Claim Text:
1. A method for producing purified bee venom on a mass scale, comprising: dissolving crude bee venom in water to form a bee venom solution, wherein the crude bee venom is present in the solution in an amount of 0.02-0.1 wt %; filtering the bee venom solution through a cellulose filter paper having a particle size of 20-30 μm under reduced pressure to remove non-water-soluble impurities; applying an absorbent to the filtered bee venom solution at a level of 0.1 to 10 g per liter of the bee venom solution to form a mixture, wherein the absorbent is a primary and secondary amine (PSA); removing the absorbent by filtering the mixture through a cellulose filter paper having a particle size of 0.45-0.8 μm, followed by filtering the mixture again through a cellulose filter paper having a particle size of 0.2 μm under vacuum, to produce a purified bee venom solution free of water-soluble foreign impurities; and lyophilizing the purified bee venom solution at −20° C. or less to obtain said purified bee venom, wherein the purified bee venom is 99% pure.
