Holy Basil
Holy basil aids in the fight against illnesses and increases immunity. Holy basil, not to be confused with normal basil or Thai basil, is regarded as a sacred herb in India. According to research, holy basil can suppress the growth of a variety of bacteria, yeasts, and molds.
One tiny study also discovered that it can improve immune system function by boosting specific immune cells in the blood. Holy basil has also been associated with lower blood sugar levels before and after meals, as well as anxiety and anxiety-related depression treatment. These studies, however, were rather small, and further study is required before any suggestions can be made.
