Long farewell

The long farewell is a poison originating from Asshai. As its name implies, it takes some time to take effect, but it is highly lethal. One single drop making contact with the skin is enough to bring about death. Symptoms include bleeding from the nose, blurred vision, and nausea. Of all the known poisons, it is the only one with an antidote that has been presented and used successfully.
The length of time for the poison to take effect ultimately depends on the victim's constitution"The Queen's Justice". For example, Bronn is imprisoned for days before he begins showing symptoms, whilst Myrcella succumbs in less than an hour after the poison is given to her by Ellaria Sand. Coupled with the fact that she was a product of incest (which could explain why she died much quicker than most people would due to a weakened immune systemhttp://sansorrella.com/inbreeding%20effects%20on%20the%20immune%20system.htm), Myrcella also ingested the poison directly, whereas Bronn was cut, suggesting that the poison is less potent in the circulatory system.
==History==
===Game of Thrones: Season 5===
Tyene Sand is particularly fond of this substance, and coats her twin daggers in it. During a skirmish in the Water Gardens of Dorne, she slices Bronn with one such dagger. Later, after making him beg for it, she gives him the only antidote."The Gift"
As Jaime, Myrcella, and Trystane leave for King's Landing, Ellaria poisons Myrcella with the long farewell through a kiss of good will on the lips. Though both are poisoned, Tyene is able to produce an antidote for Ellaria, which she takes after her nose starts to bleed. Meanwhile, Myrcella dies within minutes in Jaime's arms."Mother's Mercy"
===Game of Thrones: Season 7===
After capturing Ellaria and Tyene, Euron delivers them to Cersei to face her justice for murdering her daughter. Cersei poisons Tyene with the long farewell through a kiss, just as Ellaria had done to Myrcella. She briefly misnames it as the "long goodbye", but is corrected by Qyburn. She then tells Ellaria that she intends to keep her alive so she can watch her daughter inevitably succumb to the poison and rot away, even if they have to force-feed Ellaria.
