Powder of P. buxifolius leaves significantly (p<0.05) decreased fat, cholesterol and low density lipoprotein yolk egg quail but significantly increased High Density Lipoprotein (HDL) at measurement 45, 60 and 75 days old. Fed of 4.0 and 6.0% leaves of P. buxifolius powder significantly (p<0.05) increased the expression of interleukin-S and lymphocytes but significantly (p<0.05) decreased nitric oxide synthase (iNOS), leukocytes and monocytes even undetectable levels.
