Benefits of technology

"The present invention provides a composition for treating and preventing pollinosis, which is caused by allergic hypersensitivity against pollens. The composition contains an extract from Sasa albo-marginata (Bambooseae Sasa) in an amount ranging from 1 to 10% by mass. The extract has a high effect in treating and preventing pollinosis, which is accompanied by symptoms such as conjunctivitis, rhinitis, and bronchial asthma. The invention helps alleviate the symptoms of pollinosis and provides a natural solution for those who are allergic to pollens."

Problems solved by technology

In respect of pollinosis, a steroidal drug has been used for alleviating the related symptoms, but the symptoms have never been alleviated in a large number of patients even if such a steroidal drug is administered to these patients.

Preparation of Sasa albo-marginata Extract

[0060] Dried leaves of the Sasa albo-marginata collected in TESHIO Mountains in Hokkaido Japan in September were introduced into a pressurized hot water extraction tank, treated at 125° C. for 10 minutes in the tank, the hot water was cooled down to about 80° C. by the action of a cooling water and then the resulting extract was separated from the moisture-containing solid content using a screw-press in such a manner that the moisture content of the latter was controlled to a level of about 50% by mass. Then the solid contents having a moisture content of about 50% by mass were introduced into an autoclave and heat-treated under pressure at 180° C. for 10 minutes using saturated steam. The moisture-containing solid contents thus treated were again introduced into a pressurized hot water-extraction tank and treated at 110° C. for 5 minutes to thus obtain an extract. The first and second extracts were combined together, filtered through a dia...

reference example 2

[0062] The commercially available Sasa albo-marginata extract (the extract derived from Bambuseae Sasa; available from HOUOUDOU Co., Ltd.) was inspected for the components thereof and as a result, the extract included the following components: Water: 59.5% by mass; Proteins: 8.6% by mass; Lipid: 0.6% by mass; Minerals: 9.0% by mass; Carbohydrates: 19.8% by mass; and Tannin: 2.5% by mass.

[0063] The components listed in the following Table 2 were admixed together in amounts (% by mass) likewise specified in Table 2, introduced into a heating and mixing kettle equipped with a stirring blade and an emulsification apparatus and then mixed therein with stirring at 80° C. for 2 hours to thus give a cream composition for treating and / or preventing pollinosis according to the present invention. The added amounts of a Sasa albo-marginata extract having a solid content of 8% by mass (a product obtained by diluting the Sasa albo-marginata extract having a solid content of 50% by mass and prepared in Reference Example 1) were 12.5, 25, 37.5 and 75% by mass respectively (therefore, the contents of the extract as expressed in terms of the solid content thereof were 1, 2, 3 and 6% by mass; and sulfur contents of these samples were 7.7 mg, 15.4 mg, 23.1 mg and 46.2 mg per 100 g of the composition, respectively).

Abstract

The present invention provides a composition for treating and / or preventing pollinosis which comprises an extract from Sasa albo-marginata in an amount ranging from 1 to 10% by mass as expressed in terms of the solid content of the extract. The composition of the present invention comprises a Sasa albo-marginata extract in a concentration considerably higher than that conventionally used and accordingly, it shows a high effect of treating and / or preventing various symptoms associated with serious pollinosis, which has been quite difficult to treat and / or prevent with the conventional anti-histamic agents or steroidal drugs, without accompanying any side-effect.

Description

TECHNICAL FIELD [0001] The present invention relates to a composition for treating and / or preventing pollinosis, which comprises an extract from Sasa albo-marginata (Bambooseae Sasa) as an effective component. BACKGROUND ART [0002] Recently, there have rapidly been increased the number of patients suffering from allergic symptoms (hereunder referred to as “pollinosis”) accompanied by, for instance, conjunctivitis (itching and congestion of eyes), rhinitis (sneezing, snivel and nasal congestion) and bronchial asthma, which are caused due to the allergic hypersensitivity against pollens of, for instance, hinoki (white cedar), sugi (Japanese cedar) and ragweed (Ambrosia artemisiifolia), and dead bodies of, for instance, ticks or mites. In respect of pollinosis, a steroidal drug has been used for alleviating the related symptoms, but the symptoms have never been alleviated in a large number of patients even if such a steroidal drug is administered to these patients. Accordingly, there h...
