Poisonous Flowers and Plants

While most flowers and plants may look harmless, there are a variety of poisonous plants that can be toxic, or even deadly, to humans and animals. It is in the best interest of people to be able to identify at least some of them to avoid coming into contact with them. Poisonous plants are potentially hazardous to all living organisms, which includes not only humans, but also pets, livestock and other animals. If for some reason a person does get into contact with a poisonous flower or plant, or accidentally ingests one or the other, the first step should be to seek immediate medical help. In order to try to avoid contact, one should familiarize themselves with local plants that are poisonous. Below is a guide that helps to educate about different poisonous plants, for humans and animals, and possible prevention steps and treatments.

Poisonous Plants

Poisonous plants can be found everywhere in the U.S., as well as all over the world. Some of the most common poisonous plants are poison ivy, poison oak and poison sumac. People most often come into contact with and interact with poisonous plant when out in nature, either hiking or just taking a walk on a weekend afternoon. Children especially are vulnerable to coming into contact with poisonous plants because of how inquisitive they are by nature and how curious they are to touch almost everything. For this reason, it is especially necessary to educate children or at least to watch them quite closely when they are in a situation where they can come into contact with poisonous plants and flowers.

Poisonous Plant for Animals

Human beings are not the only ones who can be affected by poisonous plants. Animals are also at risk for being poisoned by certain plants and flowers. Animals that are particularly vulnerable are domestic pets and livestock like cows, pigs and even horses. It is advised that farmers and others who own land with livestock grazing on it evaluate their property to discover if there are any poisonous plants and flowers on it.

Prevention

Sometimes, the best approach to preventing something is to be prepared. In the case of poisonous flowers and plants, the best way to prevent from getting poisoned by them is knowing what they look like and being able to identify them. Being able to identify poisonous plants and flowers allows people to avoid them if they see them out in nature. Being able to identify poisonous plants and flowers may mean memorizing how certain plants and flowers look like. Some poisonous plants like poison ivy are relatively easier to identify (due to their commonality) than other poisonous plants.

Treatment

Treatment for victims of poisonous plants (either by accidental ingestion or by contact) usually depends on the specific situation of the person. A doctor has to evaluate the specific factors surrounding the poisoned person and then come up with an individualized treatment plan. Treatment can range from common sense measures like not to touch other parts of the body (to avoid contamination and spreading) to applying particular ointment over the problem area. However, serious cases of poisoning by poisonous plants require immediate medical attention, which can include going to one’s personal doctor or even heading to the emergency room.
