Poisoning by British Plants

Abstract

The properties of poisonous plants have been recognised for thousands of years. To-day we see the active constituents of some such plants, accurately determined and concentrated in tablets and mixtures, used in the practice of therapeutics.

Cases of poisoning by plants though now uncommon, do still occur occasionally. Various factors are responsible for the drop in incidence over the last century. The general standard of living has been raised and people no longer require to supplement their diet with roots and fruits on pain of starvation, when mistakes are liable to occur. Better education combined with suspicions as to the wholesomeness of various fruits provides a barrier against reckless indulgence. Farming is carried out intensively and crops arc cleaner than before, thus reducing possible contamination of grain. The potential murderer or suicide now has the vast range of dangerous drugs to choose from provided he can obtain them. Many of the plants themselves have now a limited distribution. The using of any available land for grazing or ploughing and the drainage of marshes, burning of scrub and felling of timber has reduced the available habitats.
