The present invention relates to a manufacturing method for anti-virus chlorella extract and a product thereof. The method includes the following steps: (a) putting chlorellas into water, (b) immersing the chlorellas at low temperature, (c) pouring hot water into the liquid, (d) cooling the liquid after extracting, (e) removing residue from the liquid after a centrifugal process, and (f) condensing the liquid. After the above method, chlorella essence powder can be further produced by using a drying method. In addition, after the above steps (a) to (f), chlorella essence liquid can be produced by removing macromolecular proteins by using centrifugation method, and then performing high temperature steam sterilizing. The product is capable of enhancing cell regeneration ability, strengthening the immune system function, and preventing and/or curing infections of enterovirus, Japanese encephalitis virus, and Dengue virus, so as to achieve the efficacy of reducing virus infectivity.本發明係指一種抗病毒綠藻萃取物之製造方法及其製品,該方法包含以下步驟:(a)將綠藻加入水中後,(b)經低溫浸泡後,(c)注入熱水,(d)經萃取後冷卻,(e)離心後去渣,以及(f)濃縮等方法後,進一步處理,一者以乾燥法製成綠藻精粉,另者,循上述(a)至(f)步驟後,以離心方法去除大分子蛋白質後,經以高溫蒸氣滅菌後製成綠藻精液體。該等製品具有促使細胞再生能力、加強免疫系統功能,且具有預防及/或治療腸病毒及日本腦炎病毒、登革病毒之感染,達降低病毒感染力價之功效。
