Abstract: The present invention discloses a preparation method for extractive of Jinxuan Hemorrhoid Washing Powder botanicals comprises the steps: A, honeysuckle, schizonepeta, and purslane in the prescription of Jinxuan Hemorrhoid Washing Powder are mixed, ground, and passed through a mesh; the medicinal powder obtained from supercritical extraction is soaked in alcohol, then undergoes percolation extraction, and the percolate is collected; B, the alcohol percolate is concentrated, left stand, and suction filtrated to obtain a filtrate; C, the filtrate macroporously adsorpts to a resin column at a flow velocity, is then removed of to impurity by water washing, and undergoes elution with alcohol to obtain an alcohol eluent; D, alcohol is recovered from the eluent, the remaining liquid is concentrated, and the concentrated liquid is dried to obtain the extractive of Jinxuan Hemorrhoid Washing Powder botanicals.

Abstract: Embodiments herein provide a method, system, etc. for a sovereign information sharing service. More specifically, a method for secure distributed query processing comprises storing data tables from at least one data provider in at least one first computer comprising a sovereign server. Next, encrypted input and output of the data tables is performed between the server and a second computer. Following this, join operations are computed, comprising determining whether arbitrary join predicates yield matches within the data tables; and encrypted results of the join operations are output. The method minimizes possible information leakage from interaction between the server and the second computer by making observations and inferences from patterns of the outputting of the encrypted results.
