The strangler is a rare poison which makes the victim unable to breathe. The knowledge of how to make the poison is known to the alchemists of Lys, the Faceless Men of Braavos and the maesters of the Citadel. The Asshai'i have a name for the plant and the alchemists of Lys a name for the crystal but to the maesters it is known as the strangler.
The poison is made from plants that are only found on islands in the Jade Sea. The leaves of the plant are picked and aged, then soaked in a wash of limes, sugar water and rare spices from the Summer Islands. The leaves are then discarded, but the liquid is kept and thickened with ash and allowed to crystallize. It turns a deep purple color.
