Royal Jelly Boosts Red Blood Cells, Mental Health & Glucose Tolerance

Contrary to popular belief, consuming Royal Jelly even at elevated levels up to 10g per day is possible, in fact, even beneficial, on a case-dependent basis. Imagine what results that could produce in light of the small quantity they used in this study?

Effect of Royal Jelly Ingestion for Six Months on Healthy Volunteers
Nutrition Journal, 2012 Sep 21

BACKGROUND:
Royal jelly is a widely ingested supplement for health, but its effects on humans are not well known. The objective was to evaluate the effects of long-term royal jelly ingestion on humans.

METHODS:
We conducted a randomized placebo-controlled, double-blind trial. A total of 61 healthy volunteers aged 42-83 years were enrolled and were randomly divided into a royal jelly group (n = 31) and a control group (n = 30). Three hundred mg of royal jelly (RJ) or a placebo in 100 ml liquid/day were ingested for 6 months. The primary outcomes were changes in anthropometric measurements and biochemical indexes from baseline to 6 months after intervention.

RESULTS:
Thirty subjects in the RJ group and 26 in the control group were included in the analysis of endpoints. In an adjusted mean change of the variables from the baseline, significant differences between the two groups could be found in red blood cell counts (+0.16x106 /muL for the RJ group vs. -0.01x106 /muL for the control group, P = 0.0134), hematocrit (+0.9% vs. -0.8%, P = 0.0251), log (fasting plasma glucose) (+0.01 +/- 0.01 log mg/dL vs. +0.05 +/- 0.01 log mg/dL, P = 0.0297), log (insulinogenic index) (+0.25 vs. -0.13, P = 0.0319), log dehydroepiandrosterone sulfate (DHEA-S) (+0.08 log mug/dL vs. +0.20 log mug/dL, P = 0.0483), log testosterone (T) (+0.12 +/- 0.04 log ng/mL vs. -0.02 +/- 0.05 log ng/mL, P = 0.0416), log T/DHEA-S ratio (+0.05 +/- 0.05 vs. -0.23 +/- 0.59, P = 0.0015), and in one of the SF-36 subscale scores, mental health (MH) (+4 vs. -7, P = 0.0276).

CONCLUSIONS:
Six-month ingestion of RJ in humans improved erythropoiesis, glucose tolerance and mental health. Acceleration of conversion from DHEA-S to T by RJ may have been observed among these favorable effects.

Propolis Flavonoid Has Chemotherapeutic Effect

Propolis has numerous flavonoids, each with certain properties, frequently overlapping with other bioflavonoids. Such is the case with Galangin, a flavonoid commonly identified in areas where Poplar trees are present. It also possesses antimicrobial, antimycotic (anti-fungal), bacteriostatic and wound healing properties... 

Galangin Induces B16F10 Melanoma Cell Apoptosis Via Mitochondrial Pathway and Sustained Activation of p38 MAPK
Cytotechnology, 2012 Sep 22

Galangin, an active flavonoid present at high concentration in Alpinia officinarum Hance and propolis, shows cytotoxicity towards several cancer cell lines, including melanoma. However, the specific cellular targets of galangin-induced cytotoxicity in melanoma are still unknown.

Here, we investigated the effects of galangin in B16F10 melanoma cells and explored the possible molecular mechanisms. Galangin significantly decreased cell viability of B16F10 cells, and also induced cell apoptosis shown by Hoechst 33342 staining and Annexin V-PI double staining flow cytometric assay.

Furthermore, upon galangin treatment, disruption of mitochondrial membrane potential was observed by JC-1 staining. Western blotting analysis indicated that galangin activated apoptosis signaling cascades by cleavage of procaspase-9, procaspase-3 and PARP in B16F10 cells. Moreover, galangin significantly induced activation of phosphor-p38 MAPK in a time and dose dependent manner. SB203580, an inhibitor of p38, partially attenuated galangin-induced apoptosis in B16F10 cells.

Taken together, this work suggests that galangin has the potential to be a promising agent for melanoma treatment and may be further evaluated as a chemotherapeutic agent.

Honey Protects Humans From Chronic Diseases

This is a gem of a study! It identifies several important elements 1) role of phenolic compounds, i.e., nectar sources 2) flavonoids aid human health 3) positive glycemic effect. Now, beekeepers need to improve processing practices that preserve these elements and educate consumers honey is also medicine and should not be clear as water and remain liquid for life (except for a few rare sources, such as Acacia Honey)...


Honey as a Source of Dietary Antioxidants: Structures, Bioavailability and Evidence of Protective Effects Against Human Chronic Diseases
Curr MedChem, 2012 Dec 28

In the long human tradition honey has been used not only as a nutrient but also as a medicine. Its composition is rather variable and depends on the floral source and on external factors, such as seasonal, environmental conditions and processing.

In this review, specific attention is focused on absorption, metabolism, and beneficial biological activities on human health of honey compounds.
Honey is a supersaturated solution of sugars, mainly composed of fructose (38%) and glucose (31%), containing also minerals, proteins, free amino acids, enzymes, vitamins and polyphenols. Among polyphenols, flavonoids are the most abundant and are closely related to its biological functions.

Honey positively affects risk factors for cardiovascular diseases by inhibiting inflammation, improving endothelial function, as well as the plasma lipid profile, and increasing low-density lipoprotein resistance to oxidation. Honey also displays an important antitumoral capacity, where polyphenols again are considered responsible for its complementary and overlapping mechanisms of chemopreventive activity in multistage carcinogenesis, by inhibiting mutagenesis or inducing apoptosis.

Moreover, honey positively modulates the glycemic response by reducing blood glucose, serum fructosamine or glycosylated hemoglobin concentrations and exerts antibacterial properties caused by its consistent amount of hydrogen peroxide and non-peroxide factors as flavonoids, methylglyoxal and defensin-1 peptide.

