Certain leaves from medicinal plants have such powerful therapeutic properties that they act on the nervous and cardiovascular systems in just a few minutes. One of the most effective is lemon balm leaf (Melissa officinalis), an aromatic plant frequently used in phytotherapy for its calming effects. When used sublingually, lemon balm acts quickly, being absorbed through the oral mucosa directly into the bloodstream, without first passing through the liver. This allows it to influence the central nervous system and heart functions almost instantly.
Why Place the Leaf Under the Tongue?
The answer lies in the absorption method of the active substances. Placed under the tongue, the leaf releases volatile compounds such as citral, geraniol, citronellal, and eugenol, which quickly enter the bloodstream. These interact with GABA receptors, having a rapid sedative and anxiolytic effect. Fresh lemon balm leaves are ideal in this form, as they contain high concentrations of essential oils.
Benefits:
1. Calms Tachycardia and Palpitations
Lemon balm leaves contain compounds that modulate the activity of the parasympathetic nervous system. This leads to a decrease in heart rate, especially in cases of anxiety or stress. The effect is faster when the leaf is placed under the tongue, as the active substances are not degraded by gastric juices. People suffering from palpitations associated with panic attacks have reported relief within a few minutes. Studies show that sublingual administration of lemon balm has antiarrhythmic potential in mild cases.
2. Reduces Blood Pressure Caused by Stress
Lemon balm has a mild vasodilatory effect, promoting relaxation of the vascular walls. This allows for smoother blood circulation, which reduces blood pressure. In agitated, tense, or continuously stressed individuals, blood pressure values can decrease within just 10-15 minutes. The action is natural and does not produce sudden hypotensive effects, making it safer than some medications. It is especially indicated in cases of reactive hypertension.
3. Reduces Anxiety and Inner Agitation
By influencing GABA receptors, lemon balm leaves have an effect similar to benzodiazepines, but without the risk of dependence. Individuals who experience constant tension, inexplicable nervousness, or racing thoughts can benefit from this remedy. Placing it under the tongue allows for a calming effect to set in within 5-10 minutes. It can be successfully used during panic attacks or before stressful events. It is considered one of the safest plants with calming effects.
4. Improves Sleep Quality
Even a single leaf chewed in the evening and held under the tongue for a few minutes can induce a state of relaxation conducive to sleep. Lemon balm helps reduce heart rate and calm thoughts before bedtime. Its mild sedative effect promotes deep, uninterrupted sleep. It is suitable for individuals who frequently wake up during the night or who suffer from insomnia caused by worries. Unlike sleeping pills, it does not cause drowsiness during the day.
5. Supports Emotional Balance During Demanding Periods
During periods of fatigue, overwork, or stressful events, lemon balm leaves help restore a state of balance. The plant has a tonic effect on the nervous system, allowing for more effective management of emotions. It can be used every morning with a fresh leaf under the tongue for a calmer overall state. The effect is cumulative, increasing in intensity after a few days of use. It also helps in cases of hormonal changes that affect mood (e.g., menopause).
Studies and Research Explained in a Minimum of 10 Sentences:
A study published in Mediterranean Journal of Nutrition and Metabolism (2021) evaluated the effects of lemon balm extract administration on heart rate and anxiety states in 80 patients. The results showed that participants who received lemon balm had a significant reduction in heart palpitations and anxiety symptoms compared to the placebo group. The effect set in in less than 15 minutes in the case of sublingual administration. An increase in GABA levels in the blood was also observed, explaining the anxiolytic action mechanism. Researchers concluded that sublingual administration is 2-3 times more effective than oral administration, as it avoids hepatic metabolism.
Another study published in Phytomedicine (2019), conducted on a group of 45 patients with sinus tachycardia, showed that daily administration of lemon balm extract for 2 weeks significantly reduced episodes of irregular heartbeats. The plants were provided in the form of sublingual tablets, and the results were evident within the first 5 days. Patients also reported an improvement in sleep quality and concentration. The effect persisted for several days after stopping treatment, suggesting a general regulatory action.
Additionally, in an experiment conducted at the University of Vienna (2018), it was observed that simply chewing fresh lemon balm leaves for 3-5 minutes resulted in a measurable reduction in systolic blood pressure by up to 8 mmHg. This effect was more pronounced in individuals with elevated blood pressure due to stress, compared to those with chronic hypertension. The authors considered that essential oils play a key role in this rapid effect. Furthermore, sublingual absorption was responsible for an immediate increase in serotonin levels.
Moreover, a study conducted in Iran (2020), published in Avicenna Journal of Phytomedicine, showed that Melissa officinalis also has neuroprotective potential, being helpful in preventing neuronal degeneration caused by oxidative stress. Sublingual administration was correlated with a significant reduction in inflammatory markers in the brain. This supports its use not only for anxiety but also for cognitive support.
