A compound fat-reducing tea was mainly made from Hawthorn,Lotus leaf and Oolong tea,and its anti-obesity action was studied on model rats with nutritional obesity.The experimental results show,comparing with obese control group,the body weight level in high dosage group of feeding extracting liquid of the tea decreased significantly(P<0 01),the body weight level in low dosage group decreased obviously(P<0 05);the fat index and lipocyte volume level in high and low dosage group reduced significantly(P<0 01);the TC level in high and low dosage group lowered apparently(P<0 05),the TG level in high dosage group also lowered obviously(P<0 05).The acute toxicity test indicated that its LD 50 was 100 g/kg.These results indicated that the compound tea is effective in fat-reducing,and with little or no toxicity.
