This study was designed to investigate the effect of Korean traditional tea materials on lead (Pb) accumulation and histological changes in Pb-administered rats. Male rats were divided into six groups: a normal, Pb, and Pb-water extract of Korean traditional tea materials (green tea: GT, persimmon leaf: PL, safflower seed: SS, Eucommia ulmoides: EU) groups. Pb (25 mg/kg BW) was orally administered once a day for 4 weeks. The extract of GT, PL, SS, and EU were administered based on 1.26 g of raw traditional tea materials/kg BW/day. Pb contents of serum and liver were significantly higher in the Pb group than in the normal group. However the water extracts of GT, PL, SS, and EU administration lowered Pb contents of serum and liver in the Pb-administered rats, respectively.
