Lavender essential oil is one of the most researched natural remedies for calming the nervous system. Clinical trials have explored its use for anxiety, sleep, pre-surgery stress, and yes—lowering heart rate. Below is a breakdown of the most trusted studies showing how lavender interacts with the cardiovascular system, including whether it can reduce heart rate or blood pressure in a measurable way.

💜 Why This Matters
The data is clear: lavender essential oil can trigger the body’s natural relaxation response. Whether used before bed, during a massage, or for anxiety management, it may help lower heart rate, reduce stress hormones, and support better heart-brain connection.
Want to try it? Keep lavender oil beside your bed and inhale it for 3–5 minutes before sleep—or massage into your chest with a carrier oil. Your nervous system may thank you.
