Warm herbal teas may help relieve congestion, soothe sore throats, support hydration and provide compounds with antioxidant or immune-supporting properties, although certain herbs require caution and tea should not replace medical treatment when symptoms are severe.

A steaming cup of tea will not cure a cold, but several commonly used herbal varieties may make the illness easier to tolerate by helping with congestion, throat irritation, nausea, hydration and other symptoms.
Ginger, peppermint, chamomile, echinacea and elderberry are among the herbs most frequently associated with cold and influenza support in traditional medicine and published research. Their potential benefits differ considerably, ranging from the simple effects of drinking warm fluids to antioxidant activity and compounds that have been studied for their effects on immune and respiratory health.
An overview published by Paleohacks and summarized by NaturalNews.com examined herbs, vitamins and foods commonly used to support immune function, presenting them as natural alternatives to conventional pharmaceutical approaches that the source criticized as frequently profit-driven and associated with side effects.
The most immediate benefit of tea during a respiratory illness may have little to do with any individual herb. The combination of fluid and heat can itself provide relief.
NaturalNews.com reported that a hot beverage may help open a congested nose, calm a sore throat and ease a headache. Tea also contributes to fluid intake at a time when a person may be losing more water than usual through sweating or a persistent runny nose. Dehydration can further strain the body during illness and may interfere with normal immune function.
“There are few things as comforting as drinking a hot cup of tea when you’re feeling under the weather,” NaturalNews.com stated.
Ginger and Peppermint Target Different Symptoms
Ginger has a particularly long history as a medicinal food and remains widely used for digestive discomfort and nausea.
Earl L. Mindell and Virginia Hopkins wrote in “Bottom Lines Prescription Alternatives” that ginger capsules or ginger tea may be used for nausea and gas. Ginger’s medicinal history extends at least as far back as Chinese writings from the 1st century BC, while modern research has continued examining its biological properties, according to NaturalNews.com.
Its warming quality and traditional use for throat irritation also make ginger tea a common choice during respiratory illnesses.
Peppermint is used somewhat differently. It is frequently associated with respiratory comfort and relief of congestion.
“The Survival Medicine Handbook” includes peppermint among several herbs used for congestion, alongside stinging nettle, licorice root, anise, cayenne pepper and sage. Laura Harris has also identified both ginger and peppermint teas as preparations used for specific wellness purposes.
For someone dealing with a cold, choosing between the two may therefore depend largely on the dominant symptoms. Ginger may be more useful when nausea or stomach discomfort accompanies an illness, while peppermint is commonly selected when nasal congestion is the bigger problem.
Chamomile Offers Antioxidant Compounds
Chamomile is best known as a calming evening beverage, but the flowers also contain compounds that have attracted attention from researchers.
A study published in the Journal of the Science of Food and Agriculture found antioxidant activity in chamomile flower extracts. The research also examined water and alcohol extracts of anise and dill seeds and found antioxidant activity in those plants as well.
Antioxidants help counter oxidative damage caused by unstable molecules in the body, although evidence of antioxidant activity in laboratory testing does not by itself establish that chamomile can prevent or cure a respiratory infection.
Other plant compounds may also play protective roles. Research published in the Journal of Food Composition and Analysis has described secondary metabolites such as resveratrol in red grapes and quercetin in onions as having protective effects against environmental pathogens.
Those findings help explain why researchers continue investigating the chemical compounds in herbs and foods rather than viewing herbal tea solely as a source of warmth and hydration.
Echinacea and Elderberry Studied for Immune and Respiratory Support
Echinacea and elderberry occupy a different place in the discussion because both have been studied specifically in connection with respiratory illness or immune function.
NaturalNews.com included elderberry among herbs recommended by experts for strengthening immune defenses.
Mercola.com has also reported that elderberry can reduce upper respiratory symptoms.
Echinacea has undergone experimental research involving rhinoviruses, one of the most common causes of the common cold. “Medical Toxicology of Natural Substances” references trials involving Echinacea angustifolia and experimental rhinovirus infections.
The existence of such studies does not mean every echinacea or elderberry product will produce the same results. Herbal preparations can differ considerably in concentration, species, processing and dosage, making direct comparisons difficult.
Those differences are one reason herbal remedies are better viewed as possible supportive measures rather than guaranteed treatments.
