Lowers Blood Pressure
An active ingredient in yaupon tea is theobromine, which is known to help lower blood pressure and reduce strain on your cardiovascular system. Theobromine is also a mood elevator.
Yaupon is often called a "superfood" due to it being incredibly rich in antioxidants and nutrients that are linked to lower cancer rates, particularly colon cancer.

Fights Inflammation and Joint Discomfort
Recent studies have shown that yaupon tea helps to moderate the immune response and reduce inflammatory issues, such as the pain and discomfort of arthritis, headaches, gout, and joint pain. 
Boosts Immune System and Improves Digestion
Polyphenolic compounds found in yaupon tea have been directly linked to stimulating the immune system, which can help you avoid infections from foreign pathogens. Yaupon can stimulate the digestive and metabolic systems, helping to eliminate constipation and indigestion.
No Bad Breath and Prevents Oral Infections
Unlike coffee which gives bad breath to the imbiber, yaupon has no lingering oral odor.
Theobromine is not only great for lowering blood pressure, but also for preventing oral infections and keeping your teeth healthy.
