Foxglove, toxic plantthe poison of digitalis

We often hear about"Poison of digitalis". In fact, glycosides can act as a powerful poison (they are supposed to have been the cause of the death of Cangrande I della Scala, lord of Verona) causing cardiac arrest. However, the same glycosides, if properly dosed, can be very useful in therapy against heart failure.

The glucosides in question are the two active ingredientsdigitoxin and lanatoside C, natural digitalis. These substances work as cardiotonics and are used in homeopathy (and not only) against heart failure, including congenital ones.

Due to the high content of glycosides, all plants of the digitalis genus are considered poisonous. Digitoxin and lanatoside C, if absorbed in excessive doses, can be very harmful to the body or even fatal.

In herbal medicine and homeopathy, the parts used are leaves, flowers and seeds. The glycosides are mainly contained in the leaves.

Digitalis bruna or digitalis ferruginea

The most interesting glycosides, extracted from plants of the genusdigitalisfor use in pharmacology, they are digitonin, digitoxin, digitophylline and digitalin. These substances have an action on the heartbeat and blood pressure.

Theredigitalis brunetteo digitalis ferruginea, due to its glucosides, is counted among the most poisonous Italian plants.

Digitalis lanata

Like all species of the digitalis genus, thedigitalis lanatait is highly toxic. The plant is toxic in all its parts (flower, stem, leaves and seeds). The leaves were often used as a natural remedy, to be harvested in spring and stored throughout the year. Due to its toxicity, the practice of collecting and DIY remedies based on digitalis is strongly discouraged. Among the other active ingredients extracted from the leaves of this genus we point out digoxin and digitoxin.

Digitalis grandiflora

It is known as thedigital plantwith large yellow flowers. This perennial herb is prized for its many hybrids. The fruit is capsule-shaped and develops on a persistent calyx. The seeds ripen in September.
