Oregano is an important culinary herb, used for the flavour of its leaves, which can be more flavourful when dried than fresh. It has an aromatic, warm, and slightly bitter taste, which can vary in intensity. Good-quality oregano may be strong enough almost to numb the tongue, but cultivars adapted to colder climates often have a lesser flavour. It's indispensable in Italian and other Mediterranean cooking as well as Mexican fare.
Safety Info: Oregano can cause reactions in people allergic to Lamiaceae family plants, including basil, hyssop, lavender, marjoram, mint, and sage.
Diabetes: Oregano might lower blood sugar levels. People with diabetes should use oregano cautiously.
