Holy Basil
Botanical Name: Ocimum sanctum
Origins: India, Tropical Asia
As an herbal tonic for the nervous system, holy basil is cherished for its abilities to lift the spirits, improve mood, and promote relaxation. It is one of the most beloved plants in Indian folk medicine and Ayurveda, an ancient system of healing rooted in more than three thousand years of Indian culture. In Ayurvedic medicine, holy basil is known as a rasayana, a natural substance that promotes health and longevity. In India, it is widely known by the names tulsi and tulasi, which translate to “the incomparable one,” reflecting the herb’s cultural importance.
Though holy basil is native to India, it grows throughout tropical Asia, where it is commonly used in cooking, folk medicine, and spiritual practices, while herbal medicine practitioners around the world typically consume it in teas and tinctures. As a relative of the culinary herb sweet basil, holy basil shares its aromatic quality but has a unique scent and flavor of its own, with notes of cloves, mint, and bubble gum. Its Latin name, Ocimum tenuiflorum, means “fragrant lipped slender flowers.” The use of “holy” in its English common name derives from another previously used Latin name for the herb, Ocimum sanctum.
In contemporary herbal medicine, holy basil is highly valued for its ability to help alleviate stress. It’s recognized both as a calming nervine that soothes the mind and as an adaptogenic herb with a normalizing effect on the body. Holy basil is thought to work in part by increasing circulation to the brain. This may help improve overall brain function, in turn reducing cloudy thinking and enhancing mental clarity.
Beyond its benefits to the nervous system, holy basil contains a bountiful bouquet of compounds with antibacterial, antiviral, antioxidant, and expectorant activity. These properties make the herb an ideal remedy whenever colds and coughs accompany stressful periods. It also contains a powerful combination of phytochemicals that are thought to give the herb its anti-inflammatory and stress-relieving properties.
