Herb Highlights – Lavender
Introduction
The first documented use of Lavender was in 77 B.C.E. by the Romans. Their use of lavender was relegated to soothing insect bites as well as repelling them.1 In addition to being grown for ornamental purposes, lavender flowers are commonly used in herbal medicines and sachets. In fact, the leaves are an ingredient in the herb seasoning blend herbs de Provence.2 Although it’s native to the Mediterranean, lavender is very resilient and varieties are grown throughout the US and the world.3 Here in Oregon, there are several dozen lavender farms in the Willamette Valley alone!
Lots of Lavender
There are over 40 species of Lavender,4 even more subspecies, and countless hybrids and cultivars.3 However, the most commonly used for commercial purposes is Lavandula angustifolia or English Lavender. In fact, it was previously named Lavandula officinalis2 to claim its authority. This species is used in food, to make essential oils,4 and dietary supplements, including herbal teas.2 The other popular and frequently seen species is Lavandula stoechas or Spanish Lavender, which is less frost-resistant and cannot be grown as widely as L. angustifolia. However, it is similarly used as an air freshener and herbal medicine.5
Lengthy History
Similar to chamomile, lavender’s use over time is due to its effectiveness. In the first century, Dioscorides praised it for its medical uses.6 However, unlike Chamomile, Lavender does not have any known interactions with drugs.7 Therefore, it is considered to be safe when taken in moderation though caution should be taken with chronic use of lavender essential oil as it can be toxic to the kidney and liver.8
