Preparation method of cold heat-clearing tablet

Abstract

The invention discloses a preparation method of a cold heat-clearing tablet. The preparation method comprises the following steps: (1) weighing raw materials; (2) preparing three traditional Chinese medicines of schizonepeta spikes, mint and perilla leaves, adding water which is 8-12 times of mass of weights of the traditional Chinese medicines, distilling to extract volatile oil for 1.0-2.0 hours, and collecting a distilled water solution; adding water into decoction residues and other medicines, and carrying out decoction twice, namely adding water which is 8-12 times of mass of the all traditional Chinese medicines, carrying out decoction for 1.0-2.0 hours, and filtering, so as to obtain a filtrate; adding water which is 6-10 times of mass of the all traditional Chinese medicines into the filtered decoction residues, carrying out decoction for 1.0-2.0 hours, and filtering, so as to obtain a filtrate; combining two filtrates with the distilled solution; and (3) combining decoction solutions, carrying out reduced pressure concentration, adding auxiliary materials, carrying out granulation, spraying the volatile oil obtained in the step (2), and carrying out tabletting, so as to form a base tablet, or a coated film or a sugar coating, namely the cold heat-clearing tablet. The preparation method has the beneficial effects that the extraction temperature is low, the energy consumption is low, the extraction time is short, the loss of temperature-sensitive components is low, and the recovery rate of effective components is high.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine, in particular to a preparation method of Ganmao Qingre Tablet. Background technique [0002] Flu is a common disease affecting the health of patients, which can lead to poor mental state of patients, and has a great impact on life and work. Cold is also a kind of acute infectious rhinitis, commonly known as "cold". It is caused by respiratory viruses, among which coronavirus and rhinovirus are the main pathogenic viruses. The virus is excreted and spread from respiratory secretions. When the body's resistance decreases, such as cold, malnutrition, excessive fatigue, excessive smoking and alcohol, systemic diseases, and chronic diseases of the nose itself that affect the smoothness of the respiratory tract, infections are easily induced. At present, more and more people choose to use traditional Chinese medicine because of the small side effects of traditional Chinese medici...

Problems solved by technology

Traditional Chinese medicine uses the decoction method to extract the active ingredients of medicinal materials. In the preparation process of traditional Chinese medicine, there are generally disadvantages such as long extraction time, high extraction temperature, high energy consumption, easy loss of heat-sensitive ingredients, low recovery rate of active ingredients, and troublesome post-processing.
