Propolis and Curcumin Outperform Steroid in Repairing Nerve Damage

A new study finds that using Propolis or Curcumin outperforms steroid use in boosting the return of functional nerve usage after a crush injury of the Sciatic nerve. A postive advance in using traditional solutions as an alternative to steroids...

An Experimental Comparison of the Effects of Propolis, Curcumin, and Methylprednisolone on Crush Injuries of the Sciatic Nerve

Propolis and curcumin have antioxidant, anti-inflammatory, immunomodulatory, and neuroprotective features. The goal of this study was to determine the effects of propolis and curcumin on nerve healing in rat sciatic nerve crush injuries and to compare these effects with results obtained using steroid treatment.

In the sham group, the right sciatic nerves of rats were dissected and exposed, and the skin was closed without any additional manipulation. In the control group (group C), after the right sciatic nerves of rats were exposed, crush damage was inflicted using a surgical clamp. In the control-methylprednisolone group, crush injuries were inflicted on sciatic nerves as in group C. After injury, 1-mg/kg methylprednisolone was administered daily for 6 days and was then tapered for 4 days. In the curcumin group, crush injuries were inflicted on sciatic nerves as in group C. Then, 100-mg/kg curcumin was given every day. In the propolis group, crush injuries were inflicted on sciatic nerves as in group C. Then, 200-mg/kg propolis was given every day. Rats were evaluated after 28 days using functional (walking track analysis and electrophysiological measurements), histomorphometric, electron microscopic, and muscle weight measurements.

Compared to the control groups, the curcumin and propolis groups had better functional (walking track analysis and electrophysiological) results after experimental peripheral nerve crush injury.


Curcumin and propolis, 2 traditional drugs, had a positive effect on nerve crush injuries. We are convinced that they can be used to support routine treatment in such nerve injuries.

Bee Venom Restores Hormonal Imbalance

Interestingly enough, this effect was observed with women undergoing bee venom therapy (BVT) for other maladies, such as Multiple Sclerosis. While receiving BVT, they became pregnant, which they had found to be impossible prior to BVT sessions. It's good to see that even side effects of honey bees have a positive touch ...

Effect of bee venom on IL-6, COX-2 and VEGF levels in polycystic ovarian syndrome induced in Wistar rats by estradiol valerate

Polycystic ovarian syndrome (PCOS) is a low-grade inflammatory disease characterized by hyperandrogenemia, hirsutism, chronic anovulation and vascular disorder. Interleukin-6 (IL-6), cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) are triggered by inflammatory stimuli and lead to angiogenesis and pathogenesis of the ovary. Honeybee venom (HBV) contains an array of biologically active components possessing various pharmaceutical properties. This study was designed to assess the possibility of HBV application as an anti-inflammatory therapeutic agent to suppress levels of the main inflammatory mediators IL-6, COX-2 and VEGF.
To induce PCOS, 1 mg of estradiol valerate (EV) per 100 g of body weight was subcutaneously (SC) injected into eight-week-old rats. After 60 days, 0.5 mg/kg of HBV was administered Intraperitoneal (IP) for 14 consecutive days, and the results of PCOS treatment were investigated. Rats were then anesthetized with CO2, and the ovaries were surgically removed. Serum IL-6 was detected by the ELISA kit. Immunoexpression of COX-2 and VEGF were examined in three groups: EV-induced PCOS, HBV-treated PCOS and control animals.

Thickness of theca layer, number and diameter of cysts and levels of IL-6 significantly decreased in HBV group relative to PCOS group. The immunohistochemical analysis showed an increase in COX-2 and VEGF expression in PCOS group whereas HBV-treated rats presented weak and irregular immunostaining.

Based on the results presented in this study, we can conclude that anti-inflammatory effects of HBV can restore metabolic and reproductive features of PCOS. Decreased levels of IL-6, COX-2, VEGF and serum androgens, and increased number of corpora lutea are suggestive of therapeutic effects of HBV on PCOS. We have established that this effect of HBV is mediated by suppression of inflammatory and angiogenic factors.

Higher Levels of Royal Jelly Component found in Western China

Since 98% of the world's supply of Royal Jelly comes from China, this study is significant on two aspects. Royal Jelly, made by worker bees for the queen, rely on pollen to produce this special gelatin. Geographic location is very important. But the other significant development is the type of honey bee used. This study reviewed three varieties of Apis mellifera, including a hybrid. Using 10-HDA is an important measure of quality, due to its ability to aid neurogenesis... 

