This study made an economic evaluation of duck using Houttuynia cordata (H. cordata) powder as feed additives after 6 weeks. A total of 300 ducks (Pekins) were randomly assigned to one of the three treatments (0%, 0.5% and 1% H. cordata powder), with 5 replicates of 20 ducks each. After 6-week feeding trial, an economic improvement in all the treatments was found in following order: T2 (1% H. cordata powder) > T1 (0.5% H. cordata powder) > control. The results suggested that the addition of H. cordata powder to duck diets provided significantly greater economic benefits, indicating sustainable environmental management of the duck industry.

The antilipidperoxidative and hepatopreventive effects of Houttuynia cordata extract(HCE) were investigated at the level of liver homogenates and serum of SD rats intoxicated EtOH(3g/kg for 3days). We measured MDA(malondialdehyde) in the live. homogenate, AST(1-aspartate-2-oxoglutarate aminotransferase) and ALT( 1-alanine-2-oxoglutarate aminotransferse) in the serum. The analysis of the measurement indicated that HCE reduced MDA, ALT and AST significantly and their reduction was in relation to dose dependence. In rat liver homogenate intoxicated with EtOH, HCE treatment group inhibited lipidperoxidation by 50-75%. In rat serum intoxicated EtOH, HCE inhibited AST and ALT by 40-70%.

Objectives : Since cosmetics have been one of the help of life, unlike medicine, natural products have been used for cosmetics, generally giving the image of safety and relief compared to synthetic products. Among them, Houttuynia cordata has been known as a useful herbal medicine with antibiotic, anti-inflammatory and anti-oxidative activities. In this study, we were to use Houttuynia cordata extract on formulation of cosmetic emulsions. Methods : The effects of Houttuynia cordata extract on emulsion stability and viscoelastic properties of emulsion were measured using turbiscan and rheometer. And we assessed the anti-oxidative and antibiotic activities of Houttuynia cordata extract. Results : 1. The results of this investigation for emulsion stability showed that the stability emulsion containing Houttuynia cordata extract was decreased depending on concentration of Houttuynia cordata extract. 2. Super oxide dismutase activity was strongly dependents on concentration of Houttuynia cordata extract. 3. Houttuynia cordata extract showed good anti-microbial activity against Staphylococcus aureus. Conclusions : Houttuynia cordata extract can be effectively used in cosmetic emulsions when the relation between natural product extracts and formulation of cosmetics is elucidated.

Anti-microbiological effects of xanthorrhizol, ie., extract from curcuma xanthorrhiza and extract from houttuynia cordata Thunb. against influenza virus and E. coli O157 were tested. From the influenza experiments, the effects were shown above 93 % in case of houttuynia cordata Thunb. extract, however, the effects was not shown in case of xanthorrhizol. The effects were sustained in mixtures of houttuynia cordata Thunb. and curcuma xanthorrhiza extracts. We also tested the anti-microbiological effects of hand sanitizer containing houttuynia cordata Thunb. and xanthorrhizol. The effect of hand sanitizer containing 2,000 ppm of xanthorrhizol and 500 ppm of houttuynia cordata Thunb. extract was better than that of commercialized foreign product.

The anti-hyperlipidemic effect of Houttuynia cordata was assessed in poloxamer-407 induced hyperlipidemic mice model. The butanol fraction and its isolated compound, quercetin-3-O-rhamnoside, significantly reduced the blood triglyceride and total-cholesterol level and increased the blood HDL-cholesterol level. They also showed the significant reductive effect on the blood AST and ALT level, rising in proportion to the liver damage, in hyperlipidemic mice.

In order to investigate the preventive and therapeutic effects of Herba Houttuyniae, experimental studies on the immune response and histological findings were undertaken. The results of these studies were summarized as follows; Delayed type hypersensitivity and rosette formation rate were significantly increased compared with control group. Hemagglutination, hemolysin titer and NK cell activity were variable, not significantly against the control group. When observed on lung tissue recovery; experimental groups were shown to be significantly recovered as compared with the control group. From these results, it is suggested that Houttuyniae Herba promotes immune response and reduces the recovery time of pneumonitis and lung abscess from the histological viewpoint.

Houttuynia cordata Thunb. grown in wet earth in China, Japan and Korea, has often been cited in medical literature for its medicinal effects. In this paper, the pharmaceutical effects of Houttuynia cordata Thunb., featured in the East Asian literature were studied. It was revealed that it has a wide variety of uses, including remedial treat-ments for pneumonia, antidote, inflammation, syphilis, abscess, paralysis and gynecological diseases. Its application methods also are numerous: drinking as tea or squeezed juice, application to wounds, wet dressing, chewing raw roots and mixing with other plants, liquor and food materials. The major pharmaceutical effects are as follows: antibiosis, immunity enhancement, urination, pain relieving, vasodilator and cough lozenge.

This study was performed to evaluate the effect of HCB on the bone mass and its related factors in estrogen-deficient animal model. The model rats of osteoporosis showed a significant decrease in bone density, bone ash density, calcium content of femur bone. At the 14th day after ovariectomy-surgery, rats were administered with HCB, extract of Houyttnia cordata, per orally, and continued for 10 weeks. And osteoporosis related parameters were determined to investigate the effect of HCB. Osteoporotic rats showed lower serum estrogen level, higher body weight than normal rats, and showed atrophy of uterine horns.
