Dagga Plant

Dagga Plant, also known as Wild Dagga Plant is a small plant and one of the ingredients for the cure of Eel Pox.

Description
Dagga Plant (Leonotis leonurus) is a small plant with light purple leaves and no flowers.

In reality, it is a tall plant with dark green leaves and tubular orange flowers in tiered whorls.

It grows in bushes and is a plant species in the mint family. It is native to South Africa and southern Africa, where it is very common. It is known for its medicinal and mild psychoactive properties.

Function
Dagga Plant is mainly used as an ingredient for Eel Pox.

In reality, the infusions made from flowers and seeds, leaves or stems are widely used to treat tuberculosis, jaundice, muscle cramps, high blood presure, diabetes, viral hepatitis, dysentery, and diarrhoea. The leaves, roots and bark are used as an emetic for snakebites, bee and scorpion stings.

The Eel Effect
While searching for the ingredients for the cure, Tuffnut climbs a sea stack on which grow some Dagga Plants. However, Ruffnut, already on top, throws rocks on his face while Barf and Belch look with a Dagga Plant in mouth.

Later in the episode, Hiccup and Fishlegs make a cure for Toothless, in which they include the Dagga Plant.

Trivia

 * Strangely, the real Dagga Plant can be found in South Africa and Australia, so it was unlikely to find it in North Europe during the Viking Age.
 * The real plant is very different in colour and size from the in-universe plant.
