Abstract
The use of medicinal plants has been increasing in recent years, especially in traditional and complementary medicine worldwide. Many of these medicinal plants are consumed without sufficient scientific backing, which can have consequences for people’s health and impose significant healthcare costs on the system. Among these, Lavandula angustifolia is one of the most common herbal medicines due to its widespread use in traditional medicine. The use of Lavandula angustifolia has been well demonstrated in various studies for some conditions such as anxiety disorders and sleep disorders. However, evidence for its effectiveness in treating other diseases is contradictory or limited. This study examines the importance of the active ingredient of Lavandula angustifolia and the processing and post-harvest methods in the food and pharmaceutical industries based on existing research.
