Common Hogweed Flowerhead

Hogweed is a common plant found across much of the world, from North America to Europe and even Asia. It is typically an invasive species that can quickly overrun gardens and fields.

But what makes hogweed particularly dangerous is its sap – it contains chemicals which can cause severe skin irritation or even worse if you touch it without protection.

In this article, we will explore the toxicity of hogweed, as well as what you should do if you come into contact with it and how to protect yourself and your pets.

Is Common Hogweed Poisonous to Touch?

Yes, common hogweed is poisonous to touch. The sap of the plant contains a chemical called furocoumarin, which can cause severe burns and blisters when it comes into contact with the skin, especially when exposed to sunlight.

This reaction, known as phytophotodermatitis, occurs when the skin is exposed to the plant’s chemical and UV radiation from the sun. The furocoumarin in the sap causes the skin to become extremely sensitive to UV light, resulting in severe burns and blisters.

The severity of the reaction varies from person to person, but in some cases, severe burns can take weeks or months to heal and can result in permanent scarring. The reaction can also cause blindness if the sap gets into the eyes.

What To Do If I Touch Common Hogweed?

If you come into contact with common hogweed, it is important to wash the affected area with soap and water as soon as possible. This will help to remove any sap that may be on the skin and reduce the risk of a reaction.

If blisters or burns develop, seek medical attention immediately. It’s also very important to protect yourself by wearing long sleeves, pants, and gloves when working around the plant.

What To Do If Someone Eats Common Hogweed?

If someone eats common hogweed, it is important to take immediate action to minimize the risk of harm. Common hogweed is a highly toxic plant and ingesting even small amounts can cause severe health problems.

The first step in treating someone who has eaten common hogweed is to call emergency services or poison control immediately. They will be able to provide specific guidance on how to best help the person and may also recommend transporting them to a hospital for further treatment.

While waiting for emergency services to arrive, it is important to monitor the person’s vital signs, such as breathing and heart rate.

If the person is conscious and able to swallow, you can make them drink water or milk to dilute the poison and flush it out of their system. If the person is unconscious or unable to swallow, then do not try to force them to drink as it can cause choking.

If possible, try to determine how much of the plant was consumed and how long ago it was consumed. This information can be important for the medical department in determining the appropriate treatment.

What are the Symptoms of Common Hogweed Poisoning?

The symptoms of common hogweed poisoning vary from person to person and how much of the toxin has been absorbed or ingested. In most cases, the symptoms are as follows.
