Herbs are the leaf part of a plant that is used in cooking - these can be used fresh or dried.
Any other part of the plant, which is usually dried, is referred to as a spice. These include, for example, barks (cinnamon), berries (peppercorns), seeds (cumin), roots (turmeric), flowers (chamomile), buds (cloves) and stigmas of flowers (saffron).
Herbs are a fantastic way to add flavour and colour to any sort of dish or drink, whether sweet or savoury, without adding fat, salt or sugars. In addition to flavour and colour, they each also tend to have their own set of health-promoting properties.
