*Lippia alba*, commonly known as shrubby lemon verbena (*erva-cidreira-de-arbusto*), is an aromatic plant native to the tropical and subtropical regions of the Americas and belongs to the Verbenaceae family. It is a highly branched perennial shrub that can grow vigorously, reaching a height of approximately 1 to 2 meters. Its leaves are green and aromatic, varying in shape depending on the specific variety. When crushed, they release a distinctive scent attributed to the presence of essential oils.

The plant goes by various common names, such as *erva-cidreira*, Brazilian lemon verbena, shrubby lemon verbena, and false lemon balm. Its aroma may exhibit notes resembling lemon or lemon balm, depending on the plants chemotype. This chemical variation is a significant aspect of the species, as different *Lippia alba* populations can display distinct essential oil compositions.

In folk tradition, the leaves of this shrub are primarily used to prepare teas and in other traditional forms of consumption. The plant is traditionally associated with relaxation, well-being, and digestive comfort, featuring prominently in traditional knowledge regarding aromatic and medicinal plants. However, traditional use should not be confused with proven efficacy in treating specific diseases.

From a scientific perspective, *Lippia alba* attracts interest due to its composition of essential oils and phenolic compounds, which are being investigated in fields such as pharmacognosy, phytochemistry, and botany. Components found in various chemotypes include substances such as citral, carvone, limonene, and linalool; the proportions of these substances can vary based on the plants genetics, the environment, and cultivation conditions.

Ecologically, the shrubby lemon verbena is also significant as an aromatic plant that attracts various organisms; it is suitable for inclusion in gardens, medicinal herb patches, educational spaces, and biodiversity-oriented cultivation systems. Its relatively simple cultivation and distinctive aroma make it an interesting species for environmental education projects, the valuing of traditional knowledge, and the conservation of plant diversity.
