The dandelion is a herbaceous plant, belonging to the family of the compound, which usually does not grow beyond 35 cm high. It has a conical rhizome, short and quite branched, with a bittersweet taste. Its leaves (bitter when they are grown) are deeply toothed and form a rosette at the base from which grow the floriferous stems that are hollow and erect and end in a yellow floral chapter.


The name dandelion with which it is popularly known in almost all languages is due to the shape of its trimmed leaves, similar to sharp and curved teeth. However, other names with which it is also known to refer to its properties. Thus, the Spanish taraxacón or the Italian Tarassaco comes from its name in Latin Taraxacum which means “to remove” and refers to its mildly laxative properties. In French, it is known as pis-en-lit, alluding to its diuretic properties, since the tender leaves of the dandelion are edible and very pleasant in the salad. In times of scarcity, they constituted an important part of the feeding at the beginning of the spring and it is said that the children who ate a lot of dandelion urinated in bed due to its diuretic effect.

Its use in the past

Herba Taraxaci extract is used to stimulate the production of bile and urine. In the sixteenth century, its use was consolidated and its diuretic properties resulting from increasing the production of urine, and its double action on the liver are described: on the one hand, it stimulates the production of bile (choleretic effect) and, on the other, it’s emptying from the gall bladder to the duodenum, facilitating the digestion of fats. This double effect on the liver and kidney and its mildly laxative action make the Herba Taraxaci extract a useful element.

Because of its bitter taste, it also has an appetizer effect and can be used to whet the appetite.

Contraindications, adverse effects, and recommendations

Herba Taraxaci extract should never be used in case of biliary problems without the supervision of a doctor and is contraindicated in case of obstruction of the bile ducts.

To avoid this problem, a plant with mucilages such as marshmallow can be added to the infusion mixture, and in the case of taking a liquid preparation, the drops can be added to an infusion of mauve or marshmallow. The capsules of powder or dry extract of dandelion can also be taken with an infusion of these plants.


Herba Taraxaci extract preparations should not be taken if for any reason the production of gastric juices should be reduced or if antacid medicines are taken.
