Respiratory & Lungs

Lung Detox & Smoker's Recovery

Help the lungs clear tar, mucus, and oxidative damage after smoking, vaping, or smoke exposure with mullein, NAC, mucolytic herbs, and antioxidant-rich foods.

Prevention

Key nutrients: NAC, glutathione, vitamin A, vitamin C, vitamin E, selenium, omega-3, quercetin, sulforaphane.

Eat regularly: Broccoli sprouts (sulforaphane), garlic, onion, ginger, turmeric, citrus, berries, leafy greens, green tea, wild salmon, Brazil nuts.

Steam inhalation with eucalyptus 2–3×/week, daily brisk walking to clear lower lobes, breathing exercises (Buteyko or pursed-lip), and aggressive avoidance of secondhand smoke and indoor air pollution.

Mullein

HerbTraditional use

Tea (1–2 tsp dried leaf steeped 10 min, strain through fine mesh), 2–3 cups/day — classic lung herb that loosens and expels deep mucus.

NAC (N-acetylcysteine)

OtherStrong evidence

600 mg 2–3×/day — thins mucus, regenerates glutathione, and protects lung tissue from oxidative damage. Best-studied natural agent for COPD and smoker's lung.

Lobelia

HerbTraditional use

Small doses of tincture (5–10 drops) under herbalist guidance — traditional respiratory stimulant and antispasmodic for hard, congested coughs.

⚠ Cautions: Use only in low doses with guidance — large doses cause nausea and vomiting.

Pine needle tea

HerbTraditional use

Fresh white pine needle tea (1 handful chopped needles in hot water, steep 10 min) — high in vitamin C and pinene, traditional for chest congestion.

Ivy leaf extract

HerbStrong evidence

Standardized extract (35 mg 2×/day) — clinically proven expectorant and bronchodilator; widely used in Europe for chronic cough and bronchitis.

Vitamin A (from cod liver oil)

VitaminStrong evidence

5000–10000 IU/day from cod liver oil — essential for regenerating bronchial epithelium damaged by smoke.

⚠ Cautions: Do not exceed in pregnancy without clinician oversight.

Sulforaphane (broccoli sprouts)

FoodStrong evidence

1/2 cup fresh broccoli sprouts daily or 100 mg sulforaphane extract — powerfully activates lung detox enzymes (NRF2 pathway).

Eucalyptus steam

HerbModerate evidence

5–10 drops eucalyptus oil in a bowl of hot water, towel over head, inhale 10 min — opens airways and mobilizes mucus.

A note of caution. Natural doesn't mean risk-free. Herbs and supplements can interact with medications, affect pregnancy, or worsen certain conditions. Speak with a qualified clinician before starting a new regimen, especially if you take prescriptions.
