What is it and where does it come from?
Oolong tea is a popular family of teas grown in Taiwan and
China.
Oolong teas are partially fermented teas. Oolong blends include: Wu
Yi - Da Hong Pao (Big Red Robe), Song Zhong Dan Cong (SONG Species
Lone Bush), Feng Huang - Shui Xian (Water Fairy), Yong Chun - Fo
Shou (Buddha's Hand) and An Xi - Tie Guan Yin (Iron Guan Yin
goddess of mercifulness).
What does it do and what scientific studies give evidence
to support this?
Oolong teas were first grown by ancient Chinese emperors and were
highly valued for their rich flavor and apparent health boosting
abilities.
Long consumed to enhance health, oolong tea is an excellent source
of antioxidants, vitamins and minerals. The antioxidants in oolong
tea scavenge the body for free radicals - molecules that can damage
muscle tissue, hinder immune system function and more - and prevent
oxidative stress.
Oolong tea contains caffeine. Caffeine stimulates the central
nervous system and causes fat to be released into the blood stream
for use as fuel. Thermogenesis is the process of fat being used for
energy, and an increase in body temperature is the result of this
process (heat is the waste product of fat being converted into
glucose). In this way oolong tea provides energy, sheds excess
water, and helps to burn bodyfat. For this reason, it is a common
ingredient in over-the-counter nutritional fat-loss
supplements.
Oolong tea can enhance focus because of its caffeine content.
Caffeine helps to stimulate the frontal cortex of the brain and
this results in intense focus, improved memory function, and
enhanced thinking abilities. Persons who supplement with oolong tea
report an increased desire to train.
By causing fat to be burned for fuel, oolong tea can help maintain
long-term blood pressure levels.
Oolong tea may also help maintain healthy glucose utilization and
insulin regulation
