Preparing the Tea
Remove the peel, taking care to retain the white pith. Let the peel dry naturally. The peel will remain good and usable for several months if kept in an airtight container in a cool, dark place. To make tea, tear off a few small pieces and add to a glass or mug of hot water and let steep for a few minutes. If you prefer not to prepare your own peel, many traditional Asian food stores carry dried tangerine peel. You could also put your dried tangerine peel in hot black tea. A study in the 2001 issue of "BioMed Central Dermatology" reports that a combination of hot black tea and citrus peel can reduce your risk of squamous cell skin cancer by 70 percent, while hot tea alone reduces your risk by only 40 percent.
The major scientific study published in the 2004 issue of "Journal of Agricultural and Food Chemistry" shows that tangerine peels have more powerful health benefits than the juice and could have significant potential for lowering cholesterol in people. Reporting on the study, Science Daily explains that the peels were found to contain 20 times the antioxidants in juice. Antioxidants are chemical substances that neutralize the oxygen damage that can occur in human tissue
The high concentration of antioxidants in tangerine peel leads many natural health proponents and others to view the peel as a weapon in the fight against cancer. Current thinking among scientific researchers is that antioxidants may protect human cells from damage caused by molecules called free radicals. That damage may lead to cancer. Thus, antioxidants may stop cancer from developing.
