of Bee Propolis, Honey and Royal Jelly

When it comes to bee pollen, propolis, and royal jelly, people either seem to
swear by them or swear at them.
Bee products epitomize everything that's right and wrong about natural foods and
dietary supplements. For a lot of people, the concept of eating "beestuff" -
other than honey - seems awfully strange. And while bee products have a faithful
following, few people really understand why they work. Scientifically, that is.
Propolis
Bees create propolis by collecting a resinous sap from trees and then mixing
it with wax back at the hive. They use this material much the way people use
caulk: to seal their homes. Chemically, propolis is exceedingly complex and
contains a rich variety of potent terpenes and benzoic, caffeic, cinnamic, and
phenolic acids. It's also high in flavonoids, which by themselves may account
for many of the benefits attributed to propolis and some researchers refer to
propolis as a type of flavonoid.
One of the most significant medical journal articles described how the caffeic
acids in propolis and honey might prevent colon cancer, which kills some 60,000
Americans each year. Chinthalapally V. Rao, Ph.D., of the American health
Foundation, Valhalla, N.Y., reported in Cancer Research (Sept.15,1993;
53:1482-88) that these caffeic acids prevented the formation of precancerous
tissue in rats after they were exposed to cancer-causing chemicals.
Most medical articles, however, still point to the value of propolis as a
powerful, natural antibiotic. That doesn't mean eating propolis will let you
throw away your antibiotics - only that you may not need them quite as often.
Why would bees need substances with broad antibacterial and antiviral
properties? Any beekeeper will tell you the answer. Bees are very susceptible to
bacterial and viral infections, which can destroy hives the way the bubonic
plague ravaged Europe in the 17th century.
Two medical journal articles document the activity of propolis specifically
against Staphylococcus aureus, the bacterium that causes dangerous and often
deadly surgical infections, blood poisoning, and a type of pneumonia. Five to 10
percent of all patients hospitalized in the United States develop such
infections, and S. aureus has become resistant to all but one pharmaceutical
antibiotic.
In a Chinese study, researchers found that extracts of propolis - specifically,
sinapic, isoferulic, and caffeic acids - inhibited the growth of S. aureus (Qiao
Z, China Journal of Chinese Materi Medica, Aug. 1991;16:481-2). A European study
reported that ethanol extracts from propolis had a "marked synergistic effect"
on the anti-staph activity of two antibiotics, streptomycin and cloxacillin, and
a moderate effect on several others (Krol W, Arzneimittel-Forschung, May
1993;43:607-9).
Another scientific investigation discovered that propolis inhibited the activity
of several streptococcal bacteria species that cause dental cavities. Japanese
researchers reported that propolis fed laboratory fats had far fewer cavities than
those given a regular diet. Propolis protected specifically against
Streptococcus mutans and several other strep species (Ikeno K, Caries research,
1991;25:347-51). These strep species are closely related to the germ that causes
strep throat.
Propolis works against bacteria in several ways. One study reported that it
prevented bacterial cell division and also broke down bacterial walls and
cytoplasm, which is how some prescription antibiotics work (Takaisi-KikuniNB,
Planta Medica, June 1994;60:222-7).
Perhaps more remarkable is that propolis acts against viruses, which antibiotics
do not. A number of medical journal reports have discussed the role of
propolisin fighting upper respiratory infections, such as those caused by the
common cold and influenza viruses (Focht J, Arzneimittel-Forschung, Aug.
1993;43:921-3). Other investigators have reported that the cinnamic acid
extracts of propolis prevent viruses from reproducing, but they worked best when
used during the entire infection (Serkedjieva J, Journal of Natural Products,
March 1992;55:294-302).
Underpinning many of the benefits of propolis is that some of its
components, like the flavonoids and ethanols, function as antioxidant
free-radical scavengers. A study published in the Journal of Ethnopharmacology
(Jan. 1994;21:9-13)noted that some of the antioxidant phenols in propolis
functioned similarly to vitamin E. In another article, researchers described
that propolis had anti-inflammatory properties and that it could also prevent
blood clots (Drugs Under Experimental & Clinical Research, 1993; 19:197-203).
Honey
Six medical journal articles over the past three years have also described the
antibiotic properties of honey. A physician at the medical college in
Maharashtra, India, recently explored the use of honey-soaked gauze to treat
burn patients. The 40 patients treated with honey healed in about half the time
- and with half the scar tissue - compared with patients treated by other means.
(Subrahmanyam M, Burns, Aug. 1994;20:331-3).
A team of researchers from the department of surgery, University Teaching
Hospital, Nigeria, reported that unprocessed honey "inhibited most of the fungi
and bacteria" causing surgical and wound infections. In a remarkable conclusion
in the journal Infection (Jul.- Aug. 1992;20:227-9), Dr. S. E. Efem and his
colleagues wrote, "Honey is thus an ideal topical wound dressing agent in
surgical infections, burns and wound infections."
Perhaps most remarkable is the effect of honey on Helicobacter pylori, the
bacterium now known to cause gastric ulcers. Because honey has long been a folk
remedy for dyspepsia, or stomach upset, a team of researchers from the
University of Waikato, New Zealand, tested whether honey would have any benefit.
Within three days, honey stopped the growth of H. pylori colonies obtained from
patients.
