Lavender is one of the most versatile essential oils—and a gentle favorite among those with COPD. Its calming properties may help reduce stress-induced breathlessness and promote more restful sleep, both of which are vital for managing respiratory health. Some people also find that diffusing lavender helps ease tightness in the chest associated with anxiety or tension. Plant Therapy’s lavender is steam-distilled from Lavandula angustifolia flowers and is GC/MS-tested to ensure purity and therapeutic quality, with results available for every batch.
