Thyme may be tiny, but it’s powerful. Some research has shown that thyme can reduce bacterial resistance to drugs such as penicillin. It has long been used to help chest and respiratory infections. Thyme tea can improve a bad cough. Thyme is packed with antioxidants, and contains chemicals that both inhibit contamination and decontaminate food, which is why it’s good to add thyme to fresh, raw foods such as salads. Thyme is an excellent source of vitamins C and A, as well as iron, manganese, and fiber.
