A chronic cough is defined medically as one that persists for eight weeks or longer in adults. It is among the most common reasons people seek medical advice, and its causes are remarkably varied: post-nasal drip from allergic rhinitis or sinusitis, asthma and airway hyperreactivity, gastro-oesophageal reflux irritating the larynx, residual airway inflammation after a respiratory infection, smoking-related airway damage, ACE inhibitor medication, and chronic obstructive pulmonary disease are all frequent culprits. In many cases, more than one factor is present simultaneously.
The experience of a persistent cough is more debilitating than it might sound to someone who has not had one. The constant irritation and reflex disrupts sleep, strains the muscles of the chest and abdomen, causes social embarrassment, and generates a persistent sense of vulnerability and discomfort that erodes quality of life. When the cause is identified and treated, the cough usually resolves, but the airway inflammation and mucosal irritation that sustain the cough reflex often need direct support to settle fully, even after the underlying trigger has been addressed.
Please consult your GP before beginning this programme if you have not already investigated the cause of your chronic cough. A persistent cough always warrants medical assessment to identify or exclude serious underlying causes. This programme provides nutritional support for the airways and immune system alongside whatever care your doctor has recommended and is not a substitute for that investigation or treatment.
The programme runs for thirty days. It works across three interconnected areas: soothing and reducing the inflammation of the airways that sustains the cough reflex, supporting the immune system that may be contributing to or struggling with an infectious component, and maintaining the gut-lung axis that links intestinal health to respiratory immune regulation.
Soothing the Airways and Reducing Inflammation
These three products work directly on the inflammatory and mucosal environment of the airways, addressing the irritation and swelling that keep the cough reflex active long after the original trigger has resolved.
Coral Licorice Root provides deglycyrrhizinated licorice root extract alongside ginger. DGL licorice is one of the most well-established botanical remedies for respiratory mucosa support: it stimulates the production of the protective mucus layer that coats and soothes the airway lining, reduces the inflammatory signalling at the mucosal surface that maintains airway irritation, and has direct bronchospasmolytic properties that ease the involuntary cough reflex. Its anti-inflammatory mechanism works through inhibition of the same pathways that are active in chronic airway inflammation, without the blood pressure-raising effects of non-DGL licorice. Ginger complements this action with warming, anti-spasmodic, and circulatory effects on the airway tissue. Take one capsule twice daily with food.
Coral-Mine maintains the hydration of the airway mucosa throughout the programme. The mucosal lining of the airways is a water-rich tissue, and adequate systemic hydration is one of the most direct and underappreciated contributors to mucosal health. When the body is even mildly dehydrated, airway secretions become thicker and more tenacious, impairing the mucociliary clearance that normally sweeps irritants out of the airways and triggering additional cough. Coral-Mine water also helps to maintain the mildly alkaline internal pH that reduces airway reactivity and inflammatory tone. Drop one sachet into 1.5 litres of water and sip throughout the day between meals.
Omega-3 TG provides EPA and DHA omega-3 fatty acids in triglyceride form for optimal absorption. Omega-3 fatty acids reduce systemic and airway inflammation through the prostaglandin pathway, are incorporated into the lipid component of airway epithelial cell membranes, and support the immune regulation that determines how reactive the airways are to ongoing triggers. Research in airway conditions has associated higher omega-3 intake with reduced airway hyperreactivity and improved respiratory symptom scores. Take one capsule three times daily with food.
Immune and Antimicrobial Support
Chronic cough often has an infectious or post-infectious component, either as the original trigger or as a maintained vulnerability to repeated respiratory infections that keep the airway irritation cycling. These two products support the immune system’s capacity to manage this component.
Coral Cat’s Claw provides bark extract from Uncaria tomentosa, commonly known as cat’s claw, a Peruvian vine with a long history of traditional use in respiratory and immune conditions. Its active oxindole alkaloids have well-documented anti-inflammatory, antiviral, and immune-modulating properties. Cat’s claw supports the immune system’s capacity to respond to respiratory pathogens, helps to reduce the chronic low-grade inflammation that sustains airway irritability, and has been used in traditional medicine for conditions involving persistent respiratory inflammation and immune depletion. Take one capsule three times daily with food.
