The flowers are yellow, with the typical papilionaceous conformation and 1.3 – 7 cm long.
The flowers bloom in the period between May and September.

Uses and Traditions –
Baptisia tinctoria is a plant used in its areas of origin for a long time.
In the arid areas of origin the Native Americans of the Creek tribe employed this plant by boiling the roots of Baptisia in water and administered the decoction internally and externally to tired and debilitated children, apparently about to fall ill. The Mohicans made a mush from the root macerated in water and used it to wet cuts and wounds.
The American settlers applied it to the sores, ulcers and eczema for its astringent and antiseptic properties and internally for scarlet fever and typhus.
Baptisia tinctoria contains small amounts of alkaloids, such as cytisine (which is the main cause of the poisonousness of some legumes like Spanish broom) and some isoflavone heterosides, such as: isobaptigenina and baptigenina.
The mother tincture is prepared with the fresh underground part.
The wild indigo was introduced for the first time in homeopathy in 1857 and was used mainly in North America as a colagogue.
Allen indicated twelve pathogenetic sources: the number of symptoms, however, is very small, and includes headaches with a hot face, difficulty concentrating, agitation, eye pain, throat pain, yellowish patina on the tongue, pain in the abdominal region, with particular involvement of the hepatobiliary area (liver), sensitivity of the iliac fossa and diarrhea.
To say, moreover, that in the past the Baptisia tinctoria was used also in the case of infectious syndrome of a certain gravity, as, even, typhoid fever.
The drug used is the root and the main active ingredients are: cytisine and baptisine glycoside.
No toxicity is reported for this plant and no contraindication to normal therapeutic doses except individual hypersensitivity.
The organs affected by the phytotherapy action are:
– pharyngeal-gold cable;
– gall bladder and biliary tract;
– pharynx and upper airway;
