Transylvanian Pigweed is a natural sedative that will send both humans and vampires straight to sleep.
In series 4 Renfield uses the pigweed to give the soy blood a fruity taste. The Count, after drinking it, falls straight to sleep. Vlad realises that they can use the soy blood to remove the unwanted photographer. He and Miss McCauley both fall asleep after drinking the solution.
The solution was also used by George Lansley to sedate homeless humans while blood was taken from them.