Geographical Influences on Content of 10-Hydroxy-trans-2-Decenoic Acid in Royal Jelly in China

The content of 10-hydroxy-trans-2-decenoic acid (10-HDA), a marker compound in royal jelly (RJ), is the most important criterion in grading RJ for commercial trade and varies with its origin. To identify the effect of geographical origin on 10-HDA content in RJ, 138 samples were collected from 19 provinces of China (divided into three groups) produced by either Apis mellifera ligustica Spinola, 1806 or a hybrid of A. m. ligustica and Apis mellifera carnica Pollman, 1879 and analyzed for moisture, sugar, crude protein, ash, acid, and 10-HDA concentration.

The results show that RJ from western China has a significantly higher 10-HDA level (2.01 ± 0.05%) than those from northeastern (1.87 ± 0.05%) and eastern (1.75 ± 0.03%) China. RJ secreted by hybrid bees contained more 10-HDA (1.89 ± 0.03%) than that secreted by A. m. ligustica (1.78 ± 0.03%). The 10-HDA content of RJ produced during flowering of rape (Brassica campestris L.), lime (Tilia amurensis Ruprecht), and vitex (Vitex negundo L. variety heterophylla (Franch.) Rehder) was 1.92,1.80, and 1.68%, respectively.
The results would be helpful during the process of price determination of RJ by providing some basis of geographical, bee strain, and botanical information for commercial trade.

Bee Products Reduce Toxic Damage from Agrichemicals

A common thread found in all bee products is antioxidant potency. This study found their effects reversed oxidatitve damage caused by agrichemical contamination in an aquacultural setting. The results are evident, not only with aquatic life but in this study they also included a common ground water contaminant, which is known for causing infant birth defects. Bee products are a natural protective addition for creatures with or without legs...

Bee Products Prevent Agrichemical-Induced Oxidative Damage in Fish

In southern South America and other parts of the world, aquaculture is an activity that complements agriculture. Small amounts of agrichemicals can reach aquaculture ponds, which results in numerous problems caused by oxidative stress in non-target organisms. Substances that can prevent or reverse agrichemical-induced oxidative damage may be used to combat these effects. This study includes four experiments.

In each experiment, 96 mixed-sex, 6-month-old Rhamdia quelen (118±15 g) were distributed into eight experimental groups: a control group that was not exposed to contaminated water, three groups that were exposed to various concentrations of bee products, three groups that were exposed to various concentrations of bee products plus tebuconazole (TEB; Folicur 200 CE™) and a group that was exposed to 0.88 mg L-1 of TEB alone (corresponding to 16.6% of the 96-h LC50).

We show that waterborne bee products, including royal jelly (RJ), honey (H), bee pollen (BP) and propolis (P), reversed the oxidative damage caused by exposure to TEB. These effects were likely caused by the high polyphenol contents of these bee-derived compounds. The most likely mechanism of action for the protective effects of bee products against tissue oxidation and the resultant damage is that the enzymatic activities of superoxide dismutase (SOD), catalase (CAT) and glutathione-S-transferase (GST) are increased.

Thyme Honey Validated to Possess Wound Healing Capacities

Ironically, this has been proven and practiced in France at the Central Hospital Unit in Limoges. Prof. Descottes conducted numerous double-blind studies that confirmed Thyme Honey's ability to heal wounds better and faster than pharmaceutically prescribed treatments as well as other monofloral honeys. He also proved that other honeys can heal wounds too, but that Thyme honey was the best...

Honey-induced macrophage stimulation: AP-1 and NF-κB activation and cytokine production are unrelated to LPS content of honey
Int Immunopharmacol, 2013 Oct 11

Honey is well known for its wound healing properties although the cellular and molecular mechanisms underlying honey-stimulated healing process are still poorly understood. The present study was intended to characterize the stimulation of Raw 264.7 murine macrophages in response to thyme honey.
Honey induces significant increase in PGE2 production, and overexpression of both COX-2 and TNF-α (p < 0.001). This increase was concomitant with overexpression and activation of the AP-1 and NF-κB transcription factor subunits. The small LPS content of honey could not, by itself, account for the reported observations.

These results suggest that other thyme honey components participate in the stimulation of cytokine production required for effective wound healing process.
