Parsley


Parsley (Petroselinum crispum) is a bright green, biennial herb, also used as spice. It is very common in Middle Eastern, European, and American cooking. Parsley is used for its leaf in much the same way as coriander (which is also known as Chinese parsley or cilantro), although it has a milder flavor.

Two forms of parsley are used as herbs: curly leaf and Italian, or flat leaf (P. neapolitanum). Curly leaf parsley is often used as a garnish. Many people think flat leaf parsley has a stronger flavor, and this opinion is backed by chemical analysis which finds much higher levels of essential oil in the flat-leaved cultivars[citation needed]. One of the compounds of the essential oil is apiol. The use of curly leaf parsley may be favored by some because it cannot be confused with poison hemlock, like flat leaf parsley or chervil.

Another type of parsley is grown as a root vegetable, as with hamburg root parsley. This type of parsley produces much thicker roots than types cultivated for their leaves. Although little known in Britain and the United States, root parsley is very common in Central and Eastern European cuisine, where it is used in most soups or stews.

Though it looks similar to parsnip it tastes quite different. Parsnips are among the closest relatives of parsley in the umbellifer family of herbs, although the similarity of the names is a coincidence, parsnip meaning "forked turnip". It is not related to real turnips.

Parsley's germination is notoriously difficult. Tales have been told concerning its lengthy germination, with some suggesting that "germination was slow because the seeds had to travel to hell and back two, three, seven, or nine times (depending on sources) before they could grow." Germination is inconsistent and may require 3-6 weeks.

Furanocoumarins in parsley's seed coat may be responsible for parsley's problematic germination. These compounds may inhibit the germination of other seeds, allowing parsley to compete with nearby plants. However, parsley itself may be affected by the furanocoumarins. Soaking parsley seeds overnight before sowing will shorten the germination period.

Parsley grows well in deep pots, which helps accommodate the long taproot. Parsley grown indoors requires at least five hours of sunlight a day.

Parsley is widely used as a companion plant in gardens. Like many other umbellifers, it attracts predatory insects, including wasps and predatory flies to gardens, which then tend to protect plants nearby. They are especially useful for protecting tomato plants, for example the wasps that kill tomato hornworms also eat nectar from parsley. While parsley is biennial, not blooming until its second year, even in its first year it is reputed to help cover up the strong scent of the tomato plant, reducing pest attraction.

In parts of Europe, and particularly in West Asia, many foods are served with chopped parsley sprinkled on top. The fresh flavor of parsley goes extremely well with fish. Parsley is a key ingredient in several West Asian salads, e.g., tabbouleh which is the national dish of Lebanon. In Southern and Central Europe, parsley is part of bouquet garni, a bundle of fresh herbs used to flavor stocks, soups, and sauces. Additionally, parsley is often used as a garnish. Persillade is mixture of chopped garlic and chopped parsley. Gremolata is a mixture of parsley, garlic, and lemon zest.

Tea may be used as an enema. Chinese and German herbologists recommend parsley tea to help control high blood pressure, and the Cherokee Indians used it as a tonic to strengthen the bladder. It is also often used as an emmenagogue.[citation needed]
Parsley also appears to increase diuresis by inhibiting the Na+/K+-ATPase pump in the kidney, thereby enhancing sodium and water excretion while increasing potassium reabsorption. It is also valued as an aquaretic.
When crushed and rubbed on the skin, parsley can reduce itching in mosquito bites.

Parsley should not be consumed as a drug or supplement by pregnant women. Parsley as an oil, root, leaf, or seed could lead to uterine stimulation and preterm labor.
Parsley is high (1.70% by mass, in oxalic acid, a compound involved in the formation of kidney stones and nutrient deficiencies.
Parsley oil contains furanocoumarins and psoralens which leads to extreme photosensitivity if used orally.


The delicious and vibrant taste and wonderful healing properties of parsley are often ignored in its popular role as a table garnish. Highly nutritious, parsley can be found year round in your local supermarket.

