Pharmacodynamics — Vaccinium oxycoccos

The pharmacodynamic properties of cranberry are determined by the high content of type A proanthocyanidins, anthocyanins, phenolic acids, flavonols, and organic acids. The complex of biologically active compounds exhibits a pronounced antioxidant effect due to the ability to neutralize reactive oxygen species, inhibit lipid peroxidation processes, and stabilize cell membranes. In relation to the urinary system, an anti-adhesive effect has been established, associated with the disruption of bacterial fimbriae attachment to epithelial cells, which reduces mucosal colonization. The anti-inflammatory effect is realized through the modulation of pro-inflammatory cytokine synthesis and a reduction in the activity of cyclooxygenase pathway enzymes, leading to a decrease in the production of inflammatory mediators. In the cardiovascular system, an endothelioprotective effect is noted, along with improved nitric oxide bioavailability and reduced platelet aggregation. The metabolic effect is associated with the modulation of lipid metabolism and a reduction in low-density lipoprotein oxidation. At the level of the immune system, a moderate immunomodulatory effect is noted with an enhancement of the barrier function of mucous membranes.

Reference: Howell A. et al., 2010, Bioactivity of cranberry proanthocyanidins, Phytochemistry, 71(7), 699–708 (https://pubmed.ncbi.nlm.nih.go...)

Pharmacokinetics — Vaccinium oxycoccos

Active phenolic compounds of cranberry, when administered orally, are absorbed primarily in the small intestine, and are partially metabolized by the colonic microflora to form low-molecular-weight phenolic metabolites. Distribution occurs with the participation of plasma proteins, with predominant accumulation in the tissues of the urinary system. Metabolism occurs in the liver by conjugation with glucuronic acid and sulfation. Excretion occurs primarily by the kidneys in urine, and partially through bile. With topical application, systemic absorption is minimal and is limited to the superficial layers of the skin or mucous membranes.

Mechanisms of Action and Scientific Rationale — Vaccinium oxycoccos

The mechanisms of action of cranberry are mainly associated with the presence of type A proanthocyanidins, anthocyanins, quercetin, myricetin, ursolic acid, and phenolic acids. Type A proanthocyanidins have the ability to alter the spatial configuration of bacterial adhesins, in particular fimbrial structures, which prevents their binding to receptor molecules of uroepithelial cells. This effect is realized without direct bactericidal action and is considered as a mechanism for blocking mucosal colonization. Reference: Howell A.B. et al., 1998, Inhibition of the adherence of P-fimbriated Escherichia coli to uroepithelial-cell surfaces by proanthocyanidin extracts from cranberries, New England Journal of Medicine, 339(15), 1085–1086 (https://pubmed.ncbi.nlm.nih.go...).

The antioxidant mechanism is realized through the direct neutralization of reactive oxygen species and the suppression of intracellular signaling cascades that regulate the expression of pro-inflammatory genes. Polyphenolic components reduce the activity of the nuclear factor involved in the transcription of inflammatory mediators, and also modulate the activity of cyclooxygenase and lipoxygenase enzymes, which leads to a decrease in the synthesis of prostaglandins and leukotrienes. This substantiates the anti-inflammatory potential of the taxon at the level of cellular and tissue structures. Reference: Neto C.C., 2007, Cranberry and its phytochemicals: A review of in vitro and in vivo studies, Journal of Nutrition, 137(1), 186S–193S (https://pubmed.ncbi.nlm.nih.go...).

In the cardiovascular system, cranberry polyphenols contribute to an increase in nitric oxide bioavailability by reducing endothelial oxidative stress and inhibiting low-density lipoprotein oxidation. A decrease in platelet aggregation activity has been observed, which is associated with an effect on the thromboxane pathway and modulation of calcium fluxes in platelets. Additionally, an effect on signaling pathways regulating the expression of endothelial cell adhesion molecules has been demonstrated. Reference: Ruel G. et al., 2006, Effects of cranberry juice consumption on endothelial function in men, British Journal of Nutrition, 96(2), 357–364 (https://pubmed.ncbi.nlm.nih.go...).

The metabolic effect is due to the ability of anthocyanins and flavonols to influence the expression of genes involved in the regulation of lipid metabolism, as well as the activity of enzymes associated with the synthesis and oxidation of fatty acids. Polyphenols interact with receptors that regulate energy homeostasis and modulate intracellular signaling cascades associated with insulin sensitivity.

Synergy — Vaccinium oxycoccos

Synergistic interaction of cranberry has been confirmed in combination with other polyphenol-containing taxa. In combination with Vaccinium macrocarpon, an additive enhancement of anti-adhesive activity against bacterial strains is observed due to the summation of type A proanthocyanidin content. This effect has been described in in vitro models and is associated with an increase in the concentration of active fractions in the biological environment.

Reference: Foo L.Y. et al., 2000, Proanthocyanidins of Vaccinium species, Phytochemistry, 54(2), 173–181 (https://pubmed.ncbi.nlm.nih.go...)

Potentiation of the antioxidant effect has been noted with the combined use with Camellia sinensis, which is manifested in an enhanced ability to neutralize reactive oxygen species and modulate the expression of pro-inflammatory mediators. The synergy mechanism is associated with the structural differences of flavonoids and their influence on similar signaling pathways of the cellular response to oxidative stress.

Reference: Seeram N.P., 2008, Berry fruits and polyphenols, Journal of Agricultural and Food Chemistry, 56(3), 627–629 (https://pubmed.ncbi.nlm.nih.go...)

An additional modulating effect has been described in combination with Vitis vinifera, where resveratrol and proanthocyanidins act on similar cellular targets, including endothelial cells and macrophages. This interaction is characterized by a potentiating effect on antioxidant protection and the regulation of adhesion molecule expression.

Geography of Use and Traditional Medicine — Vaccinium oxycoccos

Small cranberry traditionally grows in the northern regions of Europe, Asia, and North America, including the territories of Scandinavia, the Baltic States, Russia, Canada, and the northern states of the United States of America. Ethnobotanical sources document its use among Finno-Ugric peoples, Slavic tribes, and Native American communities. Archaeoethnobotanical data indicate the use of cranberry fruits for food and medicinal purposes as early as the medieval period in Eastern Europe.

In Slavic tradition, cranberry was used in the form of decoctions and infusions of fruits for conditions accompanied by elevated body temperature and general weakness. Fruit drinks and concentrated berry decoctions were used as a general tonic during the cold season. In the northern regions of Russia and Siberia, cranberry fruits were considered "cleansing" and were used in rituals of spring renewal, symbolizing the purification of the body and space.

Among the peoples of the Baltic States and Scandinavia, cranberry was included in fermented beverages used during the off-season period. Ethnomedical sources indicate the use of berry juice for topical application to the skin for irritations and microdamages. In Finnish folk practice, cranberry was considered the berry of the power of the swamps and was associated with the cleansing properties of natural water bodies.

In Native American traditions of North America, the fruits were used as a component of dried mixtures with meat and fats, which ensured long-term storage and was considered a strengthening product during the cold season. In some tribal practices, the berries were used in harvest thanksgiving ceremonies and in rituals associated with transitional stages of the life cycle.

Currently, cranberry continues to be used in the traditional cuisines of northern peoples, as well as in ethnomedical practices as an element of beverages, infusions, and topical herbal remedies.
