aconite leaves only one post-mortem sign, that of asphyxia, as it causes arrhythmic heart function which leads to suffocation. Poisoning can occur even after touching the leaves of the plant without wearing gloves as it is very rapidly and easily absorbed. Because of its untraceable nature it has been a popular one with the “get away with murder” crowd. Reportedly, it has a particularly famous casualty. The emperor Claudius is said to have been poisoned by his wife, Agrippina, using aconite in a plate of mushrooms.