Parsley is the world's most popular herb. It derives its name from the Greek word meaning "rock celery" (parsley is a relative to celery). It is a biennial plant that will return to the garden year after year once it is established.
Health Benefits

A sprig of parsley can provide much more than a decoration on your plate. Parsley contains two types of unusual components that provide unique health benefits. The first type is volatile oil components-including myristicin, limonene, eugenol, and alpha-thujene. The second type is flavonoids-including apiin, apigenin, crisoeriol, and luteolin.

Promote Optimal Health

Parsley's volatile oils-particularly myristicin-have been shown to inhibit tumor formation in animal studies, and particularly, tumor formation in the lungs. Myristicin has also been shown to activate the enzyme glutathione-S-transferase, which helps attach the molecule glutathione to oxidized molecules that would otherwise do damage in the body. The activity of parsley's volatile oils qualifies it as a "chemoprotective" food, and in particular, a food that can help neutralize particular types of carcinogens (like the benzopyrenes that are part of cigarette smoke and charcoal grill smoke).

A Rich Source of Anti-Oxidant Nutrients

The flavonoids in parsley-especially luteolin-have been shown to function as antioxidants that combine with highly reactive oxygen-containing molecules (called oxygen radicals) and help prevent oxygen-based damage to cells. In addition, extracts from parsley have been used in animal studies to help increase the antioxidant capacity of the blood.

In addition to its volatile oils and flavonoids, parsley is an excellent source of two vital nutrients that are also important for the prevention of many diseases: vitamin C and vitamin A (notably through its concentration of the pro-vitamin A carotenoid, beta-carotene).

Vitamin C has many different functions. It is the body's primary water-soluble antioxidant, rendering harmless otherwise dangerous free radicals in all water-soluble areas of the body. High levels of free radicals contribute to the development and progression of a wide variety of diseases, including atherosclerosis, colon cancer, diabetes, and asthma. This may explain why people who consume healthy amounts of vitamin C-containing foods have reduced risks for all these conditions. Vitamin C is also a powerful anti-inflammatory agent, which explains its usefulness in conditions such as osteoarthritis and rheumatoid arthritis. And since vitamin C is needed for the healthy function of the immune system, it can also be helpful for preventing recurrent ear infections or colds.

Beta-carotene, another important antioxidant, works in the fat-soluble areas of the body. Diets with beta-carotene-rich foods are also associated with a reduced risk for the development and progression of conditions like atherosclerosis, diabetes, and colon cancer. Like vitamin C, beta-carotene may also be helpful in reducing the severity of asthma, osteoarthritis, and rheumatoid arthritis. And beta-carotene is converted by the body to vitamin A, a nutrient so important to a strong immune system that its nickname is the "anti-infective vitamin."

Parsley for a Healthy Heart

Parsley is a good source of folic acid, one of the most important B vitamins. While it plays numerous roles in the body, one of its most critical roles in relation to cardiovascular health is its necessary participation in the process through which the body converts homocysteine into benign molecules. Homocysteine is a potentially dangerous molecule that, at high levels, can directly damage blood vessels, and high levels of homocysteine are associated with a significantly increased risk of heart attack and stroke in people with atherosclerosis or diabetic heart disease. Enjoying foods rich in folic acid, like parsley, is an especially good idea for individuals who either have, or wish to prevent, these diseases. Folic acid is also a critical nutrient for proper cell division and is therefore vitally important for cancer-prevention in two areas of the body that contain rapidly dividing cells-the colon, and in women, the cervix.

Protection against Rheumatoid Arthritis

While one study suggests that high doses of supplemental vitamin C makes osteoarthritis, a type of degenerative arthritis that occurs with aging, worse in laboratory animals, another indicates that vitamin C-rich foods, such as parsley, provide humans with protection against inflammatory polyarthritis, a form of rheumatoid arthritis involving two or more joints.

