Green tea and goji berries can both be brewed separately with boiling water and are very beneficial to the human body. Many people simply brew them together. However, the large amount of tannic acid in green tea has an astringent and adsorptive effect, which will adsorb the trace elements in goji berries and form substances that are difficult for the human body to absorb. The popular Eight Treasure Tea in restaurants also contains both green tea and goji berries. Although the amount of green tea is relatively small, it is not advisable to drink too much of it.
Drink green tea in the morning
Both green tea and goji berries are very nutritious. Green tea contains catechins and β-carotene, vitamin C, vitamin E, etc. Many experiments have proven that green tea can scavenge free radicals, delay aging, and prevent cancer.
Drinking green tea often can prevent cell gene mutation, inhibit the growth of malignant tumors, lower blood lipids and blood pressure, prevent cardiovascular diseases, and also prevent colds, dental caries, and eliminate bad breath.
Goji berries are neutral in nature and sweet in taste. They have the effects of nourishing the kidneys and essence, nourishing yin and blood, nourishing the liver and improving vision, moistening the lungs and relieving cough. Many health-prescribing medicines contain goji berries. Goji berries contain amino acids, alkaloids, betaine, physalein and various vitamins, as well as various linoleic acids.
Here's a suggestion for everyone: you can drink green tea in the morning to whet your appetite and refresh your mind; in the afternoon, you can brew goji berries to improve your physical condition and help you sleep better.
Tea has two opposite effects
Tea has both invigorating and calming effects. The invigorating effect can make the mind clear and agile, while the calming effect has an inhibitory and sedative effect. How can the same tea lead to these two opposite effects?
When the tea is first brewed for about 3 minutes, most of the caffeine in the tea leaves has dissolved into the tea water. At this time, the tea has a significant invigorating effect, making people excited. As time goes on, the tannic acid in the tea gradually dissolves into the tea water, offsetting the effect of caffeine, and it becomes less likely to cause significant physiological excitement.
Therefore, the effect of tea is dualistic. Some people dare not drink tea at night because they are afraid of not being able to sleep after drinking it. In fact, as long as you discard the tea water from the first 3 minutes of brewing and then add more boiling water to brew and drink it, the invigorating effect will not be so obvious.
