What is the botanical classification of lemon balm?
Scientifically, the herb name for lemon balm is Melissa officinalis. This plant is part of the Lamiaceae family, more commonly known as the mint family, which also includes other fragrant herbs like sage, thyme, and rosemary. Its classification is broken down into a hierarchical structure that includes its genus, Melissa, and its species, officinalis. The specific epithet officinalis is a New Latin term that means 'in use pharmaceutically,' highlighting its long history of medicinal application. The 'L.' often seen appended to its name refers to the botanist Carl Linnaeus, who first formally described the species.
A deeper look into the etymology: Why is it called Melissa?
The genus name Melissa comes from the Greek word for "honeybee," which is a direct nod to the plant's powerful appeal to bees. Ancient bee keepers and herbalists understood this connection well. First-century Roman naturalist Pliny the Elder wrote about rubbing the leaves on new beehives to attract bees and encourage them to stay. The sweet, lemony fragrance produced by the plant's leaves and flowers is what makes it so enticing to pollinators. This sweet scent has also contributed to other common monikers for the plant over the centuries, such as "sweet balm," "honey plant," and "bee balm".
