Abstract: Pharmaceutical composition and food comprising edible carboxylic acid and/or its acidic salt and optionally caffeine, crude drug and pharmaceutical acceptable carrier are disclosed. The invention also discloses the use and method of composition or food. The composition or food of the present invention can prevent, treat or relief allergy, ache, cold, viral infection, thrombus or clotting, inflammation, cancer, intoxication, memory decay, caffeine dependence. The invention also relates to feedstuff for animals.

Abstract: This invention relates to a drug containing edible acid and/or acidic salt as active agent to treat and alleviate hypersensitivity diseases by lowering the humor pH and method; to improve individual hypersensitivity diseases by uses of health care food, which are made from said edible acid and/or acidic salt, or the acidic fruits containing thereof, or their products; foods lowering the risk of hypersensitivity and their preparation methods; drug to lower the humor acidity and to treat or alleviate disease caused by insects bite toxin; that also to be drug for cold or virus infection; drug for inflammation; drug for analgesic; and drug for thrombus disease; method lowers the hypersensitivity risk of clothing or grove and their products.

Abstract: This invention relates to areca food additives, especially, to additives for areca quids and foods containing areca component, and their preparation methods. High alkaline lime always exists in conventional areca food additive. Many problems consequently result such as oral cancer and the polluting of the environment by the spitting of a bright red liquid. A series of eatable neutral calcium salts of organic acid and compounds containing at least one of the following functional groups selected from the group consisting of --NH2, .dbd.NH, .tbd.N, --NH--, --CONH--, --HCO--, --CO--, --COOR--, --S--, and their salts were invented to replace lime. The taste of astringent and harms caused by the polyphenolic compounds of areca quid could be completely improved. The disease of quid chewer would be decreased and the problem of environmental pollution would be improved.

Abstract: Disclosed is a self-lubricating composite material prepared from polymers, used for the fabrication of bearing members. The composite material is characterized by the fillers or solid lubricants contained therein which have been treated with titanates or silane compounds and by the liquid lubricant contained therein which include polar compounds. Bearing members made by this self-lubricating composite material have a lower friction coefficient than commercial self-lubricating bearing members, can use thermoset plastics as a matrix and can be made into colored products.
