Problems solved by technology

[0005] 1) Yujin injection simply extracts the volatile oil components of Houttuynia cordata and honeysuckle, and discards a large number of other ingredients with antibacterial and anti-inflammatory activities, such as the active ingredient chlorogenic acid in honeysuckle, which is obviously unreasonable;
[0006] 2) The injection made of volatile oil is not easy to be mixed with other preparations clinically, causing great inconvenience;
[0007] 3) Unavoidable shortcomings such as unfavorable storage and transportation of injections, and unsuitable use under some special conditions (such as severe cold regions) affect the further promotion and use of Yujin injection preparations
Although the freeze-dried powder preparation of Houttuynia cordata and honeysuckle is described in the patent application No. CN200410080243.7 patent application "A kind of freeze-dried powder injection of fish gold and its preparation method", the mode of taking combined treatment cannot be different according to the characteristics of each medicinal material. Targeted extraction and purification, and the method cannot clarify the content of index substances in the preparation, which increases the risk of drug safety and controllability
