12–13 August. Exhibition “Medicinal and Poisonous Plants”

On 12th and 13th August, an exhibition of medicinal and poisonous plants will be held in the greenhouse of the botanical garden. The exhibition offers a great opportunity to refresh one’s knowledge about medicinal herbs and poisonous plants as well as to learn how to use them and which ones to avoid. In addition, anyone interested can listen to professor Ain Raal’s lecture ‘Medicinal plants or pills?’ and participate in hydrosol distillation workshops.

There are more than 10,000 species of poisonous plants in the world. However, most of these grow in climates warmer than that of Estonia. The plants surrounding us are usually harmless to humans. Every medicinal plant, if used wrong, and every harmless plant, if consumed in excessive quantities, can be dangerous. Poisonous and medicinal plants that live with us indoors and outdoors are on display at the exhibition.

At the exhibition you will learn which medicinal plants can be used at home to relieve various health problems, and when and which parts of particular plants should be picked. The most dangerous plants that grow in Estonia are monkshood, northern water hemlock, poison hemlock, autumn crocus, adonis, deadly nightshade, bryony, boxwood, knight’s-spur, lily of the valley, purple crown vetch, February daphne, devil’s trumpets, larkspur, foxglove, cypress spurge, and other Euphorbiaceae. Many of these plants are valuable medicinal plants if used properly. Up to 12,000 medicinal plant species are thought to exist in the world, although less than 200 species of these are in frequent use.

The exhibition is a good opportunity to refresh your knowledge about medicinal and poisonous plants. One will learn how to use or avoid them. The best way to avoid plant poisoning is to learn how to identify poisonous plants as you grow up. Knowledge of medicinal plants also helps. We are used to taking pills for minor health problems while a medicinal plant that is less harmful to our health could be found in our own garden or right by it. What could be better than a cup of aromatic balm or mint tea — it provides genuine enjoyment and is a quick stress reliever.

** Hydrosols or plant distillates consist of essential oils that get mixed in distilled water and the cellular water from the tissue of the plants undergoing distillation. During the workshop, its participants can take part in the steam distillation process as well as learn something about hydrosols of various plants and their properties. Various stages of the process will be performed on the sport, and the joint effort will result in an environmentally clean distillate. The hydrosols workshop will be held by Alkeemialabor; additional information is available HERE.


The exhibition is included in the standard ticket price.