The findings, presented in the Annals of the Rheumatic Diseases were drawn from a study of more than 20,000 subjects who kept diet diaries and were arthritis-free when the study began, and focused on subjects who developed inflammatory polyarthritis and similar subjects who remained arthritis-free during the follow-up period. Subjects who consumed the lowest amounts of vitamin C-rich foods were more than three times more likely to develop arthritis than those who consumed the highest amounts.

So, next time parsley appears on your plate as a garnish, recognize its true worth and partake of its abilities to improve your health. As an added bonus, you'll also enjoy parsley's legendary ability to cleanse your palate and your breath at the end of your meal.

Description

While parsley is a wonderfully nutritious and healing food, it is often under-appreciated. Most people do not realize that this vegetable has more uses than just being a decorative garnish that accompanies restaurant meals. They do not know that parsley is actually a storehouse of nutrients and that it features a delicious green and vibrant taste.

The two most popular types of parsley are curly parsley and Italian flat leaf parsley. The Italian variety has a more fragrant and less bitter taste than the curly variety. There is also another type of parsley known as turnip-rooted (or Hamburg) that is cultivated for its roots, which resemble salsify and burdock. Parsley belongs to the Umbelliferae family of plants, and its Latin name is Petroselinum crispum.

History

Parsley is native to the Mediterranean region of Southern Europe. While it has been cultivated for more than 2,000 years, parsley was used medicinally prior to being consumed as a food. The ancient Greeks held parsley to be sacred, using it to not only adorn victors of athletic contests, but also for decorating the tombs of the deceased. The practice of using parsley as a garnish actually has a long history that can be traced back to the civilization of the ancient Romans.

While it is uncertain when parsley began to be consumed as a seasoning, it seems to be sometime in the Middle Ages in Europe. Some historians credit Charlemagne with its popularization since he had it grown on his estates.

In some countries, the curly leaf variety is more popular. This may have its roots in the ancient preference for this type since people were oftentimes reticent to consume the flat leaf variety because it resembled fool's parsley, a poisonous weed.

Turnip-rooted (or Hamburg) parsley, a relatively new species, having only been developed within the past two hundred years, has only recently begun gaining popularity.

How to Select and Store

Whenever possible, choose fresh parsley over the dried form of the herb since it is superior in flavor. Choose fresh parsley that is deep green in color and looks fresh and crisp. Avoid bunches that have leaves that are wilted or yellow as this indicates that they are either overmature or damaged. Just like with other dried herbs, if you choose to purchase dried parsley flakes, try to select organically grown parsley since this will give you more assurance that the herbs have not been irradiated.

Fresh parsley should be kept in the refrigerator in a plastic bag. If the parsley is slightly wilted, either sprinkle it lightly with some water or wash it without completely drying it before storing in the refrigerator.

If you have excess flat leaf parsley, you can easily dry it by laying it out in a single layer on a clean kitchen cloth. Once dried, it should be kept in a tightly sealed container in a cool, dark and dry place. Curly leaf parsley is best preserved by freezing, as opposed to drying. Although it will retain most of its flavor, it has a tendency to lose its crispness, so it is best used in recipes without first thawing.

Tips for Preparing Parsley:

Fresh parsley should be washed right before using since it is highly fragile. The best way to clean it is just like you would spinach. Place it in a bowl of cold water and swish it around with your hands. This will allow any sand or dirt to dislodge. Remove the leaves from the water, empty the bowl, refill it with clean water and repeat this process until no dirt remains in the water.

Since it has a stronger flavor than the curly variety, Italian flat leaf parsley holds up better to cooking and therefore is usually the type preferred for hot dishes. It should be added towards the end of the cooking process so that it can best retain its taste, color and nutritional value.

If you are making a light colored sauce, use the stems from this variety as opposed to the leaves, so the sauce will take on the flavor of parsley but will not be imparted with its green color.

A Few Quick Serving Ideas:

Combine chopped parsley with bulgur wheat, chopped green onions (scallions), mint leaves, lemon juice and olive oil to make the Middle Eastern classic dish, tabouli.

