Roman Chamomile

Roman chamomile (Chamaemelum nobile) is a plant native to Morocco and Europe. It's different from German chamomile, which is more commonly used in teas.

Roman chamomile contains chemicals that might have anticancer, anti-diabetes, and anti-inflammatory effects.

People take Roman chamomile for hay fever, anxiety, eczema, stress, insomnia, and many other conditions, but there is no good scientific evidence to support these uses.