Warm Fluids May Matter as Much as the Herb
For ordinary cold symptoms, the simplest explanation for some of tea’s benefits is also one of the strongest: warm liquids can feel soothing and help maintain hydration.
Heat and steam from tea may temporarily loosen nasal congestion, while swallowing warm liquid can soothe an irritated throat. Regular drinking also helps replace fluids lost during illness.
Traditional herbal preparations sometimes combine several ingredients to address multiple symptoms at once.
“Herbal Antivirals,” for example, includes a preparation combining ginger, cider, lemon and turmeric. The ingredients are placed in a saucepan and heated until bubbles begin forming along the edge, then allowed to steep for approximately five minutes before the mixture is strained and served.
Such combinations draw on several longstanding culinary and herbal traditions, though their use does not establish that they can eliminate the virus responsible for an illness.
How Herbal Tea Is Prepared Can Matter
A standard herbal infusion can be made with relatively simple preparation.
Barrie R. Cassileth writes in “The Alternative Medicine Handbook” that herbal tea can be prepared by placing 1 to 2 teaspoons of dried, finely chopped leaves into one cup of boiling water, allowing the mixture to steep for 10 minutes and then straining it before drinking.
The appropriate preparation can vary by herb. Leaves, flowers, roots and bark release their compounds differently, and concentrated supplements or extracts may expose the body to substantially larger amounts than an ordinary cup of tea.
That distinction becomes important because natural does not automatically mean risk-free.
Licorice Root, Echinacea and Other Herbs Carry Precautions
Several herbs commonly included in cold and respiratory preparations can interact with medications or create risks for people with particular medical conditions.
Licorice root deserves special attention.
Abigail Gehring wrote in “The Homesteading Handbook” that taking licorice root together with diuretics may cause potassium levels to fall dangerously low. People with heart disease or high blood pressure should also use caution with licorice root.
Pregnancy presents another concern. Large quantities of licorice root may contribute to preterm labor, according to Gehring.
Echinacea also is not appropriate for everyone.
Sari Harrar writes in “The Woman’s Book of Healing Herbs” that people with autoimmune conditions, including lupus, tuberculosis or multiple sclerosis, should not take echinacea. The herb should also be avoided by people allergic to plants in the daisy family.
People experimenting with wild herbs or mushrooms face additional concerns because identification, potency and toxicity can be unpredictable. Guidance on wild plants has recommended beginning with a small amount and watching for adverse reactions for several hours because some species or preparations can be toxic.
Pregnant women, people with chronic illnesses and anyone taking prescription medications may therefore need to consult a physician or pharmacist before regularly using medicinal herbs.
Product Quality Can Also Affect Safety
The safety of herbal tea depends not only on the plant itself but also on how the product was grown, processed and manufactured.
In May 2024, Health Ranger Mike Adams reported on the recall of nearly 1 million bags of Yogi’s Organic Immune Support Tea after pesticide residues were detected in the product.
The incident illustrates a separate issue from the biological effects of an herb: even a commonly consumed plant can present concerns if a commercial product contains contaminants.
Consumers using herbal teas regularly may want to pay attention to recalls, ingredient labels and the reputation and testing practices of manufacturers.
Tea Can Support Comfort, but It Is Not a Substitute for Medical Care
Cold symptoms often resolve without intensive treatment, making hydration, rest and symptom relief the primary focus for many people.
Tea can fit naturally into that approach. Ginger may help when nausea is present, peppermint may offer relief from congestion, chamomile supplies antioxidant compounds, and echinacea and elderberry have been investigated for their possible roles in respiratory and immune health.
At the same time, evidence varies considerably from one herb to another, and none should be regarded as a substitute for appropriate medical treatment.
“Natural Remedies” describes natural approaches as supporting rather than suppressing the body’s own response to illness, but it also recommends contacting a physician when body temperature exceeds 103 degrees Fahrenheit or when a fever lasts longer than three days.
Persistent, worsening or severe symptoms also warrant medical evaluation.
For most otherwise healthy adults with an uncomplicated cold, the clearest benefits of tea remain straightforward: warmth can soothe irritated airways, fluids can help prevent dehydration, and individual herbs may provide additional symptom-specific effects.
Used appropriately and with attention to medication interactions and medical conditions, herbal tea can serve as a simple supportive measure while the body recovers.
