Pharmaceutical composition against type I allergy and the preparation thereof

An extract for treating Type I Allergy obtained by the process comprising:

• (a) Infiltrating 30˜60 weight parts of Fructus Jujubae into a warm alcohol solution while keeping its pH value between 3.6˜3.8 to obtain a Fructus Jujubae and alcohol mixture, extracting and filtering the Fructus Jujubae and alcohol mixture to obtain an extract solution, treating said extract solution by fractional absorption using a macroporous resin in order to eliminate sugar, and obtaining a dry extract of Fructus Jujubae by concentration;
• (b) Squeezing 6˜12 weight parts of ginger to obtain a ginger liquid and filtering the ginger liquid with a plate frame filter to obtain an extractive liquid of ginger;
• (c) Infiltrating 4˜8 weight parts of green tea into boiled water to obtain a green tea liquid and filtering the green tea liquid with a plate frame filter to obtain an extract liquid of green tea;
• (d) Mixing and decocting 12˜55 weight parts of Radix Astragali, 8˜15 weight parts of Radix glycyrrhizae and 6˜12 weight parts of Ramulus cinnamomi together to obtain a Radix Astragali, Radix glycyrrhizae and Ramulus cinnamomi mixture, filtering the Radix Astragali, Radix glycyrrhizae and Ramulus cinnamomi mixture to obtain a mixed extract liquid;
• (e) Mixing and concentrating the mixed extract liquid obtained in step (d) with the extract liquid of green tea, then adding the extract liquid of ginger and concentrating the mixture until the mixture reaches a relative density of 1.1˜1.4/80 at about 85° C. to obtain a thick paste and concentrating said paste into a dry extract;
• and
• (f) Grinding and mixing the dry extract obtained in step (e) with the dry extract of Fructus Jujubae obtained in step (a) to obtain an extract.
