rats (17).

6. May Help In Digestion

Traditionally, parsley is used to help treat digestive and gastrointestinal disorders. The fiber content in parsley helps in digestion (18). It helps in moving the food in the digestive tract and also acts as a prebiotic fodder for the good bacteria in the gut.

Parsley extracts were found to have an anti-ulcer effect in mice studies. They achieved this by inhibiting the excess secretion of gastric juice (19).

7. May Boost Immunity 

Parsley contains many antioxidants and anti-inflammatory compounds, including flavonoids (20). Apigenin fights inflammation in the body (21).

Parsley also contains vitamin C. The nutrient is a potent antioxidant that boosts the immune system (22). Parsley contains flavonols, such as kaempferol and quercetin, that fight oxidative stress and cellular damage (23).

8. May Enhance Liver Health

Parsley could regulate cholesterol and have a protective effect on the liver of rats (24). Other studies have found that parsley can help in the regeneration of liver cells and regulate enzymes in the liver in mice with diabetes (25).

9. Has Antibacterial Properties

Parsley has traditionally been used for its ability to fight germs. In a study, parsley showed antimicrobial activity in kareish cheese (26).

The essential oil from parsley has exhibited both antibacterial and antifungal activity (27). It could inhibit the growth of bacteria such as Staphylococcus aureus and Listeria monocytogenes (27). It could also protect against the fungi Penicillium ochrochloron and Trichoderma viride (27).

10. May Help Protect The Eyes

Parsley contains vitamin A, a nutrient that can help in improving eye health (28). Parsley also contains carotenes, such as lutein and zeaxanthin, that help in protecting the eyes (29). These pigmented antioxidants help in keeping the eyes healthy by preventing oxidative damage. They reduce the risk of macular degeneration and cataracts (29).

These are the health benefits of parsley. The herb is also known to promote skin health. In the following section, we have covered this topic exclusively.

It helps in cell repair and stimulates collagen production (30). This helps the skin look supple and young.

How To Select And Store Parsley


Parsley is available all round the year in supermarkets. Look for fresh parsley that has firm stems. Try to buy organically sourced parsley. Avoid buying parsley with wilted or yellow leaves, mold, and dark spots.


Parsley has to be stored properly. If not, it can wilt and lose its flavor. Store parsley in a dark spot, away from sunlight. Remove any yellow or dirty wilted leaves and wash the leaves thoroughly. Drain the excess water on a kitchen towel. Repeat the washing process again and then shake excess water off the leaves. Lay them on a kitchen towel and gently dab them to remove the remaining water. Place the leaves in a ziploc bag and store it in the refrigerator. It can last fresh for around 10 days. You can store parsley for a longer time by keeping the stems standing in water. You have to change the water to prevent microbial contamination.

Parsley may cause certain adverse effects in some people. You may want to check them out before including the herb in your diet.

Risks And Side Effects Of Parsley

Parsley should be consumed in moderation. It can lead to allergies in certain cases if consumed in excess. The following are the side effects.

  • May Interfere With Blood Pressure

Parsley can regulate blood pressure by moderating the sodium potassium pumps. However, when consumed in higher amounts, it may interact with medications for hypertension (31). Consult a doctor if you observe any changes in your blood pressure levels.

  • May Cause Hypoglycemia

The myristicin in parsley may lower blood sugar levels. If you are already on medications for lower blood sugar, taking excess parsley may lead to hypoglycemia (excessively low blood sugar levels).

  • Interactions During Surgery

Parsley may prevent blood clotting and prolong bleeding time (32). Hence, it may cause excessive bleeding during surgery. Avoid parsley at least two weeks before a scheduled surgery.

  • Skin Sensitivity

Certain individuals develop sensitivity to sun after topical application of parsley or parsley seed oil (33). This can cause sunburns and rashes. Hence, check with your doctor before use.

  • Kidney Disease

Although parsley is beneficial for the kidneys, it may cause adverse reactions in individuals with kidney disease. However, research is lacking in this aspect. Hence, consult your doctor.

  • Issues Regarding Pregnancy And Breastfeeding

Though it is safe in normal amounts, excess intake of parsley during pregnancy or breastfeeding may cause complications. Parsley may reduce milk production (34). Hence, it may not be advisable to take it during lactation.

  • Other Drug Interactions

Parsley has large amounts of vitamin K, which is involved in blood clotting. The herb may interact with medications used for preventing blood clotting (32). Some studies consider interaction between parsley and warfarin (an anti-coagulant) as doubtful (35).


Parsley is a versatile herb with many uses. It is rich in nutrients, including vitamin K and flavonoids. It has a role to play in heart, bone, and eye health. It has antimicrobial, antioxidant, and antitumor effects that help fight many chronic diseases. However, more research is needed to verify the claims.

Traditionally, parsley has been used as a diuretic, abortifacient, and an expectorant. It helps maintain healthy, clear skin. You can incorporate dried or fresh parsley leaves easily into your diet by adding them to soups, salads, marinades, and sauces.
