Summary
Bee pollen is a natural mixture of floral pollen, nectar, and honeybee secretions used as a functional food and medicinal agent [PMID:35889814, PMID:34072636]. It is recognized for its diverse biological activities, including antioxidant, anti-inflammatory, and antimicrobial properties [PMID:38067498, PMID:34974697].
Background
Bee pollen is collected by honeybees (Apis mellifera) from flower stamens and consists of a cocktail of floral nectar, flower pollen, enzymes, and salivary secretions [PMID:35889814, PMID:40153343]. When stored in hives and fermented by microbes, it is transformed into bee bread [PMID:33670262, PMID:38002206].
Traditional uses
Bee pollen has been used since ancient times in medicine [PMID:32012913]. Documented uses include public health applications in the Bible and ancient Egyptian texts [PMID:34072636], skin whitening and beauty in ancient China [PMID:30111679], and the treatment of colds, flu, ulcers, premature aging, anemia, and colitis [PMID:28732430].
Active compounds
Bee pollen is rich in proteins, amino acids, polysaccharides, lipids, minerals, vitamins, and polyphenols [PMID:35889814, PMID:34072636]. Specific bioactive compounds include flavonoids (such as chrysin, apigenin, kaempferol, quercetin, galangin, pinocembrin, and naringenin), phenolic acids, hydroxycinnamoyl acid amides (HCAAs), carotenoids, and phytosterols [PMID:32012913, PMID:40153343, PMID:36670977, PMID:27013064].
Mechanism of action
Bee pollen exerts effects through its polyphenols (anti-inflammatory), phytosterols and fatty acids (anticancerogenic), and polysaccharides (immunological stimulation) [PMID:31756937]. HCAAs specifically inhibit hyaluronidase activity and leukotriene B4 (LTB4) release [PMID:40153343]. Wall-disruption of the pollen grains is noted to enhance the release and digestion of nutrients and bioactivities [PMID:38309905].
Clinical evidence
Evidence DChronic non-bacterial prostatitis (CNP)
Rapeseed bee pollen, particularly in high doses and wall-disrupted form, effectively alleviated CNP by regulating gut microbiota and reducing proinflammatory cytokines (IL-6, IL-8, IL-1β, and TNF-α) [PMID:37486857]
Evidence DAllergic rhinitis
Australian bee pollen extracts inhibited nasal secretion in a guinea pig rhinitis model [PMID:40153343]
Evidence CSkin care/Wound healing
Bee pollen is used to heal burn wounds and possesses antibacterial, anti-inflammatory, and antioxidant properties for skin treatment [PMID:32012913]
Safety & adverse effects
Bee products are generally well tolerated with no evidence of causing liver injury [PMID:35593876]. However, there are reports of immediate hypersensitivity to bee pollen granules [PMID:29788120]. Additionally, recent research indicates the occurrence of mycotoxins in bee pollen, sometimes exceeding safe intake levels [PMID:42188609].
Evidence summary
The evidence consists primarily of review articles (Level C) and in vitro or animal studies (Level D). While there is strong theoretical support for its nutritional and bioactive properties, large-cohort clinical studies are required to validate therapeutic claims [PMID:27013064].
