The foliage is characterized by a light green color and a distinctively aromatic, lemon-scented quality due to essential oils. Its stems are herbaceous and often develop a woody base as the plant matures over several seasons. During the flowering period, the plant produces small, two-lipped flowers that are typically white or pale lilac. These blossoms emerge from axillary clusters and are primarily arranged in verticillasters along the upper portions of the stem.
What is the geographical distribution of this plant?
This plant is native to a wide geographic range spanning Southern Europe, North Africa, and Western Asia. It thrives in various climates ranging from the Mediterranean basin to the temperate regions of the Middle East. Due to its popularity in herbal medicine and culinary applications, it has been widely naturalized in many other parts of the world. Human cultivation has successfully introduced the species to North America and parts of South America. Today, it can be found growing in gardens and disturbed soils across most temperate latitudes globally.
How is this plant cultivated?
This plant, commonly known as lemon balm, thrives in well-drained soil with moderate moisture and requires full sun to partial shade for optimal growth.
It is a hardy perennial that spreads easily through underground runners, so it is often best to plant it in containers to prevent it from overtaking a garden. Regular watering is necessary during dry spells, but the roots should never sit in stagnant water to avoid rot. Harvesting the fragrant leaves is most effective just before the plant flowers to ensure the highest concentration of essential oils.
Once established, this resilient herb can withstand various climates and requires minimal maintenance throughout the growing season.
What parts of this plant are used medicinally?
This plant Melissa officinalis is primarily used medicinally through its folium melissae, which refers to the aromatic leaves that contain the essential oils used to treat anxiety and digestive issues. While the leaves are the most common therapeutic component, the flowers are also harvested to create calming teas and tinctures. The stem is rarely utilized in traditional remedies, but it can be included in certain herbal preparations. Although most medicinal value resides in the aerial portions, some historical practices involve the use of the root for specific topical applications. Together, these various parts provide a diverse range of phytochemicals for holistic wellness.

What are the pharmacological activities of Melissa officinalis?
This plant has anxiolytic, acetylcholinesterase inhibition, sedative, antispasmodic, and antioxidant pharmacological activities. The presence of specific polyphenols allows the extract to combat oxidative stress through its potent antioxidant properties. Its ability to inhibit acetylcholinesterase makes it a significant subject for research regarding cognitive enhancement and Alzheimer's disease. Additionally, the plant exerts a calming effect on the central nervous system to provide sedative and anxiolytic benefits. Finally, its antispasmodic actions help relax smooth muscles to alleviate various gastrointestinal or menstrual discomforts.
According to a study published by "Neuropsychopharmacologia Hungarica : a Magyar Pszichofarmakologiai Egyesulet lapja = official journal of the Hungarian Association of Psychopharmacology", herbal medicinal products based on Melissa officinalis L. demonstrate an anxiolytic effect. The research tested two dosages of the drug, specifically 5 ml and 2.5 ml per 1 kg of animal weight. These preparations produced notable effects by alleviating stress and reducing phobic reactions while enhancing locomotion, exploratory, and searching activities. These pharmacological activities were observed across 3 behavioural test systems, including the black and white chamber, elevated cruciform maze, and open field. Data regarding the comparability of quantitative changes at different dosages suggests that a lower dosage of 2.5 ml/kg can be used in subsequent studies.
The primary pharmacological activities of this plant are shown in the list below.
- 1. anxiolytic
- 2. acetylcholinesterase inhibition
- 3. sedative
- 4. memory improving
- 5. anti-inflammatory
What medicinal compounds this plant contains?
This plant contains a diverse range of bioactive phytochemicals including rosmarinic acid, citral, melitric acid A, flavonoids, and terpenes. Rosmarinic acid provides significant antioxidant and anti-inflammatory properties to the botanical profile. The presence of citral contributes to the characteristic lemon-like aroma and antimicrobial activity. Various flavonoids act as potent scavengers of free radicals within the organism. Additionally, terpenes serve as essential aromatic components that offer sedative and antispasmodic effects.
According to a study published by "Nutrients", rosarinic acid is found in medicinal and spice plants such as Melissa officinalis. The study investigated the effects of rosarinic acid when administered orally at a dose of 10 mg/kg or 50 mg/kg daily for 28 days. In ovariectomized rats, administration of rosarinic acid at both doses induced decreases in fructosamine concentration and the HOMA-IR index. Additionally, the 50 mg/kg dose of rosarinic acid induced a decrease in total cholesterol and triglyceride concentrations. The research suggests that rosarinic acid may be useful in the prevention of metabolic disorders associated with estrogen deficiency.
The primary medicinal compounds of this plant are shown in the list below.
- Rosmarinic acid
- Citral

These diverse forms allow for versatile administration depending on the desired therapeutic effect.
According to a study published by "BMC plant biology", Melissa officinalis is a vital industrial and medicinal plant utilized in pharmaceutical, food, and cosmetic industries due to bioactive metabolites like terpenoids and phenolic compounds. Under drought stress at 75% field capacity, chlorophyll a was 0.74 mg/gFW and total chlorophyll was 1.00 mg/gFW. Drought stress also elevated electrolyte leakage to 32.45% and proline to 1.26 µmol/gFW. The combined Si-NP and SAP treatment yielded the highest flavonoid concentrations of 6.76 mg QE/g DW and antioxidant activity of 59.37%. Essential oil content peaked at 0.29% under drought stress, with geranial reaching 51.53% in control and SAP treatments, while neral maximized at 34.95% with SAP alone. Additionally, Si-NPs elevated linalool acetate to 5.71% and drought stress increased isopulegol to 11.16%.

Dominant compounds in the essential oil included neral (33.5-0%), citral (28.53-0%), geranial (28.25-0%), caryophyllene (20.71-0%), caryophyllene-oxide (19.73-7.36%), and geranyl acetate (5.99-11.84%). Regarding antimicrobial activity against Pseudomonas aeruginosa, the lowest MIC value was <62.5 μg/mL for treatments of nano iron 100, nano silver 20, and nano silver 60 mg/L. This activity was one times weaker than rifampin and three times more potent than the control treatment.
The main side effects this plant can have are shown in the list below.
