The taboos of Longjing tea are as follows:

1, women should not drink tea during menstruation.

Menstrual blood will take away some iron, so women should supplement iron-rich foods, such as spinach, apples and grapes. However, tea contains as much as 30% to 50% tannic acid, which will hinder the absorption and utilization of iron by intestinal mucosa and easily precipitate with iron in chyme or iron stone in blood-enriching drugs in the intestine.

2, anemia should not drink tea.

Tannic acid in tea can precipitate iron in diet, which is not easy to absorb. Iron is an important raw material for making red blood cells. Iron deficiency in the body will hinder the production of red blood cells and cause iron deficiency anemia. Long-term tea drinkers often have different degrees of iron deficiency, which has the greatest impact on the constitution of blood deficiency and blood deficiency.

3, calcium deficiency or fracture should not drink tea.

Because the alkaloids in tea will inhibit the absorption of calcium by duodenum. At the same time, it can also promote the excretion of calcium in urine, so that the calcium in the human body is less and less, leading to calcium deficiency and osteoporosis, making it difficult to recover the fracture.

4, suffering from osteoporosis should not drink tea.

The latest research found that drinking strong tea is one of the important causes of osteoporosis. Drinking strong tea often will lead to calcium deficiency, because on the one hand, caffeine in strong tea will promote the excretion of calcium in urine; On the other hand, caffeine can inhibit the absorption of calcium in the intestine, making the absorption of calcium incomplete.

5. It is not advisable to drink tea when taking certain drugs.

Tannic acid in tea often precipitates the effective components of digitalis, iron and Chinese patent medicine supplements, which are not easily absorbed. Taking pepsin or multi-enzyme tablets while drinking tea will coagulate protein in medicine, and the curative effect is difficult to achieve.

6. Women should not drink tea during pregnancy.

The concentration of caffeine in strong tea is as high as 10%, which will aggravate the urination and heartbeat of pregnant women, increase the burden on their hearts and kidneys, and induce pregnancy poisoning, which is not conducive to the health of the mother and fetus.

7. Women should not drink tea during lactation.

During this period, if you drink a lot of tea, the high concentration of tannic acid in tea will be absorbed by mucous membrane and enter the blood circulation, which will have astringent and inhibitory effects on mammary gland secretion, resulting in insufficient milk secretion. On the other hand, caffeine in tea will also enter the baby's body through milk, which will affect the baby's health.

Storage method of Longjing tea

Storage method of lime: the fried Longjing tea is easy to deteriorate due to moisture, so it should be wrapped in paper in time, with 0.5 kg as a package, and put in a jar covered with massive lime (lime that has not absorbed moisture and weathered) for sealed collection.

After being properly stored for about 0.5 to 1 month, the aroma of Longjing tea is more fragrant, and the taste is more fresh, mellow and refreshing. Longjing tea, which is kept dry, can still maintain the quality of green, fragrant and alcohol after being stored for one year.

Charcoal storage method: The specific method is similar to the quicklime storage method, except that charcoal is used instead of quicklime as a desiccant, that is, 1 kg charcoal is put into a cloth bag and replaced every one or two months.

If the charcoal absorbs moisture, it should be burned red, cooled and put into cloth bags, each bag weighs about1kg; Take out charcoal every month or two and dry it before using it.
