When people say, "It's a jungle out there," they generally mean that the world can be cold and heartless. Yet it turns out that a literal jungle may not be so uncaring after all. A team of Canadian scientists has found that some plants recognize close relatives and help them.

If you haven't already seen this then I think you'll enjoy it.
Lettuce leaves contain small amounts of opiate-like substance, lactucarium ("lettuce opium"), which is a mild sedative. Our ancestors used lettuce to treat anxiety, insomnia, and neurosis. Lettuce is rich source of antioxidants such as quercetin, caffeic acid, vitamins A and C. It was shown that ethanol extract of lettuce injected subcutaneously, significantly decreased accumulation of lipofuscin pigment granules ("age granules") in brain of mice under accelerated ageing regimen (the mice were administered D-galactose).
