Description

Health tea for promoting digestion and preventing halitosis as well as preparation method and application thereof

Technical Field

The invention relates to the field of tea beverages, and particularly relates to health-care tea for promoting digestion and preventing halitosis, and a preparation method and application thereof.

Background

Halitosis is one of the causes influencing social interaction and causing mental disorder, and serious halitosis often causes distress to patients. WHO has documented halitosis as a disease, which is often manifested as a pronounced odor during breathing, difficulty in removing symptoms during brushing and rinsing, difficulty in masking by using a cleanser, and an odor originating in the oral cavity and the interior of the body.

The main substances causing halitosis are volatile sulfides, and hydrogen sulfide and methyl mercaptan are the two most main components. The sulfide is secreted by amino acid, protein and peptone in the interstitial space of the oral cavity rich in microorganisms.

The halitosis caused by functional dyspepsia is an important one of the causes, and the symptoms mainly include upper abdominal pain, upper abdominal distension, early satiety, belching, inappetence, nausea, vomiting and other uncomfortable symptoms.

There is no radical cure method for dyspepsia clinically, and most of the medicines are medicines for relieving or controlling symptoms, and the commonly used medicines include acid-inhibiting medicines, gastric motility-promoting medicines, mucosa-protecting medicines, psychology-and mental regulation medicines, etc., but most of the medicines have strong irritation, and have the problems of easy repetition and easy operation after stopping the medicine.

Meanwhile, for the treatment of halitosis caused by dyspepsia, at present, methods such as tooth brushing, mouth rinsing or using a breath freshener are mainly adopted for relieving, but the currently used medicines can only achieve the effect of treating symptoms of halitosis, have short drug effect period and cannot achieve the effect of thorough treatment.

In view of the above, the present invention is particularly proposed.
