Below are common tea taboos, hoping to be helpful to tea-loving friends!

1. Six taboos of Iron Goddess tea
1. Avoid drinking large amounts of tea before or after meals. The correct approach is to drink tea one hour after a meal, and it should not be too strong.
2. People who are physically weak, malnourished, or anemic should avoid drinking tea.
3. Patients with urinary stones should avoid drinking tea.
4. Avoid drinking tea before bedtime.
5. Avoid drinking overnight tea.
6. Avoid drinking spoiled tea or the first brew of tea.

2. Taboos of Pu-erh tea
1. Avoid drinking strong Pu-erh tea on an empty stomach. It should be consumed at appropriate times based on individual conditions.
2. Pu-erh tea should be drunk immediately after brewing. Avoid drinking tea that has been soaked for too long or overnight Pu-erh tea.
3. Do not drink too much newly made Pu-erh tea.
4. Keeping tea utensils clean is very important. Do not forget to wash your cup regularly when drinking Pu-erh tea.
5. Pu-erh tea should be consumed in variety, not exclusively.
6. Pu-erh tea should be drunk regularly, not intermittently.
7. Pu-erh tea should be consumed warm, not hot or cold.
8. Pu-erh tea should be drunk weak, not strong.
9. Avoid drinking large amounts of Pu-erh tea before or after meals.
10. Drink Pu-erh tea in moderation before bedtime.
11. Avoid drinking poor-quality or spoiled tea.
12. Avoid drinking Pu-erh tea that has been brewed too many times.

3. Taboos of green tea
1. Avoid drinking the first brew of tea: Because tea leaves are contaminated with pesticides and other harmful substances during cultivation and processing, there is always some residue on the surface of the leaves.
2. Avoid drinking tea on an empty stomach: Drinking tea on an empty stomach can dilute gastric juice, reduce digestive function, and cause a large amount of undesirable components in tea to enter the blood, leading to symptoms such as dizziness, palpitations, and weakness in the limbs.
3. Drink less new tea: Because new tea has a short storage time, it contains more unoxidized polyphenols, aldehydes, alcohols, and other substances that strongly irritate the human gastrointestinal mucosa and can easily induce stomach problems. New tea stored for less than half a month should be avoided.
4. People with cold stomachs should not drink too much, as excessive consumption can cause gastrointestinal discomfort. Those with neurasthenia and insomnia should not drink tea before bedtime. Nursing mothers should also drink less tea, as tea has a收敛 effect on breast milk.
5. Avoid taking medicine with green tea and avoid drinking overnight tea. The tannic acid in green tea can combine with many drugs to form precipitates, hindering absorption and affecting efficacy.

4. Taboos of chrysanthemum tea
1. People with spleen and stomach deficiency and cold should drink less. When brewing tea with chrysanthemum, it should not be consumed continuously for a long time, generally 3-5 days is appropriate. People with cold constitutions might add some wolfberries.
2. People with阳虚 constitution should not drink chrysanthemum tea frequently. If they persistently drink chrysanthemum tea, which has the effect of clearing heat and reducing fire, it can easily damage healthy energy, making them weaker and weaker. Especially for people with spleen and stomach deficiency and cold, drinking too much cool chrysanthemum tea can easily cause stomach discomfort and lead to acid reflux. It can be seen that using chrysanthemum tea to reduce fire and clear heat is also selective and cannot be applied to everyone in the same way.
We will try to complete the taboos for other teas as much as possible.
So what are the功效 effects of different teas such as black tea, yellow tea, green tea, white tea, blue tea (oolong), and dark tea?

1. Black tea
Black tea is created by fermenting green tea.
It is named black tea because its dry tea leaves and brewed tea soup are primarily red.
There are many types of black tea with widespread origins. According to processing methods and the shape of the finished tea, it can mainly be divided into three categories:
Kung Fu black tea, Souchong black tea, and broken black tea.
Kung Fu black tea is unique to China. The term "Kung Fu" has a double meaning: first, it means more effort is put into processing compared to other black teas; second, it requires ample time to brew and savor slowly.
Souchong black tea is a specialty of Fujian Province, divided into Zhengshan Souchong and Waishan Souchong.
Zhengshan Souchong is produced in high mountains above 1000 meters. Zhengshan Souchong can be further divided into Eastern taste and European taste. The Eastern taste emphasizes pine smoke aroma and longan soup flavor, while the European taste has a stronger pine smoke flavor, more suitable for pairing with smoked fish and smoked meat.
Broken black tea is a bulk product in the international tea market. Processed by machine, broken black tea becomes international CTC black tea, which is most suitable for making flavored tea, iced tea, and milk tea.
Black tea can help with gastrointestinal digestion, promote appetite, diuresis, eliminate edema, and strengthen heart function.
In terms of disease prevention:
Black tea has strong antibacterial power.
Gargling with black tea can prevent colds caused by filterable viruses, prevent tooth decay and food poisoning, and lower blood sugar and high blood pressure.

