Raw Material Introduction | Lavender Spike

▎Essential Oil Introduction

Lavender mainly grows on limestone-rich slopes and dry and barren areas below 500 meters above sea level. Not cold-tolerant, but has heat-tolerant properties. It is native to the Western Mediterranean, southern France and the Iberian Peninsula, and is currently mainly produced in Spain.

The flower shape of lavender spike is slightly taller than true lavender, and the leaves are wider. It is also called broad-leaf lavender. Compared with the gentle and sweet true lavender, the aroma of lavender spike has a strong camphor aroma and strong refreshing feeling, but the smell will change depending on the place of origin and chemical composition. When we need to relieve stress, lavender spike is a good choice.
