Introduction to Parsley
Parsley is a widely used herb in cooking around the world. Its vibrant green leaves provide both flavor and visual appeal to many different recipes. Historically, parsley has also been used in traditional medicine. Recent scientific studies suggest that it may have properties that can help to reduce allergy symptoms.[1]
Parsley is a member of the Apiaceae family, which also includes vegetables like carrots and celery. The two most common types are curly parsley and flat-leaf parsley.[2] Curly parsley has ruffled leaves and a milder taste, while flat-leaf parsley, sometimes called Italian parsley, has smoother leaves and a more robust flavor.
Both varieties of parsley may offer certain health benefits. Their nutritional content and various chemical compounds could be helpful in alleviating allergy symptoms. This article will discuss how parsley might assist with allergies, and also how to effectively include it in your diet.
Parsley’s Nutritional Profile
Parsley is a nutrient-dense herb, meaning it offers a lot of vitamins and minerals while being low in calories. A half-cup serving (approximately 30 grams) of fresh parsley contains a variety of beneficial nutrients:
Nutrient | Amount | % Daily Value |
---|---|---|
Vitamin C | 40 mg | 44% |
Vitamin A | 1230 IU | 25% |
Vitamin K | 547 mcg | 684% |
Folate | 46 mcg | 12% |
Iron | 1.8 mg | 10% |
The nutrients found in parsley support general health in multiple ways. Vitamin C boosts the immune system and also functions as an antioxidant.[3] Vitamin A contributes to good vision and immune function.[4] Vitamin K plays a crucial role in blood clotting and maintaining healthy bones.[5]
Parsley also contains flavonoids and other plant-based compounds, which are thought to be responsible for its potential allergy-fighting properties.[6] These include substances like apigenin, luteolin, and quercetin.
How Parsley May Help with Allergies
Anti-Inflammatory Properties
Inflammation is a key factor in allergic reactions. When your body identifies an allergen, it releases chemicals that trigger inflammation. These chemicals then cause the typical allergy symptoms, such as sneezing and itching.
Parsley contains compounds that may have the ability to reduce inflammation. One of these is apigenin, a flavonoid found in numerous plants. Research indicates that apigenin can lower the levels of inflammatory markers within the body.[7]
By reducing inflammation, parsley may help to relieve allergy symptoms.[8] It could potentially decrease swelling within the nasal passages and airways, which may make breathing easier for individuals who suffer from allergies.
Antioxidant Effects
Oxidative stress develops when there is an imbalance of unstable molecules called free radicals in the body. This imbalance can make allergy symptoms worse. Antioxidants work to combat oxidative stress by neutralizing these free radicals.[9]
Parsley is a good source of antioxidants, including vitamin C and various flavonoids.[10] These substances protect the body’s cells from damage caused by free radicals. By decreasing oxidative stress, parsley may help to support the overall function of the immune system.
A strong and well-balanced immune system is better able to deal with allergens. The antioxidants in parsley might help your body respond to allergic triggers in a more appropriate way.
Histamine Regulation
Histamine is a chemical that your body releases when you have an allergic reaction. It is responsible for many common allergy symptoms, including sneezing and itching. Some compounds in parsley may help to regulate the levels of histamine in the body.
Quercetin, a flavonoid present in parsley, has shown to have anti-allergy properties.[11] It may stabilize mast cells, which are cells that release histamine.[12] By doing so, quercetin could potentially alleviate allergy symptoms.
While more research is needed, these initial findings are encouraging.[13] They indicate that parsley may be useful in managing allergy symptoms that are related to histamine.
Types of Allergies Parsley Might Help With
The potential benefits of parsley might extend to various types of allergies. Here are some allergies that parsley could possibly help with:
- Seasonal allergies (hay fever)
- Food allergies
- Pet allergies
- Dust mite allergies
- Mold allergies
Parsley’s anti-inflammatory and antioxidant characteristics may be beneficial for these allergies.[14] For example, it might help in reducing nasal congestion during seasonal allergies.[15] Or it could potentially relieve skin reactions associated with food allergies.
However, it’s important to understand that parsley is not a cure for allergies, and it shouldn’t be used as a replacement for any prescribed allergy medication.[16] It is always best to consult with your doctor before using parsley, or any herb, for the purpose of allergy relief.
Incorporating Parsley into Your Diet
Fresh Parsley
Fresh parsley has the best flavor and contains the most nutrients.[17] When buying fresh parsley, choose leaves that are bright green with no yellowing or wilting. To store it, wrap the stems in a damp paper towel, then place it in a plastic bag inside the refrigerator.
You can incorporate fresh parsley into a variety of dishes. Here are some ideas for using it:
- Sprinkle chopped parsley over salads
- Add it to soups and stews
- Use it as a garnish for meat or fish dishes
- Blend it into homemade pesto or chimichurri sauce
Fresh parsley has a bright and slightly peppery flavor. It enhances many foods and may also offer potential allergy benefits.
Dried Parsley
Dried parsley is a convenient option with a long shelf life. While it may not be as flavorful as fresh parsley, it still provides some health benefits. Store dried parsley in a sealed container, in a cool and dark location.
Dried parsley can be used in much the same way as fresh parsley in cooking. Here are some examples of how you can use it:
- Add it to marinades for meat or vegetables
- Sprinkle it over roasted potatoes or other vegetables
- Mix it into breadcrumbs for coating chicken or fish
- Stir it into soups or stews
Dried parsley is more concentrated than fresh parsley.[18] In recipes, you should use about one-third the amount of dried parsley as you would use fresh parsley.[19]
Parsley Supplements
Parsley supplements are available in several forms, such as capsules, tablets, and tinctures.[20] These might provide a more concentrated amount of parsley’s beneficial compounds.
However, supplements are not regulated as strictly as medications. Their quality and potency can therefore vary.[21] If you are thinking about using parsley supplements, consult with your healthcare provider first.
They can offer advice about possible interactions with your current medications and help you determine appropriate dosages. Remember that supplements should be used as an addition to a healthy diet, rather than a replacement for whole foods.
Preparing Parsley for Maximum Benefits
The way you prepare parsley can affect its nutritional content. Here are some steps you can take to maximize its beneficial compounds:
- Wash parsley thoroughly under cool running water
- Pat dry with a clean towel or use a salad spinner
- Chop parsley just before using to preserve nutrients
- Use a sharp knife to avoid bruising the leaves
- Add parsley near the end of cooking to retain more nutrients
Different cooking methods can have an impact on parsley’s nutritional value. Cooking parsley for extended periods, or at very high temperatures, can reduce the presence of some beneficial compounds.[22] Adding fresh, raw parsley to dishes often provides the most nutrients.[23]
However, some cooking methods may actually improve the presence of certain beneficial compounds. For example, lightly steaming parsley may increase the availability of certain antioxidants.[24] It is worth experimenting with different preparation methods to see what works best for you.
Parsley Recipes for Allergy Relief
Adding parsley into your meals can be both easy and delicious. Here’s a sample meal plan that features parsley-rich dishes:
Meal | Recipe |

