Embodiment 1

[0021] After the yellow gardenia leaves are washed and dried, they are immersed in 85% ethanol solution at a ratio of 1:10 for 90 minutes; the above mixture is placed in a water bath and heated under reflux for 3 hours, filtered, and the filtrate is collected. Double the amount of 85% ethanol and repeat the extraction once, and combine the two filtrates; take the above-mentioned filtrate and concentrate it under reduced pressure until there is no alcohol smell. The concentrated solution is adsorbed by AB-8 macroporous resin column, first eluted with distilled water, and then with 65% ethanol Elution, collecting the ethanol eluate, and concentrating under reduced pressure to obtain the yellow gardenia leaf extract.

[0022] Prepare yellow gardenia leaf extract and black tea in a weight ratio of 1:5.

[0023] Pile the black tea evenly on the mat with a thickness of 10cm, and spray the yellow gardenia leaf extract on the black tea evenly in 3 times, cover with cotton and linen cloth a...

Embodiment 2

[0027] After the yellow gardenia leaves are washed and dried, they are immersed in a 75% ethanol solution at a material-to-liquid ratio of 1:10 and soaked for 30 minutes; the above-mentioned mixed solution is heated and refluxed in a water bath for 1.5 hours, filtered, and the filtrate is collected and used for the filter residue. Repeat the extraction with 8 times the amount of 75% ethanol, and combine the two filtrates; take the above filtrate and concentrate it under reduced pressure until there is no alcohol smell.
