Several herbal teas can help your body manage fever and chills, with peppermint, elderflower, ginger, and yarrow among the most effective. These herbs work by promoting sweating, easing inflammation, and keeping you hydrated while your immune system does its job. None of them replace fever-reducing medication when you truly need it, but as a comfort measure and hydration strategy, the right tea can make a real difference in how you feel.
How Tea Helps During a Fever
A fever is your body’s way of fighting infection, and chills are the shivering response your muscles produce to generate the heat that raises your temperature. Herbal teas support this process in a few ways. First, warm fluids replace the water you lose through sweating and increased metabolism. Second, certain herbs are classified as “diaphoretics,” meaning they promote perspiration and enhance blood flow to the skin’s surface. This helps your body regulate its temperature more efficiently rather than trapping heat internally. Third, some herbs reduce the inflammatory compounds that make you feel achy and miserable during a fever.
Peppermint Tea
Peppermint is one of the most accessible and effective teas for fever and chills. Menthol, its active compound, increases blood flow and creates a cooling sensation that can ease the uncomfortable heat-then-cold cycling of a fever. It also helps open nasal passages if congestion is part of the picture. On its own, peppermint tea is pleasant enough to drink repeatedly throughout the day, which matters when you need to stay hydrated.
Elderflower and Elderberry Tea
Elderflower has been used for centuries as a diaphoretic herb, gently encouraging sweating to help break a fever. Elderberry, from the same plant, has stronger evidence for shortening illness. In a randomized, placebo-controlled trial of air travelers, those taking elderberry experienced cold episodes that lasted an average of 4.75 days compared to 6.88 days in the placebo group. Their symptom severity scores were also significantly lower (21 vs. 34). While this study used a concentrated supplement rather than tea, brewing dried elderberries or elderflowers into a strong tea delivers some of the same immune-supporting compounds.
You can find dried elderflower on its own or blended into “cold care” tea bags at most health food stores. For elderberry, look for dried berries or pre-made syrups you can stir into hot water. Never use raw, uncooked elderberries, as they contain compounds that can cause nausea.
Ginger Tea
Ginger is a warming herb, which sounds counterintuitive when you already have a fever, but that warmth promotes circulation and sweating that helps your body cool down. Ginger also inhibits cyclooxygenase, the same enzyme targeted by common pain relievers, which means it can reduce some of the inflammatory compounds responsible for body aches and that general “hit by a truck” feeling. A large systematic review of 109 randomized controlled trials found consistent support for ginger’s anti-inflammatory effects.
Fresh ginger tea is simple to make: slice a thumb-sized piece of ginger root, simmer it in two cups of water for 10 minutes, then strain. Add honey and lemon if you like. The spicy bite can also soothe a sore throat temporarily.
The Classic Fever Tea Blend
Herbalists have long relied on a specific three-herb combination for fevers: equal parts dried yarrow, elderflower, and peppermint. This blend, sometimes called “Gypsy Cold Care,” combines yarrow’s strong diaphoretic action with elderflower’s immune support and peppermint’s cooling relief. To make it, pour two cups of near-boiling water over two tablespoons of the mixed herbs, cover, and steep for 10 to 15 minutes. Strain and add honey or maple syrup, because this blend doesn’t taste great on its own.
The traditional dosing is about a quarter cup every hour while awake. Some herbalists expand the formula to include ginger, linden flower, or boneset for added effect. The goal is to drink it steadily, then bundle up under blankets and let the sweating happen. This old-fashioned approach helps stimulate immune function while easing aches and pains.
Chamomile Tea
Chamomile won’t directly lower a fever, but it plays a supporting role. Its mild sedative quality helps you rest, and rest is arguably the most important thing you can do when fighting an infection. If your fever and chills are keeping you from sleeping, a cup of chamomile before bed can help you relax enough to get the recovery time your body needs. It’s also one of the gentlest options for children.
Getting the Most From Your Tea
How you prepare herbal tea matters more than you might think. A quick two-minute steep won’t extract enough of the active compounds to be useful. For medicinal purposes, steep your herbs for 10 to 15 minutes in water that’s just off a full boil, around 208°F. Covering your mug or teapot while steeping is important because it traps the volatile oils (especially menthol from peppermint) that would otherwise evaporate into the air instead of staying in your cup.
Use about one tablespoon of dried herbs per cup, or two tea bags if you’re using commercial products. Drink three to five cups spread throughout the day. Herbal tea is caffeine-free, so it won’t interfere with the rest you need, and it hydrates just as effectively as water while delivering additional therapeutic compounds.
Teas for Children With Fever
Chamomile, peppermint, ginger, and fennel teas are generally considered safe for children without underlying health conditions. Stick to one to three cups per day for toddlers and young children, as too much fluid relative to their body size can dilute electrolytes. Keep the tea weak, using half the amount of herbs you’d use for an adult cup.
One important rule: never add honey to tea for a child under 12 months old due to the risk of botulism. For older toddlers and children, a small amount of honey can make the tea more appealing and adds its own mild soothing properties for sore throats. If you’re unsure about giving herbal tea to a young child, especially one under two, check with your pediatrician first.
When Tea Isn’t Enough
Herbal tea is a comfort measure, not a treatment for serious illness. For adults, a temperature of 103°F (39.4°C) or higher warrants a call to your doctor. Seek immediate attention if fever comes with a stiff neck, rash, confusion, persistent vomiting, difficulty breathing, or seizures.
For children, the thresholds are lower. Any infant under three months with a rectal temperature of 100.4°F or higher needs medical evaluation. Between three and six months, the concern threshold is 102°F or any fever paired with unusual irritability or sluggishness. For children between seven months and two years, a fever above 102°F that lasts more than a day without other obvious cold symptoms is worth a call. A fever-related seizure lasting more than five minutes is a 911 situation regardless of age.
