Background: Indiscriminate use of antibiotics in livestock and poultry farming has caused emergence of new pathogenic strains. The situation has warrented the development of safe and alternative growth promoters and immunity enhancers in livestock. Herbal additives in animal and bird feed is a centuries-old practice. Thus, the present study investigated the efficacy of a standardized formulation of lipophilic turmeric extract containing curcumin and turmerones, (TF-36), as a natural growth promoter poultry feed additive. Methods: The study was designed on 180 one-day old chicks, assigned into three groups. Control group (T<sub>0</sub>) kept on basal diet and supplemented groups T<sub>0.5</sub> and T<sub>1</sub> fed with 0.5% and 1% TF-36 fortified basal diet for 42 days. Each dietary group consisted of six replicates of ten birds. Body weight, food intake, food conversion ratio, skin colour, blood biochemical analysis and antioxidant status of serum were investigated. Results: Body weight improved significantly in T<sub>1</sub> with a 10% decrease in FCR as compared to the control. TF-36 supplementation in T<sub>1</sub> enhanced the antioxidant enzyme activity significantly (p < 0.05) with a decrease (p < 0.05) in lipid peroxidation. It also caused a slight yellow skin pigmentation without any change in meat color, indicating the bioavailability of curcumin from TF-36. However, no significant change in the concentration of serum creatinine, total protein and liver enzyme activities were observed, indicating the safety. Conclusion: In summary, we concluded that TF-36 can be a natural feed additive to improve growth performance in poultry, probably due to the better antioxidant activity and antimicrobial effects contributed by the better bioavailability of curcuminoids and turmerones. Besides, curcuminoids and turmerones were also known to be gastroprotective and anti-inflammatory agents.

Acetaldehyde, the major cytotoxin formed by the metabolism of alcohol, is responsible for liver injury, extracellular matrix alterations, inflammation, and hangover in heavy drinkers. This study aimed to demonstrate the efficacy of a standardized polyphenolic extract of clove buds (Clovinol) in ameliorating the oxidative stress and inflammation caused by the accumulation of acetaldehyde after binge drinking. We used a randomized, double-blinded crossover study with 16 male social drinkers. The subjects were randomized into two groups of eight subjects and received either placebo or Clovinol in a single hard shell gelatin capsule (250 mg × 1) per day. The dosage of alcohol was 1 g/kg body weight/day. After 2 weeks of washout period, the treatment regime was reversed. Blood samples were drawn at 0, 0.5, 2, 4, and 12 h after treatment with either placebo or Clovinol, and biochemical parameters were analyzed. Hangover severity score was determined by using a validated questionnaire as reported earlier. Results showed faster elimination of blood acetaldehyde with significant decreases in oxidative stress, lipid peroxidation, C-reactive protein, interleukin-6, and significant enhancement in glutathione and superoxide dismutase as compared with placebo along with an overall reduction of 55.34% in hangover severity in Clovinol-treated subjects. This study demonstrated the efficacy of clove bud polyphenols for alleviating alcohol-related side effects among social drinkers at the studied dose.
