Mentolissas

Mentolissas is a genus of herbaceous flowering plants in the mint family, Lamiaceae. The genus is described in several botanical references as containing several species that produce a characteristic menthol-like aroma. The taxonomic status of Mentolissas is unsettled: some classifications place its species within Mentha, while others recognize Mentolissas as a distinct genus established in the late 20th century.

Plants are perennial, with square stems and opposite leaves. Leaves are 2–7 cm long, ovate to lanceolate with serrated margins, and emit a strong minty or camphor-like scent when crushed. The flowers are small, bilabiate, typically arranged in dense spikes or verticillasters, and range in color from white to pale purple.

Native to the Mediterranean basin and adjacent temperate regions of Eurasia; it is widely cultivated and naturalized in temperate gardens and coastal climates.

Chemistry and uses: Essential oils from many species contain menthol, menthone, and related monoterpenes. The oils are used in flavorings, fragrances, and some traditional medicines. While some folk remedies attribute digestive or respiratory benefits to Mentolissas, modern clinical evidence remains limited.

Cultivation and ecology: Prefers well-drained soil, full sun to light shade, and regular moisture. Propagation is by division or stem cuttings in spring or early summer. Regular pruning keeps the plant dense; some species can spread vigorously in favorable climates.
