Ancient cultures have used holy basil essential oil for diabetes, anxiety, stress relief, psychiatric imbalances, sleep disorders, migraine headaches and anxiety. In spiritual healing, Sacred Basil has been used to open the highest centers of the brain. In modern times, Holy Basil is also used to reduce viral hepatitis,  stress and herpes. It reduces inflammation and swelling for diabetics and is an excellent choice to build strong adrenals. I do not use Basil with pregnant or lactating women.In combinations, Lime and Lemongrass boost Basil's potency.
