Abstract

PROBLEM TO BE SOLVED: To obtain antiviral effects, etc., by processing a dandelion into a tea or an essence state. SOLUTION: A raw dandelion leaf is steamed with at 60-80 deg.C for about 10-20 minutes and dried at 30-50 deg.C to process the dandelion leaf into a dandelion tea leaf. When the tea leaf is made into a boiled beverage in the same way as that of a common tea, the tea leaf shows antiviral effects. The same effects can be obtained by decocting dandelion leaves for many hours, extracting an essence by an alcohol extraction method and taking the essence.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing dandelion tea leaves, dandelion tea leaves, and more particularly to dandelion tea leaves exhibiting an antiviral effect.

[0002]

2. Description of the Related Art Dandelion tea obtained by processing dandelion roots has been well known as a functional food.
No data on the medicinal properties of raw dandelion leaves has yet been found, and, of course, no drug or functional food utilizing raw dandelion leaves has yet been developed.

[0003] As a drug having an antiviral effect, for example, Acyclovir (trade name) manufactured by Welcome Inc. is commercially available. However, antiviral agents such as acyclovir have strong side effects and are limited in the amount and period of application, and are also disadvantageous in terms of price.

The present invention has been proposed in view of the above circumstances, and has as its object to provide an inexpensive dandelion tea leaf that exhibits various medicinal effects such as antiviral effects.

[0005]

The present invention employs the following method to achieve the above object. That is, raw dandelion leaves are steamed at 60 to 80 ° C. for about 10 to 20 minutes, and then dried at 30 to 50 ° C. to obtain dandelion tea leaves.

Although this dandelion tea leaf can be used as it is as tea, it is necessary to suppress bitterness.
It is also possible to add 15%.

[0007] If necessary, one or both of green tea and black tea can be added.
Furthermore, this dandelion tea leaf exhibits an effect as an antiviral agent. The antiviral effect can be naturally obtained by taking dandelion tea leaves as they are or drinking them as tea. However, dandelion tea extracts obtained by boiling dandelion tea leaves with water and evaporating the water are effective.

[0008]

Embodiment

(Example 1) First, clean raw dandelion leaves are heated to 60 to 80 ° C.
After steaming with steam for about 10 to 20 minutes, the mixture was sufficiently dried at 30 to 50 ° C. and then pulverized to obtain dandelion tea leaves. As raw dandelion leaves, any of Kanto dandelion, Kansai dandelion, and western dandelion can be used.

The above dandelion tea leaves can be used as they are to make tea beverages, but because of the bitterness,
When used as normal tea, add
-15%, and if necessary, one or both of green tea and black tea as a seasoning.

Shayuanzi is located in Liaoning, Jilin, Hebei, Shaanxi, China.
It is a perennial bean that grows naturally in Inner Mongolia. The dried mature seeds of Saenko are thoroughly fried at 60-80 ° C and then ground to obtain powdered Saenko.

[0011]

[Table 1]

(Example 2) Table 2 shows the results obtained when 2 g of dandelion tea leaves blended as described above were boiled in 500 cc of water for 5 minutes to give a day of tea drink to various herpes patients. .

[0013]

[Table 2]

(Example 3) Table 3 shows the comparison between the dandelion extract of the present invention and acyclovir of Welcome, expressed in CPE. CPE (cell degeneration effect) usually means circular swelling of cells, and a predetermined amount of dandelion is used for each culture when 100 cells of HSV-1 (herpes simplex virus) are inoculated in Vero cells and cultured for 2 days. Three comparisons were made between the case where the extract was added, the case where a predetermined amount of acyclovir was added, and the case where only the culture solution was used.

The dandelion extract is a solid content obtained by boiling dandelion tea leaves with water for about 30 minutes to 1 hour and freeze-drying the boiled liquid as described later. It can be understood that acyclovir is more effective when compared with acyclovir of the same concentration, but that the dandelion extract has a far greater cost advantage.

[0016]

[Table 3]

(Example 4) Further, Table 4 shows that 2.5 ××
10 shows the survival days when inoculated with 10 ⁵ /0.1 mL of HSV-1 virus (herpes simplex virus) and orally administered saline and dandelion extract.

[0018]

[Table 4]

As can be seen from this table, the higher the intake of dandelion extract, the higher the survival rate. (Example 5) Table 5 shows the effect of dandelion tea on the growth promotion of the mammary gland by dandelion tea using the tea prepared by the method described in Table 1 for 500 women aged 14 to 35 years. It shows size statistics. The dandelion tea was prepared by the method described in Example 2, and the amount per day was set at 500 g.

[0020]

[Table 5]

EXAMPLE 6 FIG. 1 shows that 200 hepatitis patients who used dandelion tea, 150 hepatitis patients who did not use dandelion tea, and 560 healthy people drink a predetermined amount of dandelion tea every day. It shows the results that have been missed. G
Those who initially had a TP of around 120 are below 100 in 12 months. Furthermore, it can be understood that after two years, it is no different from a healthy person. The dandelion tea was prepared by the method described in Example 2, and the amount per day was set at 500 g.

(Manufacture of extract) Dandelion extract can be manufactured by a usual extract manufacturing method.

The dried dandelion leaves are ground and sieved through a 4-18 mesh sieve. 50 kg of the above raw material is 95 to 100 ° C. with 1000 L of water.
And boil for 1 hour. The above solution is first filtered through a 50-mesh wire gauze and then through a 200-mesh filter cloth to obtain about 800 L of filtrate.

Concentration is performed under a reduced pressure of 100 mgHg at a temperature of 50 ° C. for 6 hours to obtain about 40 L of a concentrated liquid. Next, a spray drying or freeze drying treatment is performed.

Among the obtained powdery extracts, those having a coarse powder diameter are further pulverized and finally the powder diameter is made uniform with a 30 to 50 mesh sieve to obtain about 10 kg of the extract.

[0026]

As described above, the present invention exhibits excellent antiviral effects, in spite of using inexpensive dandelions as a raw material, exhibits excellent effects on hepatitis, and furthermore, has a mammary gland development effect. Can also be obtained.
