I've been drinking licorice root tea for years. Apparently, licorice has been used medicinally for thousands of years and is supposedly helpful in regulating blood-sugar levels.
Even though I can't tell for sure whether licorice root helps regulate my blood-sugar levels, I love the sweet taste of the herb. Yogi Tea has a great "Egyptian Licorice Tea" that also has cinnamon, which some say reduces blood-sugar levels and lowers blood cholesterol. They also have a "Egyptian Licorice Mint Tea" that is very tasty.
I've also read that licorice should not be used if you have high blood pressure. So, take care.
