Abstract:
1. A method for producing an injectable solution, comprising the following steps: a) cutting and drying b) calcination of the dried cut roots obtained in stage (a) at a temperature of 550-600° C., over a period of 3 to 4 hours to produce ash; c) dissolving the ash obtained after calcination in distilled water to produce a solution, d) filtering the obtained solution under vacuum, followed by additional filtration through Sempore filters and then through Millipore filters to produce a filtrate; e) drying the filtrate by boiling evaporation to produce a liquid having a high viscosity; and then further drying a thin layer of the high viscosity liquid at a temperature of 200-250° C., over a period of 5-15 minutes until a white powder is obtained; and f) dissolving the white powder in distilled water or a saline solution to produce injectable solution.
