General Advice for Plants Exposures

There are many plants in the garden, some poisonous some not. A few simple hints will help us enjoy them all safely

Plant Identification

The correct identification of the plant is very important. It is a good idea to know the names of the plants in your garden, and your pot plants, so that the correct information can be given if poisoning should occur. If you are unsure, take a piece of the plant to a Garden Centre or Botanist. Try to get both a common name and a botanical name. Once the plant has been identified, call your Poisons Centre for advice.

General Advice

Poisonous Plants

There are many plants in the garden that are regarded as internal poisons and can cause toxic effects if parts of the plant are eaten.

Many plants in the household garden can also cause effects to the skin. These can be mechanically irritating (e.g. thorns or prickles), or have sap that can cause pain, burns or dermatitis.

Non-Poisonous Plants

Non-poisonous plants are those that do not cause poisoning to humans. However, it is important to realise that plants may cause unpleasant effects even if they are considered non-toxic.
