The leaves of the Camellia Sinensis plant contain micro and macro elements that are a natural source for meeting the human needs for these elements.

For example, tea contains magnesium, which is necessary for the normal functioning of the human nervous system, heart muscle, affects the work of the cardiovascular system, increases the activity of the colon, etc.

Considering that white, green and black teas are rich in magnesium, we can say that they are real calming teas, because they help fight insomnia, chronic fatigue, muscle spasms, cardiac arrhythmia, etc. as a result of magnesium deficiency.

Also, the leaves of the Camellia sinensis plant contain several alkaloids, among which the most famous are: theophylline, theobromine, and caffeine.

Theophylline and theobromine are used in the treatment of cardiovascular disease and kidney disease. These alkaloids are part of the cure for these diseases.

Therefore, for the health of the cardiovascular system, green, black or white tea is recommended.

For relaxation and relief from stress and everyday mental problems, drinking Camellia sinensis tea can be very effective given the presence of the amino acid L-theanine, which has a proven calming effect without reducing concentration.

Chinese tea is one of the oldest and most perfect pharmaceutical products, containing about 300 chemical compounds whose combination in tea is unique and cannot be found in other herbs or chemical preparations (in tablets), which is why it is often used in traditional and modern medicine.

Some of the best-known healing effects of this drink are: a positive effect on the heart and blood flow, its effectiveness as an anti-stress drink, but also an effective tea for tranquilizers.

FOLIC ACID

What is folic acid used for?

Folic acid is important for normal brain function, mental and emotional health. Prevents irritability, fatigue, depression, deconcentration, insomnia. It participates in the formation of DNA and RNA, the genetic material of the organism, and is especially important when tissues and organs are growing rapidly (pregnancy, childhood). Folic acid and vitamin B12 are involved in the formation of red blood cells, which carry oxygen to all parts of the body. Folic acid is useful in some types of anemia (megaloblastic anemia due to folic acid deficiency), and in some types of anemia it can mask vitamin B12 deficiency and thus lead to damage to nerve cells.

Folic acid, vitamin B6 and B12 affect the level of the amino acid homocysteine in the blood. Increased levels of homocysteine have been linked to heart disease, depression, and Alzheimer's disease. Folic acid deficiency has been linked to both degenerative nerve damage and Parkinson's disease.

For women who want to get pregnant in case of improper diet, it is recommended to use 400mcg of folic acid per day. Multivitamin preparations for pregnant women and women planning pregnancy usually contain 400 mcg of this acid. It also appears to prevent miscarriage, although a clear link has not been established.

Heart disease

Folic acid can protect the heart and blood vessels. A link has been found between elevated homocysteine levels and the chance of heart attack and stroke. People who have high levels of homocysteine in their blood are 1.7 times more likely to have coronary artery disease (which leads to myocardial infarction) and 2.5 times more likely to have a stroke compared to people with normal homocysteine levels. However, it is not yet determined whether homocysteine causes heart disease or something else affects the increase in homocysteine and the development of heart disease. For now, some experts believe that reducing homocysteine can reduce your chances of developing heart disease, heart attack, and stroke.

Depression

Practice has shown that some people in depression also lack folic acid, and the more folic acid they lack, the more pronounced the depression. Low levels of folic acid have also been linked to poor response to antidepressants.

Tumor-carcinoma

Folic acid, according to some studies, can protect against cancer of the colon, breast, cervix, pancreas and stomach. The relationship and role of folic acid in the eventual anti-cancer effect has not been clearly established. However, because folic acid is necessary for the growth of every cell, according to some experts, it may contribute to the growth of cancer, which the immune system might otherwise destroy. Opinions are divided, and until more is known, it is best that people who have had cancer do not take this acid on themselves.

Folic acid deficiency has also been linked to osteoporosis. People with high homocysteine and low folic acid levels have been found to have an increased chance of heart disease, senile dementia, and osteoporosis, as well as bone fractures.

VITAMIN D

First of all, we owe healthy bones. Vitamin D helps the absorption of calcium in the intestines and helps maintain adequate levels of calcium and phosphorus in the blood, which is necessary for healthy bone mineralization.

Vitamin D deficiency in children can cause rickets, which leads to bone deformation due to their softening. In adults, vitamin D deficiency also manifests as osteomalacia or softening of bones. Osteomalacia leads to poor bone density and muscle weakness. Long-term vitamin D deficiency can also lead to osteoporosis.

Also, its intake in sufficient quantities can trigger effective immune protection and reduce the risk of autoimmune diseases. Researchers suggest that there may be a link between long-term vitamin D deficiency and the development of autoimmune conditions, such as diabetes, asthma and rheumatoid arthritis, but more research is needed to confirm this link.

Although our body can produce vitamin D, Some people are more likely to be deficient. The factors that can affect this are skin color, as more pigmentation reduces the body's ability to absorb the ultraviolet (UVB) rays of the sun. Absorption of sunlight is necessary for the skin to produce vitamin D. Another factor is lack of sun exposure, so people who live in northern latitudes or high pollution areas, work night shifts, or are housebound should regularly take vitamin D from food or supplements.

Older adults are also in a group at risk for symptoms of vitamin D deficiency; the skin's ability to synthesize vitamin D decreases with age, and older populations often spend more time indoors. In addition, there are obese people because high levels of body fat can limit the body's ability to absorb vitamin D from the skin.

Vitamin D is a very important vitamin in the body because it maintains calcium levels. It helps the body absorb calcium from food, which stimulates the strengthening of bones. Without sufficient vitamin D, bones can become thinner, brittle, and soft, further leading to a higher risk of fractures and bone diseases such as osteoporosis and osteomalacia.

When it comes to immunity, vitamin D also plays a very important role, because its optimal intake/production greatly affects the strengthening of immunity and has a positive effect on the nervous system. Another advantage is the regulation of blood sugar, so it can be helpful to diabetics.

In addition to these two benefits, it is very important to note two other benefits of vitamin D, which are:

• Helps in the development of the lungs and cardiovascular system

* Plays a key role in the fight against obesity
