What is blackthorn?

Blackthorn (Prunus spinosa) is a tree of the Rosaceae family, the one to which the apple or almond belongs.

The fruits of the plant are rich in tannins, organic acids and vitamin C. It has applications as an astringent, anti-inflammatory and tonic because it contains flavonoids.

The leaves and flowers should be prescribed by a doctor because of the presence of pursic acid in its composition, which the body breaks down into toxic principles (cyanogenic glycosides).

As with other plants of the same family, the seeds of the fruits are poisonous because they contain certain amounts of hydrogen cyanide, a potent poison.
