Oolong tea contains the caffeine and catechins that promote fat burning. Also, oolong tea regulates blood sugar levels, increases satiety, and prevents the absorption of carbohydrates and fats.
- Good for skin：A Japanese study in 2001 found that, among 118 eczema patients drinking 3 cups of oolong tea per day, 74 patients had a moderate improvement in skin condition 1 month later and 64 patients had a good improvement 6 months later. Researchers believe that the anti-allergic properties of polyphenols are responsible for reducing eczema. In addition, polyphenols helps improve atopic dermatitis.

Long-term drinking of oolong tea in daily diet shows to be beneficial for health, but it is still necessary to avoid overdose. Considering the caffeine contained in oolong tea, excessive caffeine has side effects such as anxiety, headache, insomnia, diarrhea and palpitations.
Caffeine may also aggravate the diseases of diabetes, anxiety, intestinal irritable bowel syndrome and high blood pressure. In addition, excessive consumption of oolong tea will affect calcium absorption, which in turn has a bad effect on improving osteoporosis.
