Habit and cultivation: Widely regarded throughout the world as a weed, grows in most conditions but loves a downpour. It is only worth collecting well formed roots and is cultivated to this end in Germany and France. Seeds are abundant and self sowing. There is considerable disagreement on when is the best time to harvest roots depending on when its bitter contents are highest, but they need to be 2 years in age.
Actions (known for): Anti-rheumatic, bitter tonic (digestive), cholagogue, diuretic, laxative and hepatic tonic.
History: Mentioned by Arabic physicians in the 11th century and by Welsh physicians of Myddfai during the same period as a sort of wild endive. Derived from the Greek word taraxos meaning disorder and akos meaning remedy and the Latin dens leonis as both the leaves and flower head resemble the lion’s teeth and mane. It has long been used for its diuretic properties. The history of the roots’ medicinal properties connected to the liver is much shorter. It is a key ingredient in dandelion beer along with nettles and yellow dock. The flowers are still used in the making of dandelion wine in the U.K.