2. Yellow tea
It is a tea with a slightly different processing technology from green tea, with an additional闷堆 yellowing process.
Yellow tea presents with yellow soup and yellow leaves after brewing.
Yellow tea is a specialty of China. According to the tenderness of fresh leaves, it is divided into small leaf yellow tea and large leaf yellow tea.
Yellow tea is piled tea. During the piling process, a large amount of digestive enzymes are produced, which are most beneficial to the spleen and stomach. Indigestion, loss of appetite, laziness and obesity can all be alleviated by drinking it.
Yellow tea is rich in tea polyphenols, amino acids, soluble sugars, vitamins, and other rich nutrients, and has obvious efficacy in preventing esophageal cancer.
In addition, more than 85% of the natural substances in yellow tea fresh leaves are retained, and these substances have special effects on preventing cancer, anti-cancer, sterilization, and anti-inflammation.

3. Green tea
Made from suitable tea tree new shoots as raw materials, through typical process steps such as fixation, rolling, and drying.
Its dry tea color and the brewed tea soup and tea leaves are mainly green.
According to different drying and fixation methods, it is generally divided into four types of green tea: pan-fired, baked, sun-dried, and steamed green tea.
Green tea is tea that has not been fermented, so it retains more of the natural substances of the fresh leaves. It contains more nutritional components such as tea polyphenols, catechins, chlorophyll, caffeine, amino acids, and vitamins.
These natural nutrients in green tea have special effects in preventing aging, preventing cancer, anti-cancer, sterilization, and anti-inflammation, which are not matched by other types of tea.

4. White tea
It is a slightly fermented tea, made by selecting bud leaves with particularly many pekoes and processing them with a specific fine method without rolling or frying.
The fresh leaves of white tea require "three whites," meaning the tender buds and two tender leaves all have visible white pekoe.
The finished tea is covered with fine hairs, white as silver, hence the name white tea.
White tea is divided into bud tea (such as Baihao Yinzhen) and leaf tea (such as Gongmei) based on tea plant varieties and picking standards.
Tea made from single buds as raw material is called bud tea, known as Silver Needle;
Tea made from complete one bud and two leaves with dense white hairs on the back is called leaf bud, known as White Peony (from the Da Bai tea variety tree, with the best quality picked from the first round of spring tea tender shoots).
The production process of white tea is very unique and also the most natural. It is neither fried nor rolled, unlike green tea which prevents the oxidation of tea polyphenols, nor like black tea which promotes its oxidation;
Instead, the freshly picked tea leaves are thinly spread on bamboo mats and placed under weak sunlight, or in a well-ventilated and lit indoor area, allowing them to wither naturally. When air-dried to 70-80% dryness, they are slowly baked over a low fire. Due to the simple production process with minimal steps, white tea largely retains the nutritional components of the tea leaves. People in the place of origin have since ancient times used white tea to reduce fire, clear heat toxins, reduce inflammation, induce sweating to remove dampness, relieve stagnation and avoid heat, and treat wind-fire toothache, high fever, measles, and other miscellaneous diseases.
White tea has health功效 effects of three resistances (anti-radiation, anti-oxidation, anti-tumor) and three reductions (降血压, 降血脂, 降血糖), as well as nourishing effects on the heart, liver, eyes, spirit, qi, and complexion.

5. Blue tea (Oolong tea)
Also known as Oolong tea, it is a semi-fermented tea and a distinctive category among China's major tea classes.
It is produced from the same type of tea plant as green tea, with the biggest difference being whether it has undergone the fermentation process.
Because the catechins in tea leaves will combine with each other as the fermentation temperature increases, causing the color of the tea to darken, but thereby the astringency of the tea will also reduce.
As a special famous tea in China, modern scientific research at home and abroad has confirmed that besides the general tea functions of refreshing the mind, eliminating fatigue, promoting body fluids and diuresis, relieving heat and preventing heatstroke, sterilizing and reducing inflammation, dispelling cold and sobering up, detoxifying and preventing diseases, eliminating food and relieving greasiness, losing weight and fitness, Oolong tea also突出 performs special efficacy in preventing cancer, lowering blood lipids, and anti-aging.
In addition, Oolong tea also has effects on beauty, detoxification, facilitating bowel movements, antioxidant activity, and eliminating active oxygen molecules in cells.

6. Dark tea
It uses relatively coarse and old raw materials and is the main raw material for pressing compressed tea.
Because the raw materials of dark tea are relatively coarse and old, and they often need to be piled and fermented for a long time during the manufacturing process, most leaves appear dark brown. It belongs to fully fermented tea.
Dark tea differs from other teas in the selection of raw materials and processing technology (fermentation and flowering), leading to differences in the biochemical composition and比例 of dark tea, thereby producing pharmacological functions.
The dark tea formed with the participation of microorganisms during the pile-fermentation process has极大 differences in its internal components compared to black and green teas, and its functions are also different.
It has significant efficacy in lowering blood lipids, lowering blood pressure, lowering sugar, weight loss, preventing cardiovascular diseases, and anti-cancer.
The special health efficacy of dark tea is related to its relatively rich tea polysaccharides.
