摘要

The present invention relates to a method for removing dermatitis-induced toxic substances from Rhus verniciflua, and to a method for preparing the same, comprising the steps of: (S1) first drying rhus verniciflua in a cool shade for 4 to 6 months; (S2) finely crushing the primary dried Rhus verniciflua and then secondary drying in sunlight for 5 to 10 days; (S3) tertiary drying of the secondary dried Rhus verniciflua at a temperature of 60 to 80 DEG C for 40 to 60 hours by using a herbal drier; (S4) drying the dried tree in a cool shade for 3 to 7 days and then drying it at a temperature of 60 to 80 DEG C using a herb drier for 40 to 60 hours to obtain a dried tree; And (S5) 15 to 25 parts by weight of lacquer dried in step (S3) and 0.1 to 0.5 part by weight of dried coconut tree in step (S4) are added to 100 parts by weight of water, And extracting the extract under the condition of 1.0 to 1.5 atm for 40 to 60 hours according to the method of the present invention for extracting the extract of Rhus verniciflua, the content of urushiol, which is a dermatitis inducing substance contained in Rhus verniciflua, is minimized, The ingredients can be kept intact. Therefore, it is expected that it can be used as a food additive of lacquer tree without any rejection and allergic reaction since it can prevent the occurrence of dermatitis due to toxic substances in the production of food using lacquer tree.
