Harker Herbals, Immune Tonic, 500ml Description Harker Herbals Immune Tonic is a potent herbal liquid formula combining traditional immune-supporting botanicals with a carefully selected blend of antimicrobial and warming essential oils. At the heart of the formula is Echinacea Purpurea Root — one of the most extensively researched herbs in traditional Western herbalism for immune support — combined with Vervain, Yellow Dock Root, and Clove Buds. Kumarahou, a native New Zealand plant with well-established antimicrobial and anti-inflammatory properties, adds a distinctly local dimension to the formula, while Cayenne Pepper and Ginger provide circulatory stimulation to help drive active constituents to where they're needed. Licorice Root and Iodine round out the active ingredients, with Licorice contributing anti-inflammatory and antimicrobial support and Iodine providing a trace mineral with recognised roles in immune function. The essential oil blend of Aniseed, Clove Bud, Frankincense, and Cinnamon Bark contributes additional antimicrobial and anti-inflammatory properties. Delivered in the brand's signature base of Vegetable Glycerine, Irish Moss, Jojoba Oil, Celtic Sea Salt, Citric Acid, and Water, this is a strong, medicinal-tasting tonic in the classic Malcolm Harker tradition — best taken straight or added to warm water.
