Abstract

Disclosed are a fermented tea obtained by inoculating tea with a microbial strain derived from fermented soybean sauce, and a method for producing the fermented tea. The fermented tea has superior taste and aroma, exhibits an outstanding improving effect on blood circulation and alleviating effect on cold hands and feet, and can be used various ways in the field of health foods or medical products.

First claim

The invention claimed is:

1. A method for improving blood circulation and alleviation of cold hands and feet of a subject in need thereof, comprising:
providing a solution for fermentation;
adding sugar or fructose to the solution;
inoculating the solution with Bacillus subtilis;
stabilizing the Bacillus subtilis by culturing the Bacillus subtilis before adding green tea to the fermentation solution;
mixing the inoculated solution with green tea leaves, wherein the Bacillus subtilis is in an amount of 10 3 to 10 8 CFU/ml, and the green tea leaves are in an amount of 30-60 wt % based on the total weight of the solution;
fermenting the inoculated solution at a temperature of above 40° C. but less than or equal to about 60° C. for 24 hours to 28 days to provide a fermented green tea; and
administering to the subject an effective amount of the fermented green tea to improve blood circulation and alleviates cold hands and feet of the subject.

2. The method of claim 1 , wherein the effective amount is between 0.001 mg/kg/day and 2000 mg/kg/day.

3. The method of claim 2 , wherein the effective amount is between 0.5 mg/kg/day and 1500 mg/kg/day.

4. The method of claim 1 , wherein the Bacillus subtilis is stabilized by culturing the Bacillus subtilis for 24 hours.

5. The method of claim 1 , wherein the Bacillus subtilis is a microbial strain derived from fermented soybean sauce.

6. A method for alleviating cold hands and feet of a subject, comprising:
providing a solution for fermentation;
adding sugar or fructose to the solution;
inoculating the solution with Bacillus subtilis;
stabilizing the Bacillus subtilis by culturing the Bacillus subtilis before adding green tea to the fermentation solution;
mixing the inoculated solution with green tea leaves, wherein the Bacillus subtilis is in an amount of 10 3 to 10 8 CFU/ml, and the green tea leaves are in an amount of 30-60 wt % based on the total weight of the solution;
fermenting the inoculated solution at a temperature of above 40° C. but less than or equal to about 60° C. for 24 hours to 28 days to provide a fermented green tea; and
administering to the subject an effective amount of a fermented green tea that alleviates cold hands and feet of the subject.

7. A method according to claim 6 , wherein the fermented green tea comprises Sinensis Forma bohea.
