Among all major genera and species in the mint family, different types of organic compounds or metabolites such as phenolic compounds, flavonoids, anthocyanins, ascorbates, and carotenoids with antioxidant, antimicrobial, and anti-inflammatory effects are produced by means of metabolic processes. Research studies in this field have established that planting distance can have a significant effect on essential oil yield as well as the quantity and quality of secondary metabolites in medicinal plants. The main purpose of spacing between plants is also to provide a suitable mix of environmental factors (i.e. water, climate, light, and soil) to achieve optimum quality performance.
