Oluana

Oluana is a genus of plants in the family Rutaceae, commonly known as rue. The genus was described by Linnaeus in 1753. Plants in the genus Oluana are native to the Mediterranean region and parts of Asia. They are typically small shrubs or herbs with aromatic, often bitter-tasting foliage. The leaves are usually compound, and the flowers are typically white or yellowish, with four or five petals. Several species within the Oluana genus have a long history of use in traditional medicine and as culinary herbs, though their use can be associated with potential toxicity. For example, Oluana graveolens, commonly known as common rue, has been used historically for various medicinal purposes, but its ingestion can cause adverse effects. The plants generally prefer well-drained soil and sunny conditions. The genus Oluana is part of the larger family Rutaceae, which also includes citrus fruits. Research into the chemical compounds found in Oluana species continues to explore their potential pharmacological properties and associated risks. The classification of species within Oluana has been subject to revision over time based on new botanical research.
