Why it works for Whooping Cough:
Peppermint (Mentha × piperita) is not a proven treatment or cure for whooping cough (pertussis). It may provide symptom relief for cough and upper-airway discomfort because menthol and related compounds relax airways, act as mild antitussives/expectorants, and may have some antimicrobial/anti-inflammatory activity — but there are no high-quality clinical trials showing peppermint cures or eliminates Bordetella pertussis infection. For pertussis you should follow standard medical care (antibiotics for infected people and close contacts, and urgent medical attention for infants). GOV.UK
Menthol and related constituents (the main components of peppermint oil) produce a cooling sensation, can relax bronchial smooth muscle, and act on sensory receptors in the upper airway — this can reduce the sensation of irritation and suppress cough reflexes in some settings. Studies and reviews describe peppermint’s bronchodilator, antitussive and anti-inflammatory activities in lab and some clinical contexts (mostly non-pertussis coughs). ScienceDirect
Antimicrobial/antiviral in vitro activity: peppermint extracts and essential oil show antibacterial/antiviral activity in laboratory studies against some pathogens, but in vitro activity does not mean it will treat pertussis in people. Pharmacognosy Journal
Traditional use for coughs: peppermint tea and inhalation have a long history in herbal medicine as symptomatic treatments for cough, sore throat and congestion. Reviews of herbal therapies list peppermint among teas/essential oils historically used for cough relief. Sciendo
How to use for Whooping Cough:
Peppermint tea (infusion): steep fresh or dried peppermint leaves in hot water for several minutes and sip warm to soothe throat and reduce cough tickle. No standard clinical dose; common home recipes are 1–2 tsp dried leaves (or a few fresh leaves) per cup steeped 5–10 minutes. (Used as symptomatic comfort rather than curative therapy.) Dr Farrah MD
Steam/inhalation (aromatherapy): add a few drops of peppermint essential oil to hot water and inhale steam (careful: keep a safe distance to avoid burns). Some people add peppermint (and eucalyptus/tea tree) to steam to ease congestion and breathing. Do not put undiluted essential oil directly into the nostrils or on the face of infants. Dr Farrah MD
Topical diluted rubs/INHALABLE blends: diluted peppermint oil (in a carrier like coconut or almond oil) is sometimes applied to the chest or throat for symptomatic relief. Professional aromatherapy guidance recommends strong dilution and avoiding application to infants’ chests/feet. There is no standardized clinical dosing for pertussis. naha.org
Diffusing low concentrations: using a diffuser with a small amount of peppermint oil for adults/older children in a well-ventilated room is used by some to ease breathing sensation; avoid diffusing near infants or pets. doTERRA
Scientific Evidence for Whooping Cough:
No quality clinical trials showing peppermint cures or treats pertussis. Major clinical guidance on pertussis (public health guidance, NICE/CKS) does not list peppermint or essential oils as treatments — they recommend antibiotics, supportive care and immunization. That means peppermint is not an evidence-based therapy for the infection itself. GOV.UK
Peppermint evidence exists mainly for other conditions: randomized trials exist for peppermint oil in irritable bowel syndrome and laboratory/animal work or small human studies for general cough/bronchodilation, but evidence for treating bacterial pertussis is absent. Reviews of peppermint pharmacology summarize biological activities (bronchodilator, antimicrobial in vitro, anti-inflammatory) but do not provide clinical pertussis trials. Pharmacognosy Journal
Systematic reviews / herbal cough reviews note peppermint is one of several herbs traditionally used for cough, but they emphasize limited clinical data and heterogeneity of studies (different extracts, doses, outcomes). That means we can’t conclude peppermint is clinically effective for pertussis. Sciendo
Specific Warnings for Whooping Cough:
Infants and young children: peppermint essential oil and menthol can cause serious adverse events in infants and young children (including respiratory distress). Many aromatherapy safety guides and poison control resources advise avoiding peppermint essential oil on or near infants’ chests, feet or faces and using extreme caution with inhalation around babies. Do not use peppermint oil as a home “treatment” for infant cough without medical advice. naha.org
Toxicity / ingestion risks: concentrated peppermint oil contains a high percentage of menthol; ingestion of large amounts can cause nausea, vomiting, dizziness, muscle weakness, confusion, slowed breathing and in rare cases severe toxicity. Poison control guidance warns that peppermint oil is an irritant and can be toxic in large doses. Poison Control