In conclusion, the evidence of the biological actions of honey can be ascribed to its polyphenolic contents which, in turn, are usually associated to its antioxidant and anti-inflammatory actions, as well as to its cardiovascular, antiproliferative and antimicrobial benefits.

Propolis Protects Kidneys from Aluminum Toxicity

Propolis is the natural protector for humans and animals. It's been proven in numerous studies to protect the body from commonly occuring illnesses, as well as more toxic situations, such as this example. You'll find even more references to its protective nature with other internal organs such as the liver and the intestines in this blog...


Role of Propolis (Bee Glue) in Improving Histopathological Changes of the Kidney of Rat Treated with Aluminum Chloride
EnvironToxicol, 2012 Nov 22

Humans are frequently exposed to aluminum from various food additives, therapeutic treatments and the environment, and it can be potentially toxicThis study is aimed to elucidate the protective effects of propolis against aluminum chloride (AlCl(3) )-induced histopathological and immunohistochemical changes in kidney tissues of rats. 

Sixty Wistar Albino male rats (average weight 250-300 g) were divided into three equal groups. The first served as a negative control. The second received AlCl(3) (34 mg/kg bw, 1/ 25 LD 50). The third were administered AlCl(3) (34 mg/kg bw, 1/ 25 LD 50) plus propolis (50 mg/kg bw). Doses were given once daily via a gavage for 8 weeks every day.

The results showed that shrunken glomeruli, intraglomerular congestion, loss of apical microvilli, degeneration of mitochondria and widened rough endoplasmic reticulum were also observed in the Proximal Convoluted Tubules of these animals. Treatment with propolis ameliorated the harmful effects of AlCl(3) ; this was also proved histopathologically by the noticeable improvement in the renal tissues. There were also significant variations in the expressed of ki-67 and p53 proteins.

It can be concluded that propolis may be promising as a natural therapeutic agent in AlCl(3) -induced renal toxicity and oxidative stress in rat kidneys.

Royal Jelly Improves Memory, Hope for Alzheimer Victims

Royal Jelly is frequently referred to as a "Brain Booster" and this study takes it another step further by demonstrating improved memory and spatial learning, significant relevance for Alzheimer sufferers. Another important finding is the use of freeze-dried Royal Jelly, which eliminates obstacles such as the bitter taste and inconvenience of consuming fresh Royal Jelly... 

Effect of Royal Jelly on Spatial Learning and Memory in Rat Model of Streptozotocin-Induced Sporadic Alzheimer's Disease
Adv BiomedRes, 2012;1:26

BACKGROUND:
It has been recently demonstrated that Royal jelly (RJ) has a beneficial role on neural functions. Alzheimer's disease (AD) is associated with impairments of learning and memory. Therefore, the present study was designed to examine the effect of RJ on spatial learning and memory in rats after intracerebroventricular injection of streptozotocin (icv-STZ).

MATERIALS AND METHODS:
Rats were infused bilaterally with an icv injection of STZ, while sham rats received vehicle only. The rats were feed with RJ-contained food (3% w/w) (lyophilized RJ mixed with powdered regular food) or regular food for 10 days. Then spatial learning and memory was tested in the rats by Morris water maze test.

RESULTS:
Results showed that in icv-STZ group latency and path length were increased as compared to sham group, also icv-STZ rats less remembered the target quadrant that previously the platform was located; however, these were protected significantly in STZ group that received RJ-containing food.

Synergistic Effects of Honey and Propolis Against Drug Resistant Strains

In documentation worldwide, you find this is consistently true - products of the hive have greater effects when consumed together. It makes sense, especially when you understand that they also work well with herbal remedies...


Synergistic Effects of Honey and Propolis Toward Drug Multi-Resistant Staphylococcus Aureus, Escherichia Coli and Candida Albicans Isolates in Single and Polymicrobial Cultures
Int J Med Sci, 2012;9

Background
Propolis and honey are natural bee products with wide range of biological and medicinal properties. The study investigated antimicrobial activity of ethyl alcohol extraction of propolis collected from Saudi Arabia (EEPS) and from Egypt (EEPE), and their synergistic effect when used with honey. Single and polymicrobial cultures of antibiotic resistant human pathogens were tested.
Material and methods
Staphylococcus aureus (S. aureus),), Escherichia coli (E. coli) and Candida albicans (C.albicans) were cultured in 10-100% (v/v) honey diluted in broth, or 0.08-1.0% (weight/volume) EEPS and EEPE diluted in broth. Four types of polymicrobial cultures were prepared by culturing the isolates with each other in broth (control) and broth containing various concentrations of honey or propolis. Microbial growth was assessed on solid plate media after 24 h incubation.
Results
EEPS and EEPE inhibited antibiotic resistant E.coli, and S.aureus, and C.albicans in single and polymicrobial cultures. S.aureus became more susceptible when it was cultured with E.coli or C.albicans or when all cultured together. C.albicans became more susceptible when it was cultured with S.aureus or with E.coli and S. aureus together. The presence of ethyl alcohol or honey potentiated antimicrobial effect of propolis toward entire microbes tested in single or polymicrobial cultures. EEPS had lower MIC toward E.coli and C.albicans than EEPE. When propolis was mixed with honey, EEPS showed lower MIC than EEPE. In addition, honey showed lower MIC toward entire microbes when mixed with EEPS than when it was mixed with EEPE.
Conclusion
1) propolis prevents the growth of the microorganisms in single and mixed microbial cultures, and has synergistic effect when used with honey or ethyl alcohol, 2) the antimicrobial property of propolis varies with geographical origin, and 3) this study will pave the way to isolate active ingredients from honey and propolis to be further tested individually or in combination against human resistant infections.
