Wild harvested roasted leaves from Yaupon Holly (Ilex Vomitoria). 
 
Historically, Yaupon Holly has been used widely throughout the South as a tea, having an export higher than tobacco or cotton at one time. Its use was widespread because Yaupon tea is a natural source of caffeine, theobromine, and several polyphenols like chlorogenic acids, which may help protect against conditions like diabetes .
 
Having a lighter, nuttier taste than coffee, it is often an easy addition to tea mixtures. Coffee lovers might take longer to get used to the switch as the taste is more subtle. But if you are looking to switch, Yaupon Holly has many other medicinal qualities that have been documented other than just its caffeine and Theobromine contents like:
Improved energy levels
Better Brain Functioning
Anti-inflammatory
 
The caffeine content of Yaupon Holly is .75% caffeine weight and coffee is about 1.1%. Both contain caffeine and long-term use of either 4 cups of coffee or 6 cups of Yaupon tea daily will result in:
Anxiety
Insomnia
Digestive Problems
Sleep Problems
Increased Acidity
Increased blood pressure
 Yaupon Holly has been used for thousands of years, with few unintentional negative sides being recorded. But before taking any new medications, including natural health products, speak to your physician, pharmacist, or other health care provider. Tell your health care provider about any natural health products you may be taking
