Is Taking Chicken Essence Effective?

I still remember when I was in secondary school, whenever I’m near to exam my mom will buy Brand’s Essence of Chicken for me.. So how effective exactly it is?

I Googled and found a few scientific research papers.. Believe it or not? Up to u 🙂

Stress is a common phenomenon. Every individual  experiences it. There are many ways of combating stress. Stress is necessary for preparation against challenging situations and danger. It is necessary to have stress before a test so that we are prepared. For instance, stress actually motivates students to prepare for examination but excessive stress can lead to poor performance. This study evaluates the effect of a commercial essence of chicken (CEC) on the various parameters related to stress and cognition of human volunteers. CEC is produced by a hot-water extraction process from chicken meat under high  pressure condition. It contains concentrated amounts of proteins, amino acids and peptides such as carnosine compared to homemade traditional chicken soup. Due to the unique extraction process, it has been postulated that readily absorbed amino acids and bioactive peptides are present in CEC. In this experiment, we evaluated the effect of CEC in comparison with a placebo and carageenan on a group of stressed medical students before their examinations. Students were divided into three groups at random and given either CEC, placebo or a carageenan drink daily for two weeks. Before and after the two weeks, the students were given a series of tests to assess their mental and physical wellbeing as well as attention and memory. The tests were the general health questionnaire (GHQ), SF36, digit span, construction of figures, 3-min memory test, comprehension and mental arithmetic. The students who ingested essence of chicken fared significantly better than the other two groups of students. The ability of essence of chicken to control anxiety by distraction and promoting attention and memory is discussed.

Folk wisdom suggests that chicken extract is useful for recovery from physical and mental fatigue. To explore this question, the physiological effect of Brand’s Essence of Chicken (BEC), a popular chicken extract used as a traditional remedy, was assessed during recovering from mental stress. We quantitated the blood levels of stress-related substances, and examined the task performance and subjects’ mood states during mental workloads. Subjects were 20, healthy male students who have never tasted BEC. They took two bottles of BEC or a placebo (70 ml/bottle) daily in the morning for 7 days. On the final experimental day, two mental workload tests were performed: (A) a mental arithmetic test (MAT; 1600 trials of two or three figure-addition or subtraction for 40 min). (B) a short-term memory test (SMT; 20 trials of memorizing 9 digit numbers). Blood was collected before and after each workload task. After the mental workload, the recovery of mean cortisol level of subjects who consumed BEC was significantly faster than that for those consuming the placebo. The task performance of subjects performing the MAT and SMT was also improved with BEC consumption compared with placebo. According to the profile of mood state questionnaire, subjects felt more active and less fatigued during the workload when they took BEC regularly. We conclude that the extract of chicken has the potential to metabolize stress-related substance in blood and to promote recovery from mental fatigue.

Aims This study investigated the effects of essence of chicken (EOC) on immunological responses, free radicals and blood glucose concentrations in normal and burn wound rat models. Methods This thesis reports an experimental study on Sprague-Dawley rats with a 3-group time-series design: a sham operated group (UNBURN) (n=72), a bum inflicted group (BURN) (n=72) and a no treatment group (CONTROL) (n=24). Rats in the UNBURN and BURN groups were further subdivided by intake of normal saline (NS), gelatin (GEL) and essence of chicken (EOC) (n=24 each group). Blood samples were taken on days 1, 8, 15 and 22 postbum to measure concentrations of serum immunoglobulin G (IgG), immunoglobulin A (IgA), immunoglobulin M (IgM), plasma nitric oxide (NO), lipid peroxidation (LPO) and blood glucose. ANOVA was used for statistical analysis and the level of significance was set at p<0.05. Results Results demonstrate significant increases in serum IgG, IgA and 1gM concentrations in both the GEL and EOC subgroups of the BURN and UNBURN groups in comparison to the placebo (NS) group on different postbum days. A significant elevation of IgG was found in the GEL and EOC subgroups of the UNBURN group on days 1 (p=0.026) and 8 (p=0.0l3) respectively. Similar results were observed in the GEL (p=0.001) and EOC (p=0.0l7) subgroups of the BURN group on day 8. There was a significant increase in IgA in the GEL and EOC subgroups for both the BURN and UNBURN groups. In the EOC subgroups, IgA increased significantly on day 15 for the UNBURN group and day 22 for the BURN group (p<0.050 and p=0.029 respectively), whereas in the GEL subgroups, it was found to be higher on day 15 for the UNBURN group and day 22 for the BURN group (p<0.050 and p=0.034 respectively). Conversely, IgA dropped significantly in the GEL subgroup of the BURN group on days 1 and 15 (p=0.038 and p=0.035 respectively). A significant increase in IgM was observed in the EOC subgroups of both the BURN and UNBURN groups and that of the GEL subgroup in the UNBURN group. IgM increased significantly in the EOC subgroup of both the BURN and UNBURN groups, on day 15 (p=0.040) for the BURN group and days 1 and 22 (p=0.010 and p<0.050 respectively) for the UNBURN group, whereas in the GEL subgroup of the UNBURN group it was noted on day 22 only (p=0.025). Blood glucose elevation was only observed in the EOC and GEL subgroups of the BURN group. Significant increases were noted in the EOC on days 1 and 22 (p=0.045 and p=0.0l9 respectively), whereas in the GEL subgroup, the increase was found on day 22 only (p=0.019). Similarly, significant changes in nitric oxide (NO) concentrations were also observed in the EOC and GEL subgroups of the BURN group only. However, there was a significant drop on day 15 for the EOC (p=0.002) and GEL subgroups (p=0.024). Concomitantly, a significant decrease in lipid peroxidation (LPO) was noted in the EOC subgroup of the BURN and UNBURN groups (p=0.006 and p=0.018 respectively), whereas a similar result was only observed in the GEL subgroup of the BURN group (p=0.023) on day 8. Conclusion Results support the contention that EOC enhances serum immunoglobulin concentrations in both normal and bum-inflicted rats. The findings demonstrate that EOC suppressed NO and LPO concentrations in burned rats and that of LPO in normal rats. Therefore, EOC consumption may increase immunological response and prevent free radical-mediated diseases. Further, EOC has shown potential to regulate blood glucose after burn injury by maintaining a stable glucose supply for metabolic needs, which may facilitate wound healing.

The nutritional essence of chicken (EOC) sold in domestic currently is rich in active ingredients such as proteins, peptides, a variety of minerals and trace elements. It is mainly used to supplement nutrition and improve health. Recent studies showed that EOC can reduce the levels of cortisol and some other tension materials in blood during fatigue, thus, improve mental fatigue, raise short-term memory capacity and enhance concentration. In addition, EOC can also significantly improve resting energy consumption, promoting metabolism and ameliorating physical and mental fatigue. As a post-natal nutrition, it can nourish the body, restore strength of parturition, promote early lactation and increase the volume of breast milk. The carnosine and anserine which are the nutritional contents in EOC are antioxidants that have many physiological activities. Moreover, as the precursor of transmitter of histaminergic neuron system, carnosine can effectively regulate the level of histamine controlled by centric self-consciousness through histidine metabolic pathway. As EOC can enhance the activity of 5-HT and activate 5-HT-dependent physiological activities, it is good at improving the quality of sleep, elevating mood and regulating circadian rhythm. In an effort to provide useful information for consumers and further researches on EOC, this paper summarizes the recent studies on possible mechanisms underlying the anti-stress and anti-fatigue activities of EOC.
