Pleurisy Root is a native North American plant with bright orange flowers, found growing across eastern and central North America. The root has been a cornerstone of Indigenous American herbal medicine for generations, prized specifically for its ability to ease painful breathing and chest conditions. It gets its common name directly from its historical use treating pleurisy — a painful inflammation of the lining around the lungs.

Pleurisy Root is thought to work by reducing inflammation in the lung lining and airways, helping to loosen and move mucus out of the respiratory tract, and gently supporting lymphatic drainage in the chest. Its flavonoid compounds, particularly quercetin, have well-documented anti-inflammatory properties that may calm irritated tissue in the pleura and bronchial passages. The root also appears to have a mild diaphoretic effect — meaning it can promote sweating — which traditional healers used to help break fevers during respiratory illness.

Tincture (alcohol extract) is the most commonly available form and allows for precise dosing. Traditional use involved decoctions made from dried root boiled in water. Capsules of powdered root are convenient but may vary in potency across brands. Tea can be made from dried root, though the flavor is quite bitter. Always source from reputable suppliers, as wild harvesting has put some wild populations under pressure.

• Pleurisy and chest pain
• Bronchitis
• Chest congestion and mucus
• Respiratory infections
• Fever with chest symptoms
• Dry, painful cough
• Lung inflammation
• Lymphatic congestion in the chest

• Quercetin-rich foods (onions, apples, capers) — Quercetin is one of Pleurisy Root's key active flavonoids — eating foods high in quercetin supports the same anti-inflammatory pathways in the lungs and airways.
• Ginger — Ginger shares Pleurisy Root's anti-inflammatory and expectorant properties, and is a well-documented respiratory soother — a natural dietary complement.
• Horseradish — Horseradish is a powerful natural expectorant that helps clear mucus from the airways, supporting the same chest-clearing action Pleurisy Root is used for.
• Garlic — Garlic has antimicrobial and anti-inflammatory properties that support respiratory health and immune defense during infections — complementing Pleurisy Root's traditional role in acute respiratory illness.
• Thyme — Thyme is a culinary herb with well-documented expectorant and bronchospasmolytic properties, making it a natural dietary ally for respiratory congestion and bronchitis.

• Nausea (especially at higher doses)
• Vomiting
• Diarrhea
• Dizziness
• Potential cardiac effects at very high doses due to glycoside content
• Not safe during pregnancy — may stimulate uterine contractions

• Recommended daily: Tincture (1:5): 2–4 mL up to three times daily. Dried root decoction: 1–2 grams of dried root per cup, up to three times daily. Capsules: follow manufacturer guidance, typically 500–1000 mg per dose.
• Best time of day: Can be taken at any time; traditionally given during acute illness every 4–6 hours while symptoms are active.
• With or without food: Taking with food or after meals is recommended to reduce the chance of nausea, which is more likely on an empty stomach.
• Time to effect: Acute symptom relief may begin within 1–3 days; full respiratory benefit typically over 1–2 weeks of consistent use.
• How long to take it: Intended for short-term acute use (1–3 weeks during active respiratory illness). Not traditionally used as a long-term daily supplement. Discontinue once symptoms resolve and consult a healthcare provider if symptoms persist beyond 2 weeks.
