A recent study revealed that sipping chamomile tea increases blood levels of hippurate, an anti-inflammatory compound that may help ward off colds and other illnesses. For an extra boost of disease-fighting antioxidants, add a smidgen of honey to your steamy brew.

Drinking chamomile tea is associated with increased excretion of both hippurate and glycine, two compounds whose presence may be indicative of enhanced immune function. Additional studies have determined that chamomile tea helps ease menstrual cramps by acting as a muscle relaxant. Other ways to enhance your immunity include eating a diet high in antioxidant-rich fruits and vegetables, reducing stress, and incorporating moderate physical activity into your daily life.
