The present invention relates to a culture medium composition for promoting stem cell proliferation comprising plant extracts, and more specifically, to a culture medium composition for promoting stem cell proliferation comprising nine kinds of plant extracts including an arnica flower extract, a gentiana extract, a yarrow extract, a sagebrush extract, a camomile flower stamen, a ginkgo leaf extract, an Asiatic pennywort extract, a Portulaca extract, and a morus bark extract as active components； a manufacturing method of the composition； a cultivating method of a stem cell using the composition； and a composition for improving a skin condition comprising a culture cultivated and acquired by the cultivating method as an active component. Since the composition for cultivating a stem cell, comprising the plant extracts as active components in accordance with the present invention, does not use an expensive animal serum, and thus manufacturing costs can be substantially reduced； and the contamination of an animal material caused by using an animal serum in a culture medium can be prevented to provide a safer stem cell. Also, the culture medium in which the stem cell is cultivated using the composition, comprising the plant extracts as active components in accordance with the present invention, has stem cell proliferation promotion and activation capabilities, and thus can be used as a cosmetic composition which can provide the improvement of a skin condition such as reducing wrinkles on a skin, suppressing the skin aging, improving skin elasticity, wound regeneration, and skin regeneration.본 발명은 식물추출물을 포함하는 줄기세포 증식 촉진용 조성물에 관한 것이다. 보다 상세하게는, 아르니카꽃추출물, 겐티아나추출물, 서양톱풀추출물, 쓴쑥추출물, 캐모마일꽃수, 은행잎추출물, 병풀추출물, 마치현추출물 및 상백피추출물, 상기 9종의 식물추출물을 유효성분으로 포함하는 줄기세포 증식 촉진용 배지 조성물, 상기 조성물의 제조방법, 상기 조성물을 이용한 줄기세포의 배양방법 및 상기 방법에 의해 배양되어 수득된 배양물을 유효성분으로 포함하는 피부 상태 개선용 조성물에 관한 것이다. 본 발명의 식물추출물을 유효성분으로 포함하는 줄기세포 배양용 조성물은 고가의 동물성 혈청을 사용하지 않으므로, 제조비용을 현저히 낮출 수 있고, 동물성 혈청을 배지에 사용함으로써 발생되는 동물성 물질의 오
