Taraxacum officinale-Dandelion

Family: Compositae or Asteraceae

Other names: Blowball, Cankerwort, Lion’s Tooth, Priest’s Crown, Puffball, Swine Snout, White Endive, Wild Endive, Piss-a-Bed

The dandelion, Taraxacum officinale,  is a commonly used medicinal herb. It is especially effective and valuable as a diuretic because it contains high levels of potassium salts and therefore can replace the potassium that is lost from the body when diuretics are used. All parts of the plant, but especially the root, are slightly aperient, cholagogue, depurative, strongly diuretic, hepatic, laxative, stomachic and tonic. The root is also experimentally cholagogue, hypoglycaemic and a weak antibiotic against yeast infections. The dried root has a weaker action. The roots can be used fresh or dried and should be harvested in the autumn when 2 years old. The leaves are harvested in the spring when the plant is in flower and can be dried for later use. A tea can be made from the leaves or, more commonly, from the roots. The plant is used internally in the treatment of gall bladder and urinary disorders, gallstones, jaundice, cirrhosis, dyspepsia with constipation, oedema associated with high blood pressure and heart weakness, chronic joint and skin complaints, gout, eczema and acne.

hazardsmallThis plant has been mentioned in various books on poisonous plants but any possible toxins will be of very low concentration and toxicity. There are reports that some people have suffered dermatitis as a result of touching the plant, this is probably caused by the latex in the leaves and stems.

Habitat: Widely distributed throughout most of the world as a “troublesome weed.” But what is a weed but a plant growing where you don’t want it!


Taraxacum officinale is a PERENNIAL growing to 0.5 m (1ft 8in) by 0.3 m (1ft).
It is hardy to zone 5 and is not frost tender. It is in flower from Apr to May, and the seeds ripen from May to June. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects, self, apomictic. The plant is self-fertile.
It is noted for attracting wildlife.

Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very alkaline soils.
It can grow in semi-shade (light woodland) or no shade. It prefers moist soil. The plant can tolerate maritime exposure.


A very easily grown plant, it succeeds in most soils though it prefers a well-drained humus-rich neutral to alkaline soil in full sun or light shade. A very hardy plant, tolerating temperatures down to at least -29°c. The dandelion is a common weed of lawns and grassy places. Though it has a bitter flavour, the plant is often cultivated as a salad crop and as a medicinal plant, especially in parts of Europe. There are some named varieties with larger, more tender and less bitter leaves. Dandelions can provide edible leaves all year round, especially if they are given a small amount of protection in the winter. A valuable bee plant and an important food plant for the caterpillars of many butterfly and moth species, it grows well in a spring meadow. A deep rooting plant, it has roots up to 1 metre long and brings up nutrients from lower levels of the soil[201]. An excellent plant to grow in lawns, if the lawn is cut no more than fortnightly then the dandelions will provide a good quantity of edible leaves. Grows well with alfalfa. Another report says that it inhibits the growth of nearby plants. This is probably a reference to the fact that the plant gives off ethylene gas, this gas is a hormone that promotes the premature ripening of fruits and also induces the premature fruiting of plants, thereby stunting their growth. T. officinale is not a valid name for this species, but no valid name has as yet been ascribed to it. This is actually an aggregate species of many hundreds of slightly differing species. Most seed production is apomictic which means that plants produce seed non-sexually and all seedlings are clones of the parent, thus small differences are maintained.


Seed – sow spring in a cold frame and either surface-sow or only just cover the seed. Make sure the compost does not dry out. Germination should take place within 2 weeks, though 2 weeks cold stratification may improve germination. Prick out the seedlings into individual pots when they are large enough to handle, choosing relatively deep pots to accommodate the tap root. Plant them out in early summer. Division in early spring as the plant comes into growth.

Collection: The roots are best collected between June and August when they are at their bitterest. Split longitudinally before drying. The leaves may be collected at any time.

Culinary uses:

Edible Parts: Flowers;  Leaves;  Root.
Edible Uses: Coffee;  Tea.