Garlic Extract provides concentrated allicin-releasing garlic compounds with potent antibacterial, antiviral, and antifungal properties. Garlic has direct activity against the respiratory pathogens most commonly associated with infectious cough, and its mucolytic properties help to thin and loosen the airway secretions that can trigger cough in people with post-nasal drip or residual bronchial mucus from a past infection. It also stimulates natural killer cell activity, one of the immune system’s primary mechanisms for identifying and clearing virally infected respiratory cells. Take one capsule three times daily with food.
Gut-Lung Axis Support
The connection between gut microbiome health and respiratory immune regulation is increasingly well understood. The gut-associated lymphatic tissue represents the largest component of the immune system in the body, and its composition and health directly influence the immune responses that determine airway reactivity and susceptibility to respiratory infections.
Super Flora provides Lactobacillus acidophilus and Bifidobacterium Longum probiotic strains that normalise gut flora and support systemic immune regulation through the gut-lung axis. In people with chronic respiratory conditions, probiotic supplementation has been associated with reduced frequency of respiratory infections, modulated allergic immune responses, and improvements in respiratory symptom burden. A healthy gut microbiome creates a less reactive immune environment throughout the body, including in the airways. Take one capsule once or twice daily before food.
Lifestyle and Environmental Recommendations
Alongside the programme, a few consistent habits make a meaningful difference to chronic cough. Identify and reduce exposure to known airway irritants: cigarette smoke, both active and passive, is the most damaging and should be avoided entirely. Dust, mould, pet dander, and strong fragrances are common triggers worth evaluating. Keep indoor air humid, particularly in winter when central heating dries the air significantly, as dry air directly irritates the respiratory mucosa.
Practice nasal breathing rather than mouth breathing wherever possible, as the nose filters, warms, and humidifies air before it reaches the airways, reducing direct irritant exposure. Steam inhalation with warm water and optionally a few drops of eucalyptus oil provides temporary relief for airway irritation and helps to loosen secretions. Elevate the head of your bed by a few centimetres if reflux is suspected as a contributing factor, as nighttime acid reflux is one of the most common unrecognised causes of chronic cough.
Please consult your GP if your cough is not improving after the programme, if you develop new symptoms, or if you cough up blood at any point. If you would like to discuss whether this programme is right for your situation, please reach out through the contact page.
Frequently Asked Questions
Do I need all six products?
Coral Licorice Root is the most directly targeted supplement for chronic cough and the one I would always start with, as its mucosal-soothing and anti-spasmodic effects address the cough reflex most specifically. Coral-Mine provides the daily hydration foundation that all airway health depends on. Garlic Extract and Coral Cat’s Claw together cover the immune and antimicrobial dimensions. Omega-3 TG reduces the systemic inflammatory burden on the airways. Super Flora addresses the gut-lung immune connection that is so often overlooked in respiratory conditions. All six work together most effectively but can be introduced progressively.

How long before I notice any improvement in my cough?
Most people notice some reduction in the frequency and severity of coughing within the first ten to fourteen days, particularly as the Coral Licorice Root and Coral-Mine hydration begin to soothe and settle the airway mucosa. The immune and anti-inflammatory effects of the other products build over the full thirty days. If your cough has been present for several months, a second course after a short break may be needed to achieve the most complete result.
My GP said my chronic cough is caused by acid reflux. Is this programme still relevant?
Yes, and several elements of the programme are particularly useful for reflux-related cough. Coral-Mine’s alkalising effect helps to moderate the acid burden on the oesophageal and laryngeal tissue. Coral Licorice Root’s mucosal soothing properties are directly relevant to the irritation of the throat and larynx caused by reflux. The broader anti-inflammatory support of Omega-3 TG and Super Flora helps to reduce the tissue reactivity that makes the airway more sensitive to acid exposure. Please continue with any prescribed reflux treatment alongside this programme and discuss it with your GP.
Can I use this programme alongside prescribed cough medication or inhalers?
Please discuss every supplement in this programme with your GP before starting if you are on prescribed medication for your cough or any underlying respiratory condition. Most of the supplements here are generally well tolerated alongside standard medications, but your doctor needs to know the full picture of what you are taking to advise you appropriately and safely.
