Abstract

The invention relates to a composition. The composition includes ginsenoside Rk1, ginsenoside Rg5, ginsenoside CK and a total ginsenoside ginseng root extract product; and the composition is an interleukin (IL)-6 conditioning agent. Applications of the composition in the preparation of drugs are also related.

Description

technical field [0001] The invention relates to a composition comprising the following components: ginsenoside Rk1, ginsenoside Rg5, ginsenoside CK, and total ginsenoside extract, wherein the composition is an interleukin (IL)-6 regulator. The invention also relates to the use of the composition in the preparation of medicaments. Background technique [0002] Interleukin-6 (IL-6) is a cytokine composed of 184 amino acids with a molecular weight of 21-26 kDa. Interleukin-6 is produced by various cells such as lymphocytes, monocytes, macrophages, vascular endothelial cells and tumor cells under the stimulation of various stimulating substances. Its biological properties include inducing B cells to produce antibodies, activating T cells, and accelerating the synthesis of other acute inflammatory proteins. On the other hand, the overexpression of interleukin-6 can lead to the occurrence of various inflammation-related diseases, including thrombocytosis, myeloma, Castleman's di...
