Description

Osmanthus ebony tea and preparation method thereof

technical field

The invention relates to the technical field of teabag (beverage) processing, in particular to an osmanthus fragrans and black medicine drink and a production process thereof.

Background technique

Wuyao is a traditional Chinese medicinal material with a wide range of pharmacological activities. Traditional Chinese medicine believes that anyone who suffers from chest and abdomen discomfort due to qi inversion can use black medicine to relieve it. Studies have shown that its active ingredient alkaloid has anti-inflammatory, anti-oxidation and anti-cancer effects, making it have broad development prospects. The production of ebony tea beverages on the market generally directly makes tea bags from wu yao leaves, roses or cloves, etc. and brews them.

Therefore, it is necessary to improve the prior art.
