What part of the dandelion is poisonous?

Quick Answer

Dandelions are edible plants that are considered weeds in many parts of the world. While most parts of the dandelion are not poisonous, the milky sap or latex that is found in the stems and leaves can cause skin irritation and allergic reactions in some people. The roots, flowers and leaves of dandelions are all edible when harvested at the right growth stage and properly prepared.

What is a dandelion?

Dandelions (Taraxacum spp.) are a type of flowering plant native to Europe and Asia. They are part of the Asteraceae family, which also includes daisies, sunflowers, and chicory.

Dandelions have a rosette of leaves at the base of the plant and bright yellow composite flowers that turn into round seed heads, often called dandelion “clocks.” The seeds have small parachutes that allow them to travel by wind. This helps dandelions spread quickly and make them somewhat weedy.

Dandelions typically bloom from early spring through late fall. They are found worldwide and are extremely difficult to eradicate once established. The long taproot makes it hard to pull dandelions out completely.

Identifying dandelions

Some key features to identify dandelions include:

– Basal rosette of jagged, lobed leaves 2-12 inches long
– Hairy, hollow flower stems grow up to 24 inches tall
– Bright yellow flowers are 1-2 inches wide with many tiny florets
– Flowers bloom during daylight hours and close at night
– After flowering, round seed heads formed of many tiny fruits with parachute-like bristles

Dandelions can resemble some edible lookalikes like cat’s ear and false dandelion in addition to noxious weeds like spotted knapweed and mulesear wyomedia in the rosette stage. Proper identification is important for foraging dandelions safely.

Are dandelions edible?

Yes, most parts of the dandelion are edible. In fact, dandelions have many culinary and herbal uses.

The roots, leaves, and flowers are all edible if harvested at the right stage of growth. Dandelions are considered nontoxic and safe to eat for most people. However, as with any new food, it’s always wise to try just a small amount at first and watch for any adverse reactions.

Here are some common ways each part of the dandelion is used:

Dandelion roots

The taproot of dandelions can grow quite long and are reminiscent of a carrot. Dandelion roots can be:

– Roasted and used as a coffee substitute
– Cleaned, sliced and eaten raw in salads
– Boiled and mashed or made into soups and stews
– Dried and roasted to make dandelion root tea

Dandelion root is often used in herbal medicine as a gentle diuretic, digestive aid, and detoxifier. The roots are harvested by digging up the entire plant. The leaves and flowers can then also be used if desired.

Dandelion leaves

The dark green, deeply lobed leaves of dandelions can be harvested and used in a number of ways:

– Eaten fresh in salads – especially good when young and tender
– Sauteed, braised, or steamed as cooked greens
– Dried and steeped into an herbal tea
– Fermented into dandelion beer or wine

Dandelion leaves act as a diuretic and may also help improve digestion. The leaves are best harvested when young and tender before the plant flowers. The red-tinged leaves found at the center of the rosette are the sweetest.

Dandelion flowers

The bright yellow flowers of dandelions are the most distinctive feature. The flowers can be used:

– To make dandelion wine by steeping the petals in wine
– Infused in oil to make dandelion flower oil
– Battered and fried into fritters
– Added to baked goods like muffins, bread, and pancakes
– Made into jelly and jam
– Steeped fresh or dried into tea
– Used to make syrup or liquor

Dandelion flowers may help stimulate appetite and act as a mild digestive tonic. The flowers should be harvested when fully opened and vibrantly yellow in color.

Is any part of dandelions poisonous?

Most parts of the dandelion plants are considered edible and safe. However, there is one notable exception – the dandelion sap or latex found in the stems and leaves can cause skin irritation in sensitive individuals.

Dandelion sap

Dandelions contain a milky, white sap or latex that runs through the stems and leaves. This sap is present throughout the plant but is most concentrated early in the growth cycle.

The main components of dandelion latex are inulin, taraxacin, and other resins. When the leaves or stems are cut or broken, the latex leaks out. On skin contact, the latex can cause irritation, rashes, and blistering. It may also cause eye inflammation if it gets in the eyes.

For most people, the latex causes temporary skin redness and irritation. However, some people may experience more severe allergic reactions. Applying the sap to the skin multiple times can increase sensitivity.

The sap is not considered highly toxic, but it can make eating or harvesting certain parts of the dandelion unpleasant or uncomfortable for some. Cooking the plant thoroughly can help reduce the amount of latex present.

Avoiding dandelion sap

Here are some ways to prevent or limit exposure to irritating dandelion sap when harvesting:

– Harvest young leaves and flowers before maturity to minimize sap.
– Wear gloves and long sleeves when handling plants.
– Slice or break leaves carefully near the base to avoid cutting the taller stems.
– Wash dandelions thoroughly before cooking or eating.
– Cook dandelions well to help reduce remaining sap.
– Avoid harvesting after rain or heavy dew when the sap production is higher.
– Some people are more sensitive and may need to avoid dandelion sap completely.

Being aware of the potential skin irritation can help prevent uncomfortable reactions. Make sure to properly identify dandelions since some lookalike plants can also cause contact dermatitis.

Are dandelion roots poisonous?

No, dandelion roots are not poisonous. In fact, dandelion roots are one of the most widely used parts of the plant. The taproots can be very long, spreading deep into the ground.

