Poisonous Plants and Herbs I Part 2

Following the article Poisonous Plants and Herbs part 1 are presented some of the most famous poisonous plants and herbs that can be found in the Greek countryside or even in gardens.

We remind you that there are many ornamental and medicinal plants in the Greek countryside, some of which are poisonous. Poisonous plants are not necessarily bad, mainly because of their many medicinal uses. But it is important to know what they are so that we can protect ourselves. The direct effect on the body makes them different from the healing herbs whose properties take time to show the positive treatment results. As a general rule, poisonous herbs cause diarrhea, vomiting, dizziness and convulsions. In more severe cases they cause shortness of breath, arrhythmias, paralysis and many other symptoms that need immediate treatment.
