Plants have been on this earth for about 400 million years. They can be found in every corner of the world, even in the most extreme environments. There are many different types of plants, each with their own use. Some are used to produce food while others are used for medicinal purposes. However, not all plants are harmless. Harmful plants are plant species that can cause humans harm when touched, consumed, or when they come in contact with skin. The most commonly known harmful plants include poison ivy, poison oak and stinging nettle.
Introduction: What are Harmful Plants?
Life on earth would not exist if not for plants. These living organisms are responsible for generating oxygen – the most precious component for life through a biochemical process called the photosynthesis process. Regardless, some poisonous plants can pose serious health risks to both humans and animals. These plants are typically harmful by contact or ingestion, but some can also be poisonous through skin contact. There are many ways to identify poisonous plants, but the quickest way is to learn the common names for these dangerous plants. However, most plants that are toxic to humans are often brightly coloured or have characteristics which make them stand out – in turn making them easy to identify.
Symptoms of Poisoning
Please note, this section is not intended to provide medical advice. Poisoning is a serious condition that requires immediate medical attention.
Poisonous plants can be dangerous for both humans and animals if they are ingested. The symptoms of poisoning vary depending on the plant, the amount of time it has been ingested, and how it was consumed. However, most common effects of poisonous plants include gastrointestinal problems, such as vomiting or diarrhea, hallucinations, convulsions, coma and even death.
How You Can Avoid Coming in Contact with Harmful Plant Species
One way to avoid coming in contact with toxic plants is to stay away from them. However, if you have pets or children, this might not be a possibility. So, it’s best to stay informed on where these plants are located and what they look like. Below is a list of some of the most harmful plant species around the world:
Poison Ivy: It has reddish-orange leaves and clusters of white berries on its vines. It also has a clear sap that can cause skin irritation if touched.
Poison Oak: This plant looks very similar to poison ivy and can cause skin irritation as well as blisters if touched. One of most notable features of this plant is its hairy leaves and red or yellow berries.
Daffodils: These are one of the most popular flowers for spring, but they can be dangerous to humans and animals. The daffodil plant contains the chemical lycorine, which is toxic to humans. If exposed to this chemical, it can cause vomiting, muscle tremors, convulsions and even death if left untreated.
Castor oil plant: The seeds are the most poisonous part of this plant and can cause severe nausea, vomiting, diarrhoea and stomach pain if swallowed. The active ingredient that causes these effects is ricin – in fact, this chemical is so potent that it had been used for the assasination of Georgi Markov – a Bulgarian dissident writer.