Dandelion roots are considered safe to eat when properly harvested and prepared. Here are some key points about eating dandelion roots:

– Dandelion roots have a bitter, earthy taste similar to burdock or chicory roots. The bitterness comes from inulin, which also provides prebiotic benefits.

– The roots are nutritious, providing fiber, vitamins, and minerals like potassium, magnesium, and antioxidants.

– Dandelion roots are often dried and roasted to brew a caffeine-free coffee substitute. The roasted roots can also be used to make tea.

– Fresh roots can be cleaned, sliced thin, and added to salads for a nutty flavor. They can also be cooked and added to soups or stews.

– For medicinal uses, dandelion root is believed to act as a gentle diuretic, stimulate digestion, and support the liver and gallbladder.

– No toxicity has been reported from consuming dandelion roots in normal culinary or medicinal amounts. However, moderation is still advised as with any herb.

So while the dandelion’s sap may be irritating, the roots are entirely edible and nontoxic when harvested and prepared properly. In fact, dandelion roots are a nutritious food source with a long history of use in cuisine and herbal medicine.

Can you eat dandelion stems?

Dandelion stems are also edible, though they are less commonly consumed than the roots or greens. The stems may contain some concentration of the irritating latex within them which can cause discomfort when eating.

Some key points about dandelion stems:

– The tender green stems can be eaten fresh in salad or cooked in the same way as the leaves. However, the texture is chewier and fibrous compared to the foliage.

– Older, larger stems have tougher fiber and may contain more bitter latex making them less palatable. These are best avoided.

– Before eating stems, try peeling the outer layer of the stem which contains most of the sap. Then cook the stems thoroughly which helps break down the fibers.

– Stems can sometimes cause contact dermatitis similar to the leaves due to the presence of latex. Wear gloves and long sleeves when harvesting.

– Any allergic reaction or discomfort when eating dandelion stems raw would indicate they should be avoided if intolerances are suspected.

– For most people, young, tender dandelion stems are safe to eat when cleaned and cooked properly. But the benefits are relatively minimal compared to the roots and greens.

Overall, the stems are just marginally edible compared to other parts of the dandelion due to their texture and sap content. Stick to eating the leaves, flowers, and roots for the best flavor and experience.

Can you eat dandelion leaves raw?

Yes, dandelion leaves are edible both raw and cooked. Young, tender dandelion greens are even considered a salad green that can be consumed fresh from the plant.

Here are some tips for eating dandelion leaves raw:

– Harvest only young leaves early in spring when they are at their mildest flavor. Older leaves become bitter.

– Choose smaller leaves near the center of the plant before flowering occurs when sap content is lower.

– Wash leaves thoroughly and trim off any thick stems which may be fibrous.

– Consider massaging or bruising the leaves to release some of the bitterness.

– Add ingredients like sweeteners, acid, or fat to balance the bitter tastes of the greens.

– Start with just a small portion of raw dandelion greens until your tolerance is known.

– Sensitive individuals may get skin irritation from handling fresh leaves before washing.

Dandelion leaves contain oxalic acid so very large amounts could potentially cause health issues for someone with untreated kidney problems. As always, moderation is key.

For most people, eating young dandelion greens raw in salads or smoothies is an easy way to access their great nutrition. Just take care with harvesting and preparation to minimize latex exposure.

Can you eat a whole dandelion?

While individual parts of the dandelion are edible, you would not want to just eat an entire dandelion plant raw straight from the yard. There are some practical reasons why eating a whole dandelion is inadvisable:

– The longer stems and mature leaves will be tough, stringy, and likely high in bitter latex. This makes them hard to chew and difficult to digest.

– Eating the taproot intact provides no real benefit over just eating the cleaned crowns. Leaving the long taproot on wastes much of the plant.

– Any dirt remaining on the roots or leaves poses a contamination risk and may contain chemicals or bacteria not intended for consumption.

– It is impossible to properly inspect and wash every inch of a mature dandelion picked straight from the ground. This raises the risk of inadvertently ingesting something toxic.

– The flower heads past their prime contain seeds and fuzzy filaments that provide no nutritional value and are not palatable to eat.

However, you can eat most parts of a young, healthy looking dandelion after proper cleaning and preparation:

– Harvest younger leaves and new crowns.

– Dig up the taproots, clean thoroughly, and slice just the edible crown portions.

– Remove any tough stems or blemished leaves.

– Cook the greens and edible roots to reduce bitterness and latex.

So while you can technically eat much of a dandelion, it is not ideal or recommended to eat an entire plant raw and intact. With some simple harvesting and cleaning, individual dandelion parts can provide great edibility.


In conclusion, dandelions are considered a safe, edible wild plant in most parts of the world. The entire plant contains beneficial nutrients and properties. However, the milky white sap found in the stems and leaves can cause skin irritation in sensitive individuals.

To safely enjoy dandelions:

– Remove any tough stems during harvesting which contain the most sap.

– Wash and cook dandelion parts thoroughly before eating to decrease bitterness and latex.

– Handle plants with gloves and avoid getting sap in eyes.

– Introduce dandelion plants in small amounts to check for any allergic reactions.

– Only harvest young, tender greens and crowns before flowering.

– Dig up taproots carefully and cleanly trim away portions that will not be eaten.

With proper harvesting and preparation, the roots, leaves, and flowers of dandelions are all edible and provide health benefits. While not typically fatal, exposure to the irritating latex can be avoided through cautious handling of the plants during foraging and cooking.
