What are foxgloves: beautiful flowers, medicinal wonders?
What Are Foxgloves?
Foxgloves are a genus of herbaceous plants native to Europe, the Mediterranean region, and the Canary Islands.
They are cultivated for their attractive flower spikes and can grow to a height of 45 to 150 cm (18 to 60 inches).
All parts of the plant are poisonous if ingested.
Foxgloves produce tall one-sided clusters of bell-shaped flowers, which can be purple, yellow, or white and may have spots.
Most species are biennials, meaning they flower in their second year and then die after seeding.
The common foxglove (Digitalis purpurea) is a popular garden ornamental.
It and the Grecian foxglove (D.
lanata) are commercially cultivated for the heart-stimulating drug digitalis, which is obtained from their dried leaves.
Digitalis has therapeutic effects and is used in the treatment of atrial fibrillation and heart failure.
However, foxgloves can be toxic, and there have been cases of intoxication caused by ingestion of leaves or tea made from the plant.
Accidental ingestion of foxglove mistaken for other plants has also occurred, leading to fatal cardiac glycoside poisoning.
Treatment for foxglove poisoning includes the use of digoxin-specific Fab fragments or digoxin-specific antibody fragments.

Did You Know?
1. Foxgloves, scientifically known as Digitalis purpurea, are vibrant flowering plants that belong to the family Plantaginaceae.
2. Despite their beautiful appearance, all parts of a foxglove plant are actually highly poisonous if ingested. In fact, they contain cardiac glycosides, which can cause irregular heart rhythms and even be fatal if consumed in large quantities.
3. The name “foxglove” is believed to have originated from the Old English term “foxes glofa,” which translates to “glove of the fox.” This name was given to the plant based on the observation that foxes would sometimes slip their paws into the flowers, possibly to treat inflammation or itchiness.
4. Due to their toxicity, foxgloves have been used for medicinal purposes throughout history. In controlled doses, cardiac glycosides obtained from the plants have been utilized in treating certain heart conditions, such as congestive heart failure and arrhythmias.
5. Foxgloves have an interesting connection to fairy tales and folklore. In Celtic mythology, it was believed that foxglove flowers were the favorite hangout spots for fairies. The fairies were said to wear the bell-shaped flowers as gloves to keep their magical powers hidden. This belief is where the associated folklore name, “fairy gloves,” comes from.

Foxgloves In The Garden And Beyond: Uses And Dangers
Beyond their purely ornamental value, foxgloves have been utilized for their medicinal properties for centuries. Common foxglove and Grecian foxglove are commercially cultivated to extract digitalis for pharmaceutical purposes. This heart medication is widely used in the treatment of various cardiac conditions, proving to be a significant contribution to modern medicine.
However, it is important to recognize the potential dangers that accompany the cultivation and use of foxgloves. Some unfortunate cases of poisoning have been reported due to the ingestion of foxglove leaves. Although digitalis has beneficial effects when administered in appropriate doses, improper consumption can lead to toxicity, causing severe health complications.
In cases of foxglove extract poisoning, treatment options include the use of digoxin-specific Fab fragments. These specialized antibody fragments are designed to bind to the cardiac glycosides present in the body, effectively neutralizing their toxic effects. When administered promptly, this treatment can greatly increase the chances of recovery.
Foxglove Poisoning: Symptoms And Treatment
Foxglove poisoning can have serious consequences and should be treated as a medical emergency. Identifying the symptoms of poisoning is crucial for prompt intervention. Symptoms may include:
