Lucius' herb

Lucius' herb was a plant Lucius Lavin discovered on his travels on M6H-491.

Overview
The herb's only known planet where it grows is M6H-491. The herb contains a chemical, which interacts with the body and causes a secretion of a pheromone, which increases the gamma activity in the prefrontal cortex - the part of the brain responsible for positive emotions. This makes everyone within close proximity to the individual become influenced by them. The herb also possesses addictive properties, as the influenced would become ill and come into withdrawal after a time of no longer recieving the pheromone. The herb can also come into a liquid form, so it could be drunk by the user.

History
Lucius, who was mainly an annoying man travelled to M6H-491 and found a herb. He collected some and came back to his planet. Since he was a baker, he laced the herb into his bread and when the villagers ate it, he noticed people started to hate him less. Eventually he made the herb into a liquid form and used the herb to influence his way into six women, as well as made all the villagers help him in every way.

After the Wraith set an outpost on M6H-491, he desperately tried to aquire more of the herb. After he encounters the Atlantis Expedition, he lulled his way to influence some of the members to rsk their lives to gate to the planet and get more of the herb, which he claims was his medicines. Eventually John Sheppard and Carson Beckett were able to discover the truth and developed a serum that effectivly neutralised the herb, ending Lucius' plans. After the villagers discovered what he had done, they banished him to another planet.
