Nosema C

[Hivemaker.]

Nozevit.........Nosevit is a traditional bark extract from Central Europe. Dr. Joe Carmen uses it successfully to winter bees in Alaska! Joe says that it is the only product used in Croatia, Bosnia, Slovenia, Serbia and other close countries.

Our preparation Nozevit, is produced from all natural substances according to a decades old traditional European recipe. After many years of university studies and field testing to standardize Nozevit, it was introduced to European beekeepers in 2003. After 5 years of commercial success in Europe, Nozevit is now available in North America.
Healthy bee colonies build brood faster in the spring, and will winter extremely well when their intestinal integrity is intact. Exceptional colonies can be built using all natural Nozevit as a food supplement for intestinal cleansing, thereby reducing the need of chemical treatments for internal ailments.

Is that a posh way of saying its made from essential oils extracted from the tree bark?

Yep,it most likely is,i use emulsified thymol.

Thanks Hivemaker,thats what I was trying to work out,the fact that the 2 products are very simular to a Thymol preparation you can make yourself

Abstract - The aim of this study was to evaluate the effect of thymol and resveratrol administered in two different formulation modes (candy and syrup) on the development of Nosema ceranae and on the longevity of honey bees. Emerging bees from a nosema-free apiary were individually infected with 1 $\mu $L of sucrose syrup containing 18000 spores of N. ceranae, placed in cages, and kept in an incubator at 33 °C and 65% RH. The experimental groups were fed candy or syrup prepared with thymol (100 ppm) or resveratrol (10 ppm). Infection levels were monitored over a 25 day period by removal and dissection of two live bees per cage. On day 25, post-infection bees fed with thymol syrup had significantly lower levels of infection ($60 \pm 9$ million spores/bee) compared to control bees ($138\pm7$ million spores/bee). Bees fed with thymol or resveratrol syrup lived significantly longer (23 and 25 days, respectively) than bees fed with control syrup (20 days). Thymol treated syrup appears to be promising in the control of nosema infection.

Abstract - The potential of some natural compounds (thymol, vetiver essential oil, lysozyme, resveratrol) for the control of nosema infection in honeybees was evaluated. A first trial aimed at screening substances, in candy preparations, on the basis of their toxicity to honeybees and bees' dietary preferences. None of the tested substances showed an increased bee mortality or decreased bee preference, and were therefore considered suitable for further testing. In the second trial the effects of the natural compounds on nosema diseased honeybees were evaluated: bees were individually dosed with nosema spores and fed candies prepared with the screened substances. The results showed that bees fed with thymol and resveratrol candies had significantly lower infection rates, and bees supplied with resveratrol prepared candy also lived significantly longer. We suggest that thymol and resveratrol could be useful in alternative strategies for the control of nosema disease.
