It also offers benefits such as clearing heat, relieving summer heat, detoxifying, aiding digestion, reducing greasiness, promoting urination, relieving constipation, expelling phlegm, dispelling wind and relieving surface symptoms, stopping coughs and promoting saliva production, boosting energy, and prolonging life.Pu'er tea contains the highest levels of tea polyphenols among all teas. Research indicates tea polyphenols enhance skin beauty by increasing antioxidant levels and directly absorbing UV rays, making them an effective skin protector. Due to their high content of hydrophilic groups, tea polyphenols readily absorb moisture from the air, helping maintain skin hydration. They also promote skin whitening and reduce pigmentation.
Side Effects of Pu'er Tea
1. The higher fluoride content in fermented Pu'er tea, combined with water consumption, may react with calcium ions in the body to form calcium fluoride. This compound is poorly absorbed and can lead to calcium loss.
2. Fermented Pu'er tea contains abundant tea pigments. Excessive consumption without thorough tooth brushing can easily leave stubborn tea stains on teeth.
3. Pu'er tea neutralizes blood sugar relatively quickly. Individuals with hypoglycemia or hypotension may experience symptoms like dizziness or nausea after consumption.
4. The tannic acid and tannins in Pu'er tea (ripe tea) can bind with iron ions in the body, affecting hematopoietic function. Therefore, individuals with anemia and women during menstruation should avoid drinking Pu'er tea.
5. Pu'er tea (raw tea) has a cold nature. Excessive consumption by individuals with a cold constitution may cause discomfort such as abdominal pain and diarrhea, and may harm the stomach.
Pu'er tea has virtually no side effects, but women should note the following considerations:
1. Menstrual Period
During monthly menstruation, blood loss depletes significant iron reserves. Women should therefore increase intake of iron-rich fruits and vegetables at this time.However, if one habitually drinks tea immediately after a full meal, the tannic acid in tea—which can constitute up to 50% of its composition—can interfere with the intestinal mucosa's absorption of iron. This significantly reduces iron absorption and may cause iron from food or iron supplements to precipitate as iron stones within the intestines.
