Gelsemium is a non-magical plant that was introduced to the Hogwarts students during Term 11, by Professor Cleo Virohsa. The plant is poisonous and should be handled with care.
The specific genus introduced in class was G. sempervirens, a flowering vine often used for decoration and gardening by Muggles.
Symptoms of Poisoning
Poisoning by the Gelsemium can be identified by one or more of the following symptoms:
- Paralysis of muscles of mouth and throat
- Indistinct speech
- Difficult or impossible deglutition
- Precordial oppression
- Difficulty of respiration
The seeds, if properly removed from the Gelsemium flowers, are often used as potions ingredients. In addition, the root cluster can be dried while the plant is still green to be utilized.
In potions, Gelsemium is a common ingredient in medicinal potions for skin diseases and eruptions.
