Are your plants poisonous?

They please the eye and purify the air. However, some plants are two faced. Is it toxic or not? Do you have any of these plants at home?

In Canada, there are over 250 poisonus plants. You can also consult a detailed list of the toxic plants that can be found in your province. Take a look at your local poison center’s website.

Indeed, some plants can poison you when ingested while others only need to be touched in order to produce a reaction in sensitive persons.

The toxic substances of plants (or toxins) are usually classified by the nature of their effects or by chemical components. For example, the allergenic plants include those that cause hay fever; phenols regroup poison ivy and nettles; the category of resins and volatile oils include poinsettia and rhododendron, while carcinogen and cocarcinogen, such as poinsettia and bracken fern can cause cancer.

Many plants are slightly toxic or produce symptoms only in unusual circumstances (for example, when the poisonous substance contained in the plant in consumed in large quantities). Moreover, if the plant is listed among the extremely toxic plants, very small quantities may produce no symptom.
