TECHNICAL FIELD The present invention relates to a cosmetic composition for improving atopic dermatitis,

The present invention relates to a cosmetic composition for improving atopic dermatitis, which contains an extract of Radix japonicum.

Atopy occurs mainly in infancy and is called as fever, and it occurs mainly as the content of ceramides in the stratum corneum is decreased.

The cause of atopic dermatitis has not been clarified yet, but it is presumed that it is caused by the disturbance of the immune system.

In general, atopic dermatitis is dry due to a decrease in the water retention function of the stratum corneum, and skin barrier function is lowered, so that skin allergy can easily occur, so that it is prone to be pruritic, repeatedly recurring, do.

In many cases, it is exacerbated repeatedly at intervals of 1 to 2 weeks. If not properly managed, it progresses to subacute lesions of erythematous eruption with exudation, chronic lesions of thickening skin like skin.

The cause of atopic skin is divided into two main causes. One is genetic cause, and it is inherently deficient in gamma-linoleic acid (GLA) This is caused by the weak and easily disappearing of moisture on the surface of the skin. Other causes are environmental factors, such as dry living environment, reactive oxygen species, bacteria, viruses, fungi, etc. [Dermatology, Korean Society of Dermatology Editorial Committee,

Atopic dermatitis causes mast cells to release an allergic reaction inducer such as histamine in the intracellular granules, indicating degranulation [Gao ZG, et al., Biochem Pharmacol. 2009. Nov 5]. In addition, atopic dermatitis has been reported to be associated with allergic rhinitis and asthma, and thus it is highly likely to be an allergic disease [de Meer G, et al., Pediatr Allergy Immunol. 2009. Nov 13].

A composition comprising as a main ingredient various natural substances for improving atopic dermatitis has been disclosed. In Korean Patent Publication No. 10-1418916, a composition for improving atopic dermatitis comprising an extract of Chrysantida or an active fraction isolated therefrom by chromatography as an active ingredient is disclosed Korean Patent Publication No. 10-1382115 discloses a food composition containing ginseng fruit extract as an active ingredient and improving atopic dermatitis or dryness. Korean Patent Publication No. 10-1083347 discloses a food composition containing a moss extract as an active ingredient A pharmaceutical composition for improving or treating atopic dermatitis is disclosed.

On the other hand, Tagetes minuta (Tagetes minuta) is an annual plant of Asteraceae called garbage grass and widely distributed in the wild.

In Korea, some plants are grown for the purpose of ornamental use, but in foreign countries, they have been used for fragrance, coloring and medicinal resources in addition to ornamental use. It is commercially grown in South America, India and southern Europe.

For example, in southern India, Europe, South America, and the United States, private prescriptions are used to control the infusion of raw water from aquatic plants. It has been shown to be effective for the treatment of liver disorders, intestinal diseases, diarrhea, abdominal pain, headache, pneumonia, cough and fungal skin diseases as well as anticonvulsant, anti-inflammatory, antibacterial and antimicrobial effects [Radzen et al , ≪ / RTI > Parfmer und Kosmetik, 67, 52-55 (1986); Zygadlo et al., Lag.
