Safety Overview
1.Lavanga — Botanical Snapshot
Lavanga, commonly known as Clove and scientifically classified as Syzygium aromaticum var., is a majestic perennial tree belonging to the extensive Myrtaceae family. Typically reaching heights of 10 to 20 meters, this evergreen species is characterized by its robust trunk and dense canopy.
Its leaves are distinctively opposite, glossy, and elliptical to ovate in shape, measuring between 7-12 cm in length and 3-6 cm in width, often exhibiting slightly wavy margins. The bark, initially smooth and light brown, gradually develops a darker, fissured texture as the tree matures.
The most prized part of Lavanga is its aromatic flower buds, which are meticulously harvested before they fully bloom. These buds, resembling small nails, typically measure 1.2-2.5 cm and undergo a transformative reddish-brown coloration upon drying.
They are a concentrated reservoir of potent essential oils, with eugenol being the predominant constituent responsible for Clove's characteristic pungent aroma and profound medicinal efficacy. After flowering, the tree produces small, berry-like fruits, usually 1-2 cm in diameter, which transition from green to a vibrant crimson hue as they ripen.
Syzygium aromaticum thrives in humid, tropical climates, preferring well-drained, loamy soils. Its native origins trace back to the Maluku islands of East Indonesia, but its cultivation has expanded globally to key producing regions such as Madagascar, Sri Lanka, India, Malaysia, and Tanzania, particularly Zanzibar island.
In Brazil, cultivation is significant in the northeast region, notably in the state of Bahia. Genetically, Clove shares close kinship with other species within the Syzygium genus, which encompasses various fruit-bearing and ornamental plants, underscoring its botanical significance within the Myrtaceae family.