Parsley provides a wide range of benefits due to its nutritional content, and it may also be easier to incorporate into your diet when compared with some other remedies.
You might consider combining parsley with other foods that have allergy-fighting properties. For example, you could make a smoothie that includes parsley, pineapple (which contains bromelain), and ginger. These foods all have potential anti-inflammatory benefits.
Remember that natural remedies are intended to complement, and not replace, prescribed allergy treatments. Always discuss any changes to your allergy management plan with your healthcare provider.
Scientific Research on Parsley and Allergies
Research into the effects of parsley on allergies is still in the early stages.[27] Most studies so far have focused on individual compounds contained within parsley, rather than whole parsley itself.
One study found that apigenin, a flavonoid in parsley, reduced allergic airway inflammation in mice.[28] Another study showed that quercetin, which is also present in parsley, inhibited the release of histamine in lab tests.[29]
However, these studies do have some limitations. Many of them were conducted in test tubes or on animals. Further human studies are needed to confirm the effects of parsley on allergies.[30]
Future research could focus on the following:
- The effects of whole parsley consumption on allergy symptoms
- Optimal dosages of parsley for allergy relief
- Long-term effects of parsley supplementation
- Interactions between parsley and common allergy medications
While we are waiting for more research, parsley remains a nutritious food with potential health benefits. Its use as a complementary approach to allergy management seems to be promising.

Current studies focus on individual compounds; more comprehensive studies involving whole parsley are needed to confirm these effects.
While parsley has components that have anti-inflammatory and antioxidant properties, the effect of these on allergies when consuming whole parsley is not confirmed.
While parsley has anti-inflammatory properties, there is no evidence to prove that it directly affects nasal congestion.
Parsley is a food, and though it contains beneficial compounds, it is not a substitute for treatments from a doctor.
Fresh herbs often retain more volatile oils and water-soluble vitamins, which are lost during the drying process.
When drying, water is removed, which concentrates the parsley’s components. This means that a small amount of dried parsley has a higher amount of these components than an equal amount of fresh parsley.
Because dried parsley is more concentrated, a smaller amount is needed to provide the same flavor intensity.
These forms of supplements provide more concentrated doses of parsley’s beneficial compounds.
Due to less oversight, the concentration of active ingredients can vary widely between different supplement brands and batches. This is why it is always best to consult a healthcare professional when considering them.
Heat can degrade some heat-sensitive nutrients like vitamin C and some flavonoids.
Fresh, raw parsley retains more heat-sensitive vitamins and compounds, as these are not degraded by cooking.
Steaming can sometimes increase the release of bound antioxidants by disrupting cellular structures, however, too much heat can reduce the potency of beneficial compounds.
A healthcare provider can offer advice based on your individual health status and needs and any medications you may be taking.
Starting with small amounts allows monitoring for any allergies, digestion issues, or other sensitivities.
Current research has mostly focused on individual compounds in parsley, so more studies on whole parsley in humans are required.
This indicates potential for apigenin as an anti-inflammatory agent, but does not show the same result when applied to humans with parsley consumption.

This suggests that quercetin may have an anti-allergy effect in cell cultures but more research is needed on the effect when whole parsley is consumed.
Source: “Quercetin is more effective than cromolyn in blocking human mast cell cytokine release and inhibits contact dermatitis and photosensitivity in humans” https://pubmed.ncbi.nlm.nih.gov/22470478/
Many studies are conducted in labs and animals, which limits understanding of the same effects on humans.
While some components of parsley have anti-inflammatory effects, parsley should not be considered a replacement for medical treatment.
Parsley is considered a food and generally safe when consumed in food quantities. Large amounts may cause side effects or interact with certain medications and should be discussed with your doctor.
However, this does not include medicinal amounts or medicinal supplements. Consult a doctor before using in these forms.
Food allergies are unique to each individual. If experiencing any symptoms of a food allergy, discontinue use and consult a doctor.
Consistent consumption of parsley over time is more likely to have a positive impact on the body. However, more studies are needed to confirm this effect and timeline.
Parsley contains beneficial antioxidants, but there is limited research specifically on parsley tea and its effects on allergies.
Parsley can be added to sauces, soups, salads, or used as a garnish, making it a versatile way to add to a diet.
Starting slowly helps to identify any possible food intolerances or allergies.
