Basil

Used for over 2000 years, it symbolises love. At one time young girls would place some on their windowsill to indicate they were looking for a suitor. In Tudor times, small pots of this were given by farmers' wives to visitors as parting gifts. It is also reputed that any man will fall in love with a woman from whom he accepts some basil from as a gift. It has large shiny green leaves  and small white flowers. Can be used as snuff to cure headaches.
