Abstract

The invention relates to a compound preparation of magnolia bark and cnidium fruit hypercritical carbon dioxide extract, which comprises magnolia bark extract, cnidium fruit extract and medicinal auxiliary materials. The invention provides a safe, controllable, stabilized, and effective Chinese preparation for treating asthma.

Description

1. Technical field: [0001] The invention relates to the field of medical preparation of traditional Chinese medicines, in particular to a compound preparation of supercritical carbon dioxide extracts of Magnolia officinalis and Fructus Cnidii. 2. Background technology: [0002] Asthma is one of the common chronic diseases in the world. There are about 150 million asthmatics in the world. In the past two decades, the incidence rate in the world has been gradually increasing. It is of great significance to study its treatment. At present, Drugs for treating asthma include: 1. Adrenergic receptor agonists; 2. Antiallergic drugs; 3. Theophylline drugs; 4. Glucocorticoids. But above-mentioned medicine all has certain untoward reaction, and long-term use chemical medicine, can produce tolerance sometimes and make curative effect decline, sometimes can be difficult to be effective because of the asthma of different etiology. Therefore, the research and development of safe, control...
