Silkroot
Silkroot, also known as knight's veil or styxroot, was a stimulant that improved the reflexes and caused temporary euphoria.
Geography
The root was found growing wild in Akanûl. Unfortunately, silkroot was addictive and eventually ate through the stomach of users. Silkroot addicts could be weaned off the drug by chewing on the leaves of the plant.
History
In the late 15th century DR, members of the Guild worked with smugglers who brought drugs, weapons, firewine, and other substances into Baldur's Gate. Pouches of 0.8 pounds (0.36 kilograms) silkroot were among such illicit goods.
