Basil: An Underestimated Medicinal Plant

Basil: An Underestimated Medicinal Plant

Often reduced to its role in the kitchen, basil (Ocimum basilicum) is nevertheless one of the most historically charged plants of the Mediterranean flora. A true crossroads between table and apothecary, it has accompanied humanity since antiquity, both for its culinary uses and for its long-standing place in herbal traditions.

An Underestimated Digestive Leaf

Common basil stands out for its highly aromatic leaves, rich in volatile compounds. It is best known in the kitchen, but medicinal traditions also used it for the belly: slow digestion, gas, mild cramps, and discomfort after meals. Its strength is not to act forcefully, but to help release what contracts.

Digestive and Antispasmodic Properties

Basil has carminative, antispasmodic, and mildly anti-inflammatory properties, and is mainly used to support simple digestive troubles. Its aromatic molecules, such as linalool and eugenol, contribute to its relaxing effect on the smooth muscles of the digestive tract. Rosmarinic acid supports its antioxidant profile and explains part of its traditional use on minor irritations.

The genus Ocimum counts more than seventy species spread across the world. Some of these plants were emblems. Here is how four civilisations lived with them.

History & Mythology

Basilikón, the Herb of Kings

Its Greek name evokes what is royal. Theophrastus, Dioscorides, and Pliny are among the ancient authors who wrote about basil.

India

Tulsi, the Incomparable

Holy basil, distinct from culinary basil, remains a devotional plant closely associated with Vishnu.

The Leaves That Cool

In leaf baths and some Vodou rites, the plant belongs at once to care, symbol, and the spiritual world.

How to Prepare Basil

Infusion remains the simplest way to enjoy basil outside the kitchen. Let a small handful of fresh leaves, or one teaspoon of dried leaves, steep for 5 to 8 minutes in water around 85 °C. Cover the cup to preserve the aromas.

The leaf mainly contains volatile compounds — linalool, eugenol, methyl chavicol — as well as polyphenols such as rosmarinic acid, linked to its digestive, antioxidant, and soothing action.
