1. Avoid drinking tea if you have a fever.
The caffeine in tea can not only increase the body temperature, but also reduce the efficacy of the medicine.

2. Liver patients should avoid drinking
tea. Most of the caffeine and other substances in tea are metabolized by the liver. If the liver is diseased and drinking too much tea exceeds the liver's metabolism, it will damage the liver tissue.
3. Drink tea with caution for neurasthenia
. The caffeine in tea can excite the nerve center. Drinking strong tea for neurasthenia, especially in the afternoon and evening, will cause insomnia and aggravate the condition. You can drink tea once in the morning and afternoon during the day. You may wish to drink scented tea in the morning, green tea in the afternoon, and no tea in the evening. In this way, the patient will be energetic during the day, calm and relaxed at night, and can fall asleep earlier. 4. Patients with ulcers should be careful when drinking tea.
Tea is a stimulant of gastric acid secretion. Drinking tea can cause increased gastric acid secretion and increase irritation to the ulcer surface. Regular drinking of strong tea can worsen the condition. But for mild cases, you can drink some light tea 2 hours after taking the medicine. Black tea with sugar and black tea with milk can help reduce inflammation and protect the gastric mucosa, and also have a certain effect on ulcers. Drinking tea can also block the synthesis of nitroso compounds in the body and prevent precancerous mutations.

5. Drink tea with caution when drunk.


Tea can stimulate the nerve center. Drinking strong tea after drunkenness will increase the burden on the heart.
Drinking tea will also accelerate the diuretic effect, causing the toxic aldehydes in alcohol to be excreted from the kidneys before they are decomposed, which is highly irritating to the kidneys and harmful to health. Therefore, people with heart and kidney disease or poor function should not drink tea, especially a large amount of strong tea; for healthy people, they can drink a small amount of strong tea, and after they wake up, they can eat a large amount of tea. Fruits, or sips of vinegar can speed up the body's metabolism and relieve drunkenness.

6. Use tea with caution.
There are many types of drugs with different properties. Whether tea can be used to take medicine cannot be generalized.
The tannins and theophylline in tea can undergo chemical changes with certain drugs. Therefore, when taking hypnotic, sedative and other drugs, as well as iron-containing blood supplements, enzyme preparations, protein-containing drugs, etc., tea polyphenols can easily interact with certain drugs. The iron will react and cause precipitation. It is not advisable to use tea to deliver the medicine to prevent it from affecting the efficacy of the medicine.
Some Chinese herbal medicines such as ephedra, uncaria, coptis, etc. should not be mixed with tea. It is generally believed that tea should not be drunk within 2 hours of taking medicine.
When taking certain vitamin drugs, tea has no effect on the efficacy, because the tea polyphenols in tea can promote the accumulation and absorption of vitamin C in the human body. At the same time, the tea itself contains a variety of vitamins, and the tea itself also has stimulating effects. , diuretic, lowering blood lipids, lowering blood sugar and other effects, it can enhance the efficacy of the medicine and restore health to the human body. In addition, people often believe that it is not advisable to drink tea when taking tonics such as ginseng antler, and there is some truth to this.
7. Avoid drinking tea on an empty stomach.
Drinking tea on an empty stomach will dilute gastric acid, inhibit gastric juice secretion, hinder digestion, and even cause palpitations, headaches, stomach discomfort, dizziness, upset and other "tea drunkenness" phenomena, and affect the absorption of protein. It can also cause gastric mucositis. If "tea drunkenness" occurs, you can hold candy in your mouth or drink some sugar water to relieve it.
8. Avoid drinking overnight
tea. It is better to brew tea and drink it now. If the tea is left for a long time, it will not only lose vitamins and other nutrients, but it will also easily go rancid and deteriorate, making it easy to get sick after drinking it. 9. The elderly should not drink raw tea.
The so-called raw tea refers to roasted green tea that is dried directly without rolling. This kind of tea has a natural green appearance, and its internal components are basically the same as the compounds contained in fresh leaves. The low-boiling-point aldehyde compounds are not converted and volatilized much, and the aroma is seriously green. Elderly people who drink this kind of green tea are highly irritated to the gastric mucosa and are prone to stomach pain after drinking it; young people will also feel stomach discomfort after drinking it, which is commonly known as "stomach scraping". If you buy this kind of raw tea by mistake, it is best not to drink it directly. You can put it in a non-greasy iron pot, stir-fry it slowly over a slow fire, and roast it to remove the green air. You can drink it after a slight chestnut aroma develops.
10. Patients with high blood pressure should not drink strong tea.
Tea with less than 50 ml of boiling water per gram is considered "strong tea". If patients with high blood pressure drink too much or too strong tea, the excitatory effect of caffeine will cause an increase in blood pressure, which is not good for health.
