NATURAL CHINESE HERBAL COMPOSITION FIELD OF INVENTION

The invention relates to a natural composition for external use on face and body to rejuvenate the skin. In particular, the composition contains a mixture of herbs that can be used for skin whitening, skin tightening, pore refining and alleviating skin problems such as acne, pigmentation and wrinkles for all types of skin.

BACKGROUND OF THE INVENTION

Chinese herbs are basically plant elements that can be used as major ingredients in a composition for external or internal use owing to their healing properties. Some of the commonly used herbs are Ginseng, wolfberry, Angelica Sinensis, astragalus, atractylodes, bupleurum, licorice, peonym, rhubarb and salvia. There are some prior arts related to the composition of herbs in skin improvement. China Patent No. CN102188358(A) discloses a Chinese medicine cosmetic containing egg white and a preparation method thereof. It is characterized in that the egg white is essentially mixed with Chinese medicine extracts comprising Radix Angelicae, Bletilla Striata and other Chinese medicine extracts as a main ingredient. The Chinese medicine extracts are supercritically extracted and mixed with a certain amount of egg white, followed by homogenisation and centrifugation to obtain an aqueous layer. Nevertheless, the technique imparts chemical into the composition that may essentially cause skin irritation to users. Another China Patent No. CN101590197(A) discloses a pure Chinese medicinal whitening anti-freckle agent comprises Glycyrrhiza uralensis, Tribulus terrestris, Radix Angelicae, Rhizoma Atractylodis and Bighead Atractylodes rhizome. However, the ingredients are soaked in ethanol and extracted prior to usage. Similarly, it involves chemicals in preparation of the composition. Furthermore, it does not possess anti-inflammatory effect that is able to sooth acne problem. Another China Patent No. CN101756876(A) discloses a freckle removing facial mask comprising Angelica Sinensis, Angelicae Dahuricae, Bletilla Striata and Glycyrrhiza uralensis. However, the facial mask is lack of specific active ingredients which are effective in reducing redness which is caused by acne or eczema.

Another China Patent No. CN102188562(A) discloses a formula of Chinese medicine for removing scars of acnes and the preparation method thereof. The formula comprising Poria Cocos, pearl powder and Angelica Dahurica. Nevertheless, this formula is only limited to lightening of scars caused by acne.

The mask compositions in the market generally comprising mixtures of plant extracts with additives such as emulsifiers and preservatives. These additives may not be suitable for users with sensitive skin. Hence, it is desirable for the industry to invent a mask composition containing only natural ingredients that is suitable for all skin types. On top of skin whitening and. pore refining, a mask composition to alleviate skin conditions such as acne, pigmentation and wrinkles for all types of skin is highly desirable. SUMMARY OF INVENTION

The Angelica sp. used is particularly preferred to possess antioxidative, anti- inflammatory and immunomodulatory activities. The herbs derived from Angelicae sp. are Angelicae sinensis, Angelica dahuricae or a combination thereof. Preferably, the Angelicae sinensis is present in an amount of 7 to 23 wt% of the composition. Further, the Angelicae dahurica is present in an amount of 3 to 14 wt% of the composition. In particular, the Angelicae sp. employed can be derived from roots of Angelicae sp. plant.

In the preferred embodiment, the Angelicae sp. employed is able to reduce skin problems caused by pigmentation. Spots and freckles can be lighten through topical application of the composition in the present invention. The Angelica sp. employed are known in the prior arts to be able to attenuate melanin synthesis. There is prior art that discloses the use of ethanol extracts from Angelicae Dahuricae to inhibit melanogenesis that forms pigment on the skin. Besides, another prior art has disclosed the use of hexane and dichloromethane extracts of the Angelicae sinensis to treat hyperpigmentation which causes melanogenesis. Nevertheless, the composition in the present invention is substantially free of chemical in contrast to the prior arts. Further, the inventor of the present invention found that Angelica sinensis in the composition of the present invention is able to lighten pigmentation or spots without causing toxicity and skin irritation. Common chemical treatment to remove pigments utilises bleaching agents which contains hydroquinone and kojic acid. Improper usage of such bleaching agents may cause abnormal lightening on specific areas of the skin. Moreover, skin irritations including mild itching and stinging may occur during the chemical treatment. The Angelica dahurica employed can also be used in the composition to impart healthy glow on the skin. In the preferred embodiment, the Angelica dahurica in the composition is able to relax tired and irritated skin. Further, it is able to tone all types of skin to achieve a pore refining effect. Another major herbs employed in the composition are derived from roots of Paeoniae sp. plant. The Paeonia sp. is commonly called white peony that refers to the colour of the processed root. Though less common, the herbs derived from flowers and seeds of Paeoniae sp. can also be used. In the preferred embodiment, the herbs derived from the Paeoniae sp. are present in an amount of 3 to 13 wt% of the composition.

In the preferred embodiment, glycosides, flavonoids, proanthocyanidins, tannins, terpenoids, triterpenoids and complex polysaccharides can be found in the Paeoniae sp.. Hence, the Paeoniae sp. contains anti- microbial, anti- inflammatory and astringent properties. Paeoniae sp. is preferably used in the composition to reduce redness on the skin caused by acne or eczema. Further, the astringent properties of the Paeoniae sp. can be essentially used for mild coagulation of skin proteins to protect or strengthen the skin from external stimutii.

Further, minor skin irritations such as those resulting from superficial cuts, allergies, insect bites or f ngal infections can be soothen by topical application of the composition comprising the Paeoniae sp.. In the preferred embodiment, the Paeoniae sp. can be employed for oil balancing on the skin. This renders the composition to be suitable even for oily skin. Further, it also functions in the composition to sooth cracked or chapped skin. Moreover, the composition comprising the Paeoniae sp. can be used for pore refining.

Preferably, Atractylodes macrocephalae can be utilised. The rhizomes or roots of ^' Atractylodis sp. plant can be used. Preferably, the rhizomes are employed. The Atractylodes sp. employed essentially contains essential oil, glucoside and inulin. The Atractylodes sp. can be used to increase significant anti-inflammatory effect in the composition. Further, it can also impart detoxifying or deep cleansing function to the composition. Hence, toxins trapped in the skin that substantially causes pimples, acnes and whiteheads can be removed. Consequently, skin problems associated with acne or eczema can be soothen.

Another herb derived from Bletilla sp. is present in an amount of 3 to 20 wt% of the composition. In particular, the herbs from Bletilla sp. can be derived from tubers of Bletilla sp. plant. The Bletilla sp. can be Bletilla striata, Bletilla sinensis or Bletilla ochracae. Preferably, Bletilla striata is employed. Bletilla Striata is preferably used in the composition to reduce redness and sooth agitated skin. It is able to facilitate closure of wound on the skin owing to its haemostatic characteristic. Hence, wounds or scars that are caused by outbreak of acnes can be gradually lightened. Nevertheless, cracked or chapped skin caused by dehydration or physical trauma can also be reduced with the presence of Bletilla Striata in the composition.
