Abstract

PROBLEM TO BE SOLVED: To provide a promoter for vascular endothelial growth factor(VEGF) production having excellent neovascularization inducing effects. SOLUTION: This promoter for the VEGF production is obtained by including one or more kinds selected from an extract from Paeonia lactiflora Pall. and its allied species, an extract from a plant belonging to the genus Tilia, respective extracts from Equisetum arvense L., Mentha arvensis L. var. piperascens Malin., Mentha piperita L. and Mentha viridis L. and an extract from a leaf of a plant belonging to the genus Citrus in a base or a carrier.

[0004] However, the above-mentioned components and the like do not always act specifically at a wound site or a hair follicle, and there is a problem that an expected action and effect are not sufficiently obtained or some of them cause undesirable side effects. Was. [0005] By the way, it has been suggested that angiogenesis is induced in the wound healing process and around the hair follicle, and as a result, the wound healing and the transition of the hair follicle to the anagen phase may be promoted. In recent years, VEGF has been found as a factor inducing such angiogenesis. [0006] Therefore, in the present invention, VEGF having an excellent angiogenesis-inducing effect around a wound site or around a hair follicle, which can be particularly effectively applied to a wound healing agent and a hair growth / hair restoration agent. The aim was to obtain a production promoter. [0007] As a result of various studies to solve the above-mentioned problems, Paeonia lactiflora Pa

In the present invention, these leaves are used. The above-mentioned plant may be subjected to extraction as it is, but in consideration of the extraction efficiency, it is preferable to perform extraction after performing processing such as shredding, drying, and pulverization. The extraction is performed by immersion in an extraction solvent. Stirring may be performed to increase the extraction efficiency, or homogenization may be performed in an extraction solvent. It is appropriate to set the extraction temperature at a temperature of about 5 ° C. to the boiling point of the extraction solvent or lower. Although the extraction time varies depending on the type of the extraction solvent and the extraction temperature, it is appropriate to be about 4 hours to 14 days. As an extraction solvent, in addition to water, methanol,
