Vaccinium Macrocarpon: Natural Weapon against Various Dental and Medical Ailments
Vaccinium macrocarpon (cranberry) is a native fruit of northern America. It is a small evergreen shrub which grown in cooler climate of different parts of world. It is an abundant source of Vitamin and Minerals. It has potent health benefits which include its anti adhering property, anti oxidant property, UTI, gastrointestinal system, anti tumor effect as well as in oral diseases. It is more biocompatible and less noxious which makes it more potent therapeutic agent. This review is formed for displaying cranberry as a natural weapon against the medical and oral disease.

Biological Properties
UTI
In urinary tract infection Uropathogens enter into uninary tract, it mainly affects uninary bladder as microorganism invade via urethra. Female are more prone to UTI than male. If left untreated it can pervade towards kidney. Microorganism level crosses the threshold limit in urine it leads to Urinary Tract Infection [6]. Some of symptoms include frequency, supra pubic pain, dysuria, urgency, hematuria, nausea, cloudy urine, vomiting, delirium etc [2]. Cranberry is one of the traditional medicine which is used to treat UTI. Its extract has antibacterial activity against uropathogens i.e. Escherichia coli, Enterobacter aerogenes, Klebsiella pneumonia and Staphylococcus aureus [8]. It curtail the formation of biofilm on the uroepithelial cells [9]. It consist of proanthocyanidins which has anti clinging property, which constrain adherence of bacteria to uroepithelial cells [10], which is essential if bacteria is to cause infection [11].
Mechanism of Action
- Kinney proposed another mechanism of action that cranberry juice contains quinic acid which increases the excretion of hippuric acid in the urine which is said to have antibacterial effect, thus preventing the infection [12]. But this however is not accepted as it is not proved.
- Cranberry juice which contains fructose which prevents the adherence of fimbriated E-Coli to the uroepithelial cells [13].
- Cranberry juice may affect the concentration of Tamn- Horsfall Glycoproteins or Uromodulin in urine which hinders Escherichia coli as well other bacteria bind to the human kidney [14].
- Non-enzymatic production of nitric oxide under acidic conditions. Nitric oxide can become activated via bacterial nitrate reductase and the induction of inflammation-driven nitric oxide synthase. This in turn could potentially create a bacteriostatic environment within the urinary tract [15].
- Cranberry juice acts beneficial in preventing infection instead of treating the UTI as it has less effect on microorganism after adhesion [2].
GIT
Helicobacter pylori is a gram negative bacteria resides in the stomach and duodenum of human. It induces inflammatory reaction of the stomach mucosa which may be leads to stomach cancer, peptic ulcer, mucosa-associated lymphoid tissue lymphoma and idiopathic thrombocytopenic purpura. Growth of Helicobacter pylori was suppressed by Cranberry extract. When use in combination with other food products or probiotics it is believed to cause more elimination of the H.pylori [16]. Extract constrains the attachment of bacteria to gastric cells [17]. It is efficacious against Bacillus cereus and Clostridium perfringens.
Dissolution of the gram negative bacteria leads to release of lipopolysaccharides which is present in the outer membrane of the bacteria. This leads to cell death due to Permeability of the cell and leakage of cell content. Lipopolysaccharies from Salmonella typhimurium and Salmonella infantis releases by cranberry extract [18].
Antimicrobial property of cranberry extract is due to gallic acid which destabilizes the membrane of bacteria by chelating divalent cations [18, 19]. Biosynthesis of cell wall of Staphylococcus aureus is interrupted by the anti microbial property of cranberry extract. Cranberry extract when use in combination with β-lactam antibiotic shows synergetic effect in treating S. aureus infections [20].
Cranberry extract contains proanthocyanidins which is active in colon due to which it binds to bacterial receptor of colon and hinders its binding with uroepethelial cells and inhibit its multiplication [21].
Cardiovascular Health
Cranberry contains flavonoids which are potent antioxidant and reduces the chance of atherosclerosis. Deposition of fat, cholesterol and calcium in the arteries, due to which arteries become narrow this leads to a disease called atherosclerosis. Oxygen rich blood found difficulty in reaching other body parts which can leads to strokes and heart attacks [1].
Bones
Cranberries are the abundant source of calcium. Regular intake of cranberry juice, it enhances the strength of bones [1]. Scurvy Deficiency of Vitamin C leads to a disease called scurvy. Cranberry juice is an abundant source of Vitamin C. Regular intake of cranberry juice impede scurvy [1].
Obesity
Cranberry juice is a copious source of organic acid. Organic acid has emulsification effect on the fat accumulated. So, it’s good for obese people [1].
Anti- aging
Cranberry juice contains phytonutrients and many antioxidants. They play an important role in skin protection. Anti oxidant present in cranberry reduces free radicals which enhances its anti-aging property [1].
Anti-Oxidant
Intake of doxorubicin drug leads to cardiotoxicity by forming free radicals. The free radicals enhance the oxidative stress which causes cardiac failure is resisted by cranberry extract. Cranberry extracts are abundant source of phenoloic acid and flavonoids as these compounds have potent antioxidant effect22, they restrict oxidative process in different cells and tissues [23].
