Green tea

The leaves of the Camellia sinensis plant are used to make the famous beverage green tea. It contains a wealth of vitamins, minerals, plant-based chemicals, and antioxidants that have been linked to weight reduction, a decreased risk of type 2 diabetes, heart disease, and several malignancies. Additionally, studies indicate that green tea may help with asthma symptoms. To start, research on animals suggests that green tea antioxidants may lessen lung inflammation, a typical asthmatic symptom.

Research involving more than 1,000 adults also revealed that those who drank at least two 8-ounce (240 mL) cups of green tea had much superior lung function than those who didn't. Last but not least, green tea contains caffeine, which may help to temporarily relieve asthma symptoms by relaxing your airways for up to 4 hours. You may buy green tea in tea bags or loose leaf form.
