The throat is one of the body's primary interfaces with the external environment, and maintaining a healthy microbial balance in the oral cavity and pharynx is central to general wellbeing during periods of seasonal challenge or elevated immune demand. Harker Herbals Be Well Throat Spray combines three active ingredients — New Zealand mānuka honey, bee propolis, and the proprietary Oxifend® Throatsoother Blend — in a direct-delivery spray designed to contact the mucous membranes of the mouth and throat precisely where support is needed.
Formulated by master herbalists and manufactured in New Zealand to GMP standards, this product reflects Harker Herbals' four decades of expertise in liquid herbal medicine. All ingredients are third-party tested for heavy metals, pesticides, and authenticity before use.
Mānuka Honey — Antimicrobial Activity and Mucosal Comfort
New Zealand mānuka honey (Leptospermum scoparium) is distinguished from conventional honeys by its high concentration of methylglyoxal (MGO), a compound with well-characterised antimicrobial properties. At 86 mg per ml, the mānuka honey in this formula contributes meaningful levels of this bioactive component alongside more than 2,000 additional compounds — including phenolic acids, flavonoids, and hydrogen peroxide-generating systems — that collectively support mucosal integrity and a healthy microbial environment in the oral cavity and throat. The viscous, coating nature of honey also provides physical contact comfort to the mucosal surfaces of the pharynx.
Bee Propolis — Flavonoid-Rich Resinous Support
Propolis is a complex resinous material collected by bees from botanical sources and used within the hive for structural integrity and preservation. Its bioactivity is attributed primarily to its flavonoid and phenolic acid content — principally chrysin, pinocembrin, caffeic acid phenethyl ester (CAPE), and galangin. This formula delivers 29 mg of bee propolis tincture per ml, standardised to provide 2.7 mg of propolis flavonoids per serving. These compounds are recognised for their antioxidant properties, their support of healthy inflammatory balance, and their contribution to the body's natural antimicrobial defences. Propolis has a documented history of traditional use in supporting throat, oral, and respiratory wellness.
Oxifend® Throatsoother Blend — Clinically Researched NZ Botanical Complex
Oxifend® is a proprietary New Zealand blend of blackcurrant (Ribes nigrum) extract and polyphenol-rich grape extracts derived from Pinot Noir and Sauvignon Blanc varieties. This combination delivers a concentrated spectrum of anthocyanins, proanthocyanidins, and resveratrol-related polyphenols with well-documented antioxidant activity. The blend has been the subject of clinical investigation into its support for healthy microbial balance in the throat and its role in supporting the body's natural comfort during periods of immune challenge. The 29 mg/mL dose provides meaningful polyphenol levels that complement the mānuka honey and propolis components of the formula.
Polyphenol Synergy and Antioxidant Rationale
Antioxidants from varied botanical sources differ in their chemical structure, absorption kinetics, and tissue localisation. The combination of honey-derived phenolic acids, propolis flavonoids, and grape and blackcurrant polyphenols in this formula creates a broad-spectrum antioxidant environment in the oral and pharyngeal mucosa. During periods of heightened immune activity, reactive oxygen species generation increases; antioxidant intake from diverse polyphenol classes may help the body maintain normal cellular function under these conditions.
Format Advantage
The throat spray format bypasses systemic absorption and delivers active ingredients directly to the oral and pharyngeal tissues where they exert local effects. The 30 ml bottle size is suitable for on-the-go use and provides a concentrated supply for periods of acute need. The naturally sweet wild berry flavour is achieved using thaumatin, a plant-derived protein sweetener, with no added sugars.
