Deadly Nightshade

For many, the star of the poison plants. Most people have heard of deadly nightshade even if they have never seen it. The combination of its ability to kill with its use to beautify by dilating the pupils gives it a romantic attraction which is hard to beat. Add to that the hallucinations it may also cause and its fascination is complete.

Its name, 'belladonna', comes from its use by Venetian women to make themselves 'beautiful ladies' by causing their pupils to dilate.
