Botanical Profile
Myrtus communis is the common myrtle, an evergreen aromatic shrub or small tree of the Myrtaceae. Leaves, fruits, flowers and essential oil shape the botanical, culinary and traditional significance of the species in the Mediterranean region.
Myrtus communis L. is an evergreen, densely branched shrub or small tree with opposite, leathery, glossy and aromatically fragrant leaves. The species is native to the Mediterranean region and adjacent areas and grows preferentially in maquis, scrub, open woodland, coastal areas and dry sunny sites. The white to slightly pink flowers bear numerous conspicuous stamens and develop into dark blue to black-violet berries. The plant is strongly aromatic; leaves and young twigs contain essential oil, while the fruits are characterised by tannins, pigments, sugars and aromatic constituents. Myrtle must be botanically distinguished clearly from Myrica gale, bog myrtle; the two plants belong to different families and should not be confused despite partially similar common names.
Phytochemistry
Myrtle is characterised particularly by essential oil, phenolic compounds and tannins. The essential oil frequently contains 1,8-cineole, alpha-pinene, myrtenyl acetate, linalool, limonene and other monoterpenes. Exact composition varies with origin, plant part, harvest time and distillation conditions. Leaves and young twigs provide aromatic, slightly balsamic to camphoraceous notes, while the berries additionally contain pigment- and tannin-rich fractions. Flavonoids, tannins and related polyphenols are described in phenolic fractions. For extracts and essential oils, clear differentiation among leaf, twig, fruit, flower and distilled oil is therefore necessary.
Traditional Uses
Myrtle has been known in the Mediterranean since antiquity as a fragrance, spice, ornamental and traditional plant. Leaves and fruits were used in regional cuisines, liqueurs, fumigations, cosmetics and simple herbal preparations. In Greco-Roman, Jewish and Mediterranean traditions, myrtle also possesses symbolic significance, for example in connection with purity, festivity, marriage and protection. Depending on the region, traditional uses refer to leaves, fruits, flowering twigs or essential oil. Historical descriptions must be carefully distinguished from modern efficacy claims.
Current Research
Current research on Myrtus communis addresses variability of essential oils, chemotypes, phenolic constituents, antimicrobial test systems, antioxidant models and food-technological applications. Work on essential oil investigates particularly fluctuations in monoterpene composition. Polyphenol studies consider leaves and berries as distinct raw materials. Many experimental studies use in-vitro models or isolated fractions; without further assessment, product-related or health-related claims cannot be derived from them. Plant part, origin, extraction process and analytical specification are decisive for robust classification.
