Holy, or Sacred basil, is a stiff, leafy, perennial herb. The plant can reach up to 18 inches in height and develops small pink, fragrant blossoms when mature. With thicker stems, ranging in color from green to a dark purple, holy basil has a bushy appearance and can grow quite large. Holy basil’s narrow, oval leaves range from a light green to a deep purple color and are very aromatic. The taste does vary between types. However, it is often likened to cloves (anise) or licorice with a hint of mint and a bit of peppery spice. The pungent pink flowers are also edible.
Holy basil contains a rich supply of antioxidants. The essential oils in holy basil contain eugenol, which has anti-inflammatory properties and is being studied for its ability to inhibit cancer cell growth. Research has also been done on Holy Basil around its ability to help protect the stomach lining from the damage of aspirin. The ancient herb also contains compounds that aid in digestion and nutrient absorption in the digestive tract, making it a good addition to the diets of those with chronic digestive issues.
In the United States, it is most commonly used to make tea. However, in Thailand, it is a very popular culinary ingredient. Holy basil is an important ingredient in one of the more famous Thai street dishes, chicken with holy basil, or "gai pad grapow". Holy basil is used as an aromatic in many Thai stir-fry dishes, along with garlic, fish sauce, and chilies, to flavor meat, fish, or chicken. Holy basil is best used fresh, as its leaves do not maintain their aroma after a few days in the refrigerator.
Holy basil is available during the summer months.
