How Poisonous Are Foxgloves: Understanding their toxic properties
How Poisonous Are Foxgloves?
Foxgloves, also known as Digitalis, are poisonous plants that contain cardiac glycosides, primarily digitoxin, which can be potentially dangerous if ingested.
Poisoning from foxgloves is rare due to their unpalatable nature, but accidental poisonings have occurred from eating the flowers or drinking water from a vase containing the plant.
All parts of the foxglove plant, including the flowers, seeds, stems, and leaves, can cause toxicity if consumed.
Symptoms of poisoning may include nausea, vomiting, irregular slow pulse, tremors, bloody diarrhea, and possible convulsions.
The minimum threshold for toxicity is not known, so if there is suspected consumption, immediate medical attention should be sought.
It is important to note that using foxgloves as cut flowers indoors should be avoided if there are cats or puppies around, and consideration should be given to pets and children when incorporating this plant into the landscape.
In case of exposure, it is recommended to contact the national Poison Help hotline (1-800-222-1222) in the United States or the local emergency number for immediate assistance.

Did You Know?
1. Foxgloves contain a compound called digitalis, which is used in medicine to treat heart conditions. However, in large doses, digitalis can be incredibly toxic and potentially fatal.
2. The poisonous properties of foxgloves were first documented in the late 18th century by a physician named William Withering, who discovered their potential as a treatment for heart ailments.
3. While foxgloves are highly poisonous to humans, they are not harmful to certain animal species. For instance, bees are often attracted to the nectar of foxgloves and are able to feed safely without any adverse effects.
4. Foxgloves produce beautiful bell-shaped flowers in a variety of colors, including purple, white, pink, and yellow. These vibrant blooms serve as nature’s warning sign, alerting animals and humans alike to their potential toxicity.
5. In folklore, foxgloves were associated with various beliefs and superstitions. Some believed that the flowers were home to fairies, while others regarded them as symbols of both protection and doom, depending on the circumstances in which they were found.
Rare Poisoning Due To Foxglove’s Unpalatable Nature
Foxglove, a beautiful ornamental perennial, is commonly found in the northern half of the United States and in Canada. Despite being toxic, poisoning from foxgloves is rare due to the plant’s unpalatable nature. Animals and humans typically refrain from consuming this plant due to its bitter taste. While accidental poisonings can occur, they are infrequent. However, it is crucial to be aware of the potential dangers associated with this plant.

Potent Cardiac Glycosides Found In All Parts Of Foxglove
All parts of the foxglove plant contain cardiac glycosides, a group of compounds known for their toxic effects on the heart. Among the cardiac glycosides found in foxgloves, digitoxin is considered the most potent. These compounds have a positive inotropic effect on the heart, which means they strengthen the contractions of the heart muscle. Although these cardiac glycosides have therapeutic properties and can be used in controlled doses as medication, they can also be highly toxic if ingested in excessive amounts.
- Cardiac glycosides are present in all parts of the foxglove plant.
- Digitoxin is the most potent cardiac glycoside found in foxgloves.
- Cardiac glycosides have a positive inotropic effect on the heart.
- Excessive ingestion of cardiac glycosides can be highly toxic.

Accidental Poisonings From Foxglove Consumption
Accidental poisonings can occur when individuals mistake foxglove for a harmless plant or when curious pets or children ingest its various parts. All parts of the foxglove plant, including the flowers, seeds, stems, and leaves, can cause poisoning if ingested. It’s even been reported that drinking water from a vase containing foxgloves can lead to poisoning. Therefore, it is crucial to exercise caution when handling or displaying foxgloves in the household.
Caution When Using Foxglove Indoors With Pets
If you have cats or puppies in your home, it is advised to avoid using foxglove as a cut flower indoors. The unpalatable nature of foxgloves does not guarantee safety, as pets may still attempt to chew or consume the plant out of curiosity. The ingestion of any part of the plant can lead to poisoning and pose a significant risk to the health of your furry friends. It is crucial to consider the safety of pets and children when incorporating foxgloves into your landscape or home environment.

In the event of foxglove poisoning, it is important to recognize the signs and symptoms associated with it. These may include:
- nausea
- vomiting
- an irregular and slow pulse
- tremors
- bloody diarrhea
- and, in severe cases, convulsions.
It is worth noting that the minimum threshold for toxicity is not known, and even small amounts of ingestion should be taken seriously. Suspected consumption of foxgloves should be reported immediately to both local emergency services and the national Poison Help hotline (1-800-222-1222) in the United States.

Frequently Asked Questions
Are foxgloves poisonous to touch?
Yes, foxgloves are toxic to touch. While the plant’s allure may entice one to reach out and feel its delicate petals, caution is advised. The sap of foxgloves can cause skin irritation, leading to discomfort and potential allergic reactions. It is important to exercise appropriate care and avoid direct contact to prevent any adverse effects on the skin.
What is the most poisonous plant in the world?
One contender for the title of the world’s most poisonous plant is Aconitum, commonly known as Monkshood or Wolfsbane. This stunning flower, often found in mountainous regions of the Northern Hemisphere, contains potent neurotoxins that can cause cardiac arrhythmias and respiratory paralysis. Its historical use as a poison during medieval times has contributed to its deadly reputation.
Another formidable plant to be reckoned with is the Castor Bean plant, scientifically known as Ricinus communis. Native to Africa, it has spread to various regions worldwide. While the plant itself may appear innocuous, its seeds contain highly toxic ricin, making them one of the most poisonous substances on the planet. Ingesting just one or two seeds can lead to severe symptoms and possible lethal outcomes if left untreated.
Is foxglove animal toxic?
While foxglove may add a touch of natural beauty to your home or garden, it is important to exercise caution when it comes to animals. The plant is known to be toxic to pets such as cats and puppies, so it is advisable to keep them away from it. Ingesting foxglove can lead to a range of symptoms, including nausea, vomiting, irregular pulse, tremors, bloody diarrhea, and even convulsions. Therefore, it is essential to prioritize the safety of your pets and children when considering the use of foxglove as a cut flower indoors or incorporating it into your landscape.
Can foxglove be absorbed through the skin?
Yes, foxglove can indeed be absorbed through the skin. Grecian foxglove, in particular, contains toxic chemicals that have the ability to penetrate the skin barrier. Therefore, it is crucial to take precautionary measures such as wearing long sleeves and gloves, as well as covering exposed skin while handling or removing foxglove plants. These safety precautions are essential to prevent the absorption of the plant’s harmful toxins through the skin.