Topical irritation and dilution: essential oils must be diluted before topical use. Undiluted application causes skin/eye irritation or chemical burns. Professional aromatherapy guidance typically recommends low dilution ratios (e.g., 0.5–2% for topical use in adults depending on product and condition) and avoidance or very low doses in children — but exact ratios vary by guideline and product; follow reputable aromatherapy/medical advice. naha.org
Drug interactions / medical conditions: peppermint (particularly oil) can affect gastroesophageal sphincter tone and may worsen reflux in some people; menthol may interact with some medications or conditions (ask a clinician if you’re on multiple drugs or pregnant). If you have underlying lung disease, severe cough, or are taking prescription meds, check with a clinician. Pharmacognosy Journal
General Information (All Ailments)
What It Is
Peppermint is a hybrid plant derived from spearmint (Mentha spicata) and watermint (Mentha aquatica). It’s recognized for its distinctive menthol aroma and cooling sensation. In the health context, peppermint is used both as a herbal remedy and a therapeutic essential oil. It is available in several forms—fresh or dried leaves for teas, essential oil for topical or inhaled use, and extracts or capsules for oral supplementation. The active compounds in peppermint include menthol, menthone, and menthyl acetate, which are responsible for its characteristic flavor, scent, and medicinal effects.
How It Works
Peppermint’s therapeutic effects stem primarily from its volatile oils, especially menthol. These compounds interact with the body in several ways:
- Digestive System Support – Menthol helps relax the smooth muscles of the gastrointestinal (GI) tract, reducing spasms and easing the passage of gas. This action helps relieve symptoms of irritable bowel syndrome (IBS), bloating, and indigestion.
- Analgesic and Cooling Effect – When applied to the skin or inhaled, menthol activates cold-sensitive TRPM8 receptors, creating a cooling sensation that can temporarily reduce pain, itching, or tension.
- Respiratory Relief – Peppermint vapors can help open the airways by acting as a mild decongestant. Menthol may also soothe throat irritation and reduce coughing.
- Antimicrobial Properties – Peppermint oil exhibits antibacterial and antifungal activity, which may help in maintaining oral hygiene and reducing infection risk.
- Cognitive Stimulation – The aroma of peppermint can enhance alertness, concentration, and mood through its interaction with the central nervous system.
Why It’s Important
Peppermint holds significant importance in both traditional and modern medicine due to its broad therapeutic versatility. It’s valued as a natural, non-invasive option for managing digestive discomfort, tension headaches, and minor respiratory issues.
In clinical contexts, enteric-coated peppermint oil capsules are used as a complementary therapy for IBS, as they reduce gut spasms without affecting normal digestion. Peppermint aromatherapy is also popular for improving mental clarity and reducing fatigue.
Moreover, peppermint’s antimicrobial action contributes to dental health—hence its frequent use in toothpaste and mouthwash. Its accessibility, safety (when used properly), and multi-system benefits make it an integral part of herbal and holistic health practices.
Considerations
While peppermint is generally safe for most adults, there are important considerations regarding its use:
- Dosage and Form – Peppermint oil is highly concentrated; improper use can cause adverse effects. Dilution is necessary for topical use, and internal use should follow professional guidance.
- Gastroesophageal Reflux (GERD) – Peppermint can relax the lower esophageal sphincter, which may worsen heartburn or reflux symptoms.
- Children and Infants – Peppermint oil should not be applied near the faces of infants or young children, as inhaling menthol vapors may cause breathing difficulties.
- Allergic Reactions and Skin Sensitivity – Some people may experience irritation or allergic reactions when using peppermint oil on the skin. A patch test is recommended.
- Medication Interactions – Peppermint oil may interfere with certain medications, including those metabolized by the liver enzyme CYP3A4, or reduce the absorption of some drugs due to its effects on digestive motility.
- Pregnancy and Breastfeeding – Although peppermint tea is generally considered mild, concentrated forms such as oils or supplements should be used cautiously during pregnancy or lactation, ideally under medical advice.