Leaves – raw or cooked. When used in salads, they are rather bitter, though less so in the winter. Tender young leaves are considerably less bitter than older leaves. The leaves are often blanched (by excluding light from the growing plant) before use. This will make them less bitter, but they will also contain less vitamins and minerals. A very nutritious food, 100g of the raw leaves contain about 2.7g. protein, 9.2g. carbohydrate, 187mg Calcium, 66mg phosphorus, 3.1mg iron, 76mg sodium, 397mg potassium, 36mg magnesium, 14000iu vitamin A, 0.19mg vitamin B1, 0.26mg vitamin B2, 35mg vitamin C. Root – raw or cooked. Bitter. A turnip-like flavour. Flowers – raw or cooked. A rather bitter flavour, the unopened flower buds can be used in fritters and they can also be preserved in vinegar and used like capers. Both the leaves and the roots are used to flavour herbal beers and soft drinks such as ‘Dandelion and Burdock. The roots of 2 year old plants are harvested in the autumn, dried and roasted to make a very good coffee substitute. It is caffeine-free. A pleasant tea is made from the flowers. They are also used to make wine – all green parts should be removed when making wine to prevent a bitter flavour. The leaves and the roots can also be used to make tea.

Taraxacum_Officinale_botanicalMedicinal uses of Dandelion:

Actions: Diuretic, hepatic, cholagogue, anti-rheumatic, laxative, tonic, bitter.

Part Used: Root or leaf


Dandelion leaf is a very powerful diuretic, its action comparable to that of the drug `Frusemide’. The usual effect of a drug stimulating the kidney function is a loss of vital potassium from the body, which aggravates any cardio-vascular problem present. With Dandelion, however, we have one of the best natural sources of potassium. It thus makes an ideally balanced diuretic that may be used safely wherever such an action is needed, including in cases of water retention due to heart problems. As a hepatic & cholagogue Dandelion root may be used in inflammation and congestion of liver and gall-bladder. It is specific in cases of congestive jaundice. As part of a wider treatment for muscular rheumatism it can be most effective. This herb is a most valuable general tonic and perhaps the best widely applicable diuretic and liver tonic.  The plant has an antibacterial action, inhibiting the growth of Staphylococcus aureus, Pneumococci, Meningococci, Bacillus dysenteriae, B. typhi, C. diphtheriae, Proteus etc. The latex contained in the plant sap can be used to remove corns, warts and verrucae. The latex has a specific action on inflammations of the gall bladder and is also believed to remove stones in the liver. A tea made from the leaves is laxative. The German Commission E Monographs, a therapeutic guide to herbal medicine, approve Taraxacum officinale for dyspepsia, urnary tract infections, liver and gallbladder complaints, appetite loss.

Ellingwood recommends the root for the following patholgies: chronic jaundiceauto-intoxicationrheumatismblood disorders,chronic skin eruptionschronic gastritisaphthous ulcers.


For liver and gall-bladder problems it may be used with Barberry or Balmony. For water retention it may be used with Couchgrass or Yarrow.

Preparations & Dosage:

Decoction: put 2-3 teaspoonfuls of the root into one cup of water, bring to boil and gently simmer for 10-15 minutes. This should be drunk three times a day. The leaves may be eaten raw in salads.

Tincture: take 5-10 ml of the tincture three times a day.

Other uses:

Compost,  Cosmetic,  Dye,  Fruit ripening,  Latex,  Miscellany

The flowers are an ingredient of ‘QR’ herbal compost activator. This is a dried and powdered mixture of several herbs that can be added to a compost heap in order to speed up bacterial activity and thus shorten the time needed to make the compost. A liquid plant feed can be made from the root and leaves. A low quality latex, which can be used for making rubber, can be obtained from the roots of this plant.

A magenta-brown dye is obtained from the root. The plant releases ethylene gas, this stunts the growth of nearby plants and causes premature ripening of fruits.

A distilled water made from the ligules (thin appendages at the base of the leaf blades) is used cosmetically to clear the skin and is particularly effective in fading freckles.
