Black beetroot juice: therapeutic characteristics, application, and contraindications

Research by ethnopharmacologists has shown that extract of black beans has antibacterial and anti-viral properties. Black beans flowers contain flavonoids, phenolic acids, triterpenes, and mucus. They act as an anti-inflammatory agent, encountering and assisting in the removal of secretions from the bladder. They affect the walls of the capillary vessels, improving their elasticity.

European elderberry (Sambucus nigra) serves as a valuable botanical resource in both cosmetic care and natural health support. Infusions prepared from its flower clusters and berries demonstrate beneficial effects in treating urinary tract disorders and constitute an essential component of detoxification regimens. Herbal pharmacies and specialty stores offer a range of elderberry-based preparations, including herbal blends with expectorant and soothing properties for dry coughs, remedies for regulating bowel function, ointments to support psoriasis management, and formulations used during upper respiratory infections. The high vitamin C content—which fortifies connective tissue integrity and stimulates collagen fiber production—makes elderberry juice particularly recommended for individuals combating cellulite, with regular consumption advised alongside massages using elderberry seed oil. Due to its gentle laxative properties, elderberry extract frequently appears in weight management supplements. The plant’s anti-inflammatory characteristics are further utilized in oral rinses for throat and mouth infections, as well as in eye compresses for conjunctivitis. Individuals with acne-prone skin may employ aqueous flower extracts as a calming facial tonic to reduce inflammatory lesions and blemishes.

While the overwhelming majority of online resources and published literature suggest that black elderberry juice is universally safe for individuals aged two and above—with no listed contraindications—this broad claim requires nuanced consideration, as critical exceptions and usage guidelines exist to prevent adverse health effects. All components of the *Sambucus nigra* plant, including its flowers and berries, contain cytotoxic glycosides—specifically sambunigrin and sambucina—which exhibit toxic properties when consumed in excessive quantities. The primary method for neutralizing these compounds involves thermal processing: boiling without a lid, simmering, or heat exposure effectively decomposes their hazardous structures. Consuming raw, unripe berries directly from the shrub remains the most common cause of poisoning incidents. Clinical manifestations of toxicity may include generalized weakness, tachycardia, respiratory distress (dyspnea and irregular breathing patterns), as well as neurological symptoms such as headaches, vertigo, nausea, vomiting, and diarrhea. Immediate medical intervention is imperative upon observing these signs, including induced emesis and preparation for potential gastric lavage in a hospital setting. Preparing elderberry juice at home is a straightforward process: the berries are briefly blanched, then crushed into a pulp and strained through cheesecloth. The resulting liquid is combined with honey in a 1:10 ratio and stored in opaque, airtight bottles. The recommended dosage is two to three daily servings of 200 ml of diluted juice (50 g of concentrate per glass of warm water), particularly during viral infections, digestive disorders, or neuropathic pain episodes. Historically, this extract was regarded as a panacea for nearly all ailments; contemporary use emphasizes its immunomodulatory benefits. Although the retail price of pre-made juice may seem prohibitive, the low daily intake requirement renders it a cost-effective, health-promoting expenditure over time.
