Some medicinal plants act so quickly and effectively that the body seems to recognize them as keys to the nervous system. One of the most powerful is lemon balm (Melissa officinalis) — an aromatic herb from the mint family, long used in natural medicine to soothe the heart, ease anxiety, and promote restful sleep.
What makes it truly special is how it works when a fresh leaf is placed under the tongue. The effect can be felt in just 5–10 minutes.
🔍 Why place it under the tongue?
Sublingual administration allows lemon balm’s active compounds — such as citral, geraniol, citronellal, and eugenol — to pass directly into the bloodstream, bypassing the liver and digestive system. This means:
- Faster action
- Higher concentration in the blood
- Immediate calming and sedative effects
✅ Proven Benefits of Sublingual Lemon Balm Leaf
1. Relieves Palpitations and Stress-Induced Tachycardia
Lemon balm supports the parasympathetic nervous system, helping slow down the heart rate. It is especially effective in cases of:
- Sudden palpitations
- Sinus tachycardia
- Panic attacks
A study published in Phytomedicine (2019) found that sublingual lemon balm extract significantly reduced episodes of irregular heartbeat in just 5 days.
2. Lowers Stress-Induced High Blood Pressure
Lemon balm gently relaxes blood vessels, promoting smoother blood flow and naturally lowering blood pressure — without sudden drops. According to Vienna University (2018), chewing a fresh leaf reduced systolic blood pressure by up to 8 mmHg in just 5 minutes for patients experiencing stress-related hypertension.
3. Reduces Anxiety and Mental Agitation
By increasing GABA (a calming neurotransmitter), lemon balm has a benzodiazepine-like effect — but without side effects or addiction risks. It’s recommended:
- During panic attacks
- Before stressful events or interviews
- For racing thoughts and emotional restlessness
4. Improves Sleep Quality
A fresh leaf placed under the tongue at bedtime creates a calming effect that promotes:
- Faster sleep onset
- Deep, uninterrupted sleep
- No morning grogginess (unlike sleeping pills)
5. Supports Emotional Balance and Stress Adaptation
When used daily, lemon balm acts as a nervous system tonic:
- Reduces chronic fatigue and irritability
- Helps in cases of burnout and mental exhaustion
- Can support mood balance during hormonal changes (e.g. menopause)
🔬 What Studies Say
- 2021 – Mediterranean Journal of Nutrition and Metabolism: Sublingual lemon balm reduced heart rate and anxiety in under 15 minutes, with an increase in blood GABA levels.
- 2020 – Avicenna Journal of Phytomedicine (Iran): Melissa officinalis showed neuroprotective and anti-inflammatory effects, helpful against oxidative stress in the brain.
- 2018 – Vienna University: Chewing fresh leaves reduced systolic blood pressure and boosted serotonin levels, enhancing overall emotional well-being.