Add parsley to pesto sauce to add more texture to its green color.

Combine chopped parsley, garlic and lemon zest, and use it as a rub for chicken, lamb and beef.

Use parsley in soups and tomato sauces.

Serve a colorful salad of fennel, orange, cherry tomatoes, pumpkin seeds and parsley leaves.

Chopped parsley can be sprinkled on a host of different recipes, including salads, vegetable sautés and grilled fish.

Safety

Parsley and Oxalates

Parsley is among a small number of foods that contain measurable amounts of oxalates, naturally-occurring substances found in plants, animals, and human beings. When oxalates become too concentrated in body fluids, they can crystallize and cause health problems. For this reason, individuals with already existing and untreated kidney or gallbladder problems may want to avoid eating parsley. Laboratory studies have shown that oxalates may also interfere with absorption of calcium from the body. Yet, in every peer-reviewed research study we've seen, the ability of oxalates to lower calcium absorption is relatively small and definitely does not outweigh the ability of oxalate-containing foods to contribute calcium to the meal plan. If your digestive tract is healthy, and you do a good job of chewing and relaxing while you enjoy your meals, you will get significant benefits - including absorption of calcium - from calcium-rich foods plant foods that also contain oxalic acid. Ordinarily, a healthcare practitioner would not discourage a person focused on ensuring that they are meeting their calcium requirements from eating these nutrient-rich foods because of their oxalate content.

The Amazing Health Benefits of Parsley, or, "Hey, I Shouldn't Be Just a Table Garnish!"
by www.SixWise.com


Parsley is an easy-to-use, incredibly flavorful, nutrition powerhouse, yet, unfortunately, it often gets regarded as a "throw-away" garnish on dinner plates. Derived from the Greek word meaning "rock celery" (because it's related to celery), parsley has been cultivated for 2,000 years, and was used medicinally long before that.



Just two tablespoons of parsley provide over 150% of the daily recommended value of vitamin K.

In fact, in ancient times parsley was regarded as sacred and was used to decorate tombs. It's believed that the ancient Romans were the first ones to begin popularizing parsley as a garnish.

Among its more than 30 varieties, the two most popular are flat-leaf parsley and curly-leaf parsley, both of which can be found in most supermarkets (and are simple to grow yourself).

Aside from adding a burst of fresh flavor to soups, vegetables, meats and a host of other dishes, parsley is full of valuable nutrients that have proven health benefits.

Parsley's Many Health-Giving Properties

Parsley contains three times as much vitamin C as oranges, and twice as much iron as spinach. It's an excellent source of vitamin K, vitamin A and folate, as well. But parsley's nutrition advantages do not end there.

For a quick look at parley's major nutrients (based on two tablespoons, which has only 2.7 calories!), check out the chart below, then keep reading to find out about more of parsley's healthy benefits.

Fights cancer. Parsley contains volatile oils that have been found to inhibit tumor formation in animal studies, particularly those in the lungs. The oils are not only cancer-fighting, they're also known to neutralize carcinogens including those found in cigarette smoke and charcoal grill smoke. Parsley also contains folic acid, which has been found to help prevent colon and cervical cancers.

Antioxidant-rich. Parsley contains beneficial antioxidant compounds called flavonoids. These compounds combine with oxygen-containing molecules and help prevent oxygen-based damage to cells. Parsley extracts have also been found to increase the antioxidant capacity of the blood in animal studies.

Good for the heart. The folic acid in parsley is a critical nutrient in cardiovascular health. Specifically, folic acid helps convert potentially dangerous homocysteine into harmless molecules, a process that protects blood vessels and reduces the risk of heart attack and stroke.

Protects against rheumatoid arthritis. A study published in the Annals of the Rheumatic Diseases found that people who ate the least amount of vitamin-C-rich foods (like parsley) had a three times greater chance of developing rheumatoid arthritis than those who ate the most.
