Propolis is a sticky dark-colored material showing a very complex chemical composition that honeybees collect from plants. It has been used in folk medicine since ancient times, due to several biological properties, such as antimicrobial, anti-inflammatory, antioxidant and immunomodulatory activities, among others. Its antitumor action in vivo and in vitro has also been reported, using propolis...

Immunoglobulins are part of the humoral immunity response against foreign antigens. Their blood levels could be influenced by different agents, including food supplements as Aphanizomenon flos-aquae (AFA), Propolis, substances as Fucoidan and herbal extracts. Purpose. To evaluate whether Fucoidan, AFA, a total leaf extract of Haberlea rhodopensis and Propolis augment the IgG and IgM levels into...

BACKGROUND Propolis is a resin collected by bees from plant buds and exudates, which is further processed through the activity of bee enzymes. Propolis has been shown to possess many biological and pharmacological properties, such as antimicrobial, antioxidant, immunostimulant and antitumor activities. Due to this bioactivity profile, this resin can become an alternative, economic and safe sour...

Propolis is a resinous mixture collected from plant buds and exudates by honeybees; this substance is used as a building insulation material in beehives (Greenaway et al. 1990). Because of its wide use in folk medicine, propolis has been the subject of intense pharmacological and chemical study for almost 30 years (Bankova 2005). It has recently gained popularity as a food supplement and is use...

Because propolis contains many types of antioxidant compounds such as polyphenols and flavonoids, it can be useful in preventing oxidative damages. Ethyl acetate extracts of propolis from several Algerian regions show high activity by scavenging free radicals, preventing lipid peroxidation and inhibiting myeloperoxidase (MPO). By fractioning and assaying ethyl acetate extracts, it was observed ...

The bees of the Meliponini tribe, known as stingless (SB), elaborate a distinct type propolis, whose application potential is largely unexplored. Currently, there some knowledge pharmacological activities propolis from Apis mellifera, however, little about diversity and antimicrobial activity especially in relation to pathogens agricultural importance. This study aimed investigate alcoholic ext...

Propolis has shown activity against pathogenic microorganisms that cause diseases in humans and animals. The ethanol (Et-Blg) and acetone (Ket-Blg) extracts from a Bulgarian propolis, with known chemical compositions, presented similar activity against tissue culture-derived amastigotes. The treatment of Trypanosoma cruzi-infected skeletal muscle cells with Et-Blg led to a decrease of infection...

The effect of Persian bee propolis and pollen extracts on innate immune response of rainbow trout (Onchorhynchus mykiss) was investigated. Fish were fed diets containing 1% Pollen, 1% propolis and combination of the two immune-stimulants (0.5% Pollen and 0.5% propolis) as treatment groups and fed without the two immune-stimulants as positive and negative control groups for 4 weeks. The effects ...
