The present invention relates to a manufacturing method for a natural antibiotic and a preservative using silver and lacquer sap compositions and use thereof. The manufacturing method for a natural antibiotic and a preservative removes toxicity from lacquer sap (oriental lacquer) which has potent toxicity, is poorly dried and is poorly dissolved in water and makes the lacquer sap (oriental lacquer) dissolve easily in water and be dried easily by removing toxicity from the lacquer sap (oriental lacquer) which is poorly dried and manufactures a natural antibiotic by ionizing the lacquer sap with silver (Ag+) by making the silver (Ag+) into small grains with a nano-processing technique and manufacturing nanosilver lacquer sap compositions. The present invention is characterized by a method using the natural antibiotic (oriental lacquer) or nanosilver lacquer sap compositions as a natural antibiotic by adding the natural antibiotic (oriental lacquer) or nanosilver lacquer sap compositions to foods and the like, and a method dipping lacquer compositions in old temples and old books by using the lacquer compositions in tree preservatives, paper preservatives and the like. natural antibiotic, lacquer sap (oriental lacquer), and nanosilveCOPYRIGHT KIPO 2014은(銀)과 옻진액 조성물을 이용한 천연 항생제 및 방부제 제조방법 및 그 용도에 관한 것이다독성이 매우 강하고 건조가 잘 되지 않고 물에 용해 되지 않는 옻진액(칠액)을 독성을 제거 하고 건조가 잘 되지 않는 옻진액(칠액)을 독성을 제거하고 건조가 잘되고 ㅁ물에 잘 용해가 되게 한 다음 은(Ag+)을 나노기술로 소립하여 상기 옻진액에 이온화 시켜 은나노 옻조성물을 제조 하여 천연 항생제를 제조하고 또한 옻진액(칠액) 또는 옻과은나노 조성물을 식품사료 등에 첨가하여 천연방부제 및 천연항생제로 사용 하는 방법 또한 상기 옻조성물을 나무 방부제, 종이방부제 등에 사용하여 고사찰이나, 고서적등에 침지시켜 사용하는 방법이 특징이다.<색인어>천연항생제, 옻진액(칠액),은나노
