Abstract

A Chinese medicine for treating upper respiratory tract infection, bronchitis, viral pneumonia, pyrogenic diseas, gynopathic inflammation, etc is prepared from houttuynia and honeysuckle flower through distilling extraction, extracting by water or alcohol, and mixing both extracts together. Its advantage is high curative effect.

Description

technical field [0001] The invention relates to a pharmaceutical preparation and a preparation method thereof, especially a houttuynia cordata and honeysuckle preparation (hereinafter referred to as the fish gold preparation) and a preparation method thereof. Background technique [0002] The components of Houttuynia cordata and honeysuckle have antibacterial, antiviral, antipyretic, anti-inflammatory, and immune-regulating functions. In order to improve its efficacy, people adopt the method of extracting its active ingredients to make a medicament, which is easy to use and has better efficacy. At present, there is Yujin injection in the market. The volatile matter in Houttuynia cordata and honeysuckle is extracted by distillation, and processed into injection. It is clinically used to treat upper respiratory tract infection, bronchitis, Viral pneumonia, suppurative disease, gynecological inflammation, and postoperative fever have a good effect. The patent application numb...