Anti-Tumor Effect
Among all beries cranberry has highest Anti oxidant property. The oxidative process associated with tumor genesis is restrained with the help of cranberry’s anthocanins antioxidant property [5]. Cranberry proanthocyanidin (PAC) treatment for human oesophageal adenocarcinoma restrains the various carcinogenic linked processes. PAC treatment increasing the response of BH3 interacting domain death antagonist, TRADD and TP73 which enhances apoptosis [24].
PAC induces restrain of ornthine decarboxylase in epithelial cells [25]. Cranberry contains Ursolic acid which restrains the growth of leukemia cell lines and lung carcinoma [26]. PAC treatment has remarkably controlling influence on cancer related biological processes and plays an important role in communicating pathways in NCI-H460 lung cancer cells. PAC has extensively remarkable and rapid apoptosis inducing effects on multiple cell cycle linked genes resulting in decreased cell multiplication and enhanced apoptosis [27].
Cranberry extracts which remarkably reduce the cell growth and escalation of oral squamous cell carcinomas. There was a sudden rise of mRNA expression in caspases-2, caspases-8, apoptosis initiator, and effector. The extract also decline cellular adhesion [28].

In prostate cancer, whole cranberry extract initiate cytotoxicity, which restrains the expression of cell cycle proteins and regression of DU145 cells through the cell cycle [29]. Proanthocyanidins restrain the expression of matrix metalloproteinase in DU145 cells and decrease translocation of NFkB p65 protein to nucleus [30] (Figure 2).
Lung Inflammation
Inflammation in lungs which is caused by influenza virus is cured effectively by the cranberries anti inflammatory property. NDM or non dialyzable material restrains influenza virus from attaching to the cells and restricts the flu infection [1].
Interactions
Few exceptions were there instead of abundant health benefits which are listed below [1].
Warfarin (Coumadin): Warfarin is an anticoagulant drug. Its action is by reducing the clot formation in the body. Those people who consume Warfarin in cardiovascular disorders should be very cautious regarding consumption of cranberries as there are more chances of bleeding. Aspirin Allergy: Cranberries are a good source of salicylic acid, aspirin also contains salicylic acid. Person consumes blood thinner they should avoid taking cranberry juice. If people are allergic to aspirin, should avoid Cranberries.
Kidney Stones: Cranberry juice contains the abundant amount of oxalate and calcium. Oxalate and calcium are of great chances of developing the calciumoxalate stones and uric acid stones in some people. People having a history of kidney stones then they should avoid consumption of the cranberry supplements or berry juice.
Dental Uses
Dental Caries: Enzymes, polysaccharides, host and bacteria comprise biofilm, whose progression and initiation leads to the oral disease [31]. In the oral environment when sucrose level is high, Streptococcus mutans initiate the genes which are liable for its virulence. Genes (gtfB, gtfC, gtfD) which are liable for the streptococcus mutans virulence decodes glucosyltransferase and formed gylycans when combine with sucrose [32]. In the existence of glucosyltransferase sucrose form glycan which imbibe to the surface. This leads to aggregation of the bacteria on the tooth surface and form bulk and structure of biofilm. After adherence of streptococcus mutans to the tooth surface leads to production of acid which results in demineralization of the enamel and it leads to dental caries.
In the plaque matrix acid is produced by bacteria which lead to acid resistant bacteria [7]. Anti-clinging property of cranberry restrains the attachment of cariogenic bacteria on the surface of tooth [33].
It restrains the bacteria from clinging on the surface of tooth which regulates oral flora but does not destroy them. Ervin I. Weiss, et al. conducted a study in which there is significant reduction in bacterial count (streptococcus mutans and total bacteria) in the volunteer’s saliva, using cranberry extract mouthwash as compared to placebo mouthwash [33].
Fungal growth
Candidiasis is fungal infection which occurs due to profound growth of the Candida albicans. A-type Cranberry proanthocyanidin (AC-PAC) diminish the attachment of C. albicans to oral epithelial cells. It also leads to great reduction in the secretion of cytokines, hence curtail inflammation. In the prevention and treatment of oral candidiasis AC-PAC can be used [34].
Perioodontal Disease: Resorption of alveolar bone is a typical hallmark of periodontal disease. Reduction in the osteoclastic activity as well as reduction in the formation of differentiated osteoclast is by the cranberry extract. It also hampers the physiology of bone matrix. In the prevention and treatment of bone loss related to inflammatory disorders such as periodontal disease cranberry extract may be used [35]. Cranberry extracts decrease the periodontopathogens induced inflammation by decreasing the inflammatory cytokines like IL-1β, IL-6, and IL-8 and TNF-α [36].
Conclusion
Unlike other medicines vaccinium macrocarpon is a natural weapon against many ailments which can be consumed regularly and also be cautious about its interactions. Cranberry extracts has tremendous health benefits by its anti adherence property and also by anti oxidant property which acts as potent alternative to the cancer treatment, UTI, Gastrointestinal system and oral disease. It helps in ameliorating the overall health and shields them from illness. Further research should be conducted in elaborating the properties of this wonder fruit.
