Feuilles d'Ocimum gratissimum (Vana tulsi) C&S

In various healthcare traditions, Ocimum gratissimum is utilized for its diverse aromatic and bioactive properties. In Ayurveda, where it is known as Vriddhutulsi or Ram Tulsi, the plant is traditionally described as a Rasayana (rejuvenative) and is used to balance Kapha and Vata doshas. It is frequently employed in formulations intended to manage respiratory distress, such as coughs and bronchitis, or as a digestive stimulant to alleviate bloating and dyspepsia. Beyond the Indian subcontinent, in West African folk medicine, the leaves—often called "Scent Leaf"—are commonly prepared as aqueous decoctions or infusions to treat gastrointestinal ailments like diarrhea and stomach pain. Furthermore, across Brazilian and Southeast Asian traditional systems, the plant’s essential oils and leaf juices are applied topically for skin infections or used as a steam inhalant to clear nasal congestion, leveraging the high concentrations of phytochemicals like eugenol and thymol that are characteristic of the species.

The therapeutic potential of Ocimum gratissimum is primarily attributed to its high concentration of volatile essential oils and a diverse profile of secondary metabolites. The most dominant active ingredient is eugenol, a phenylpropene that often constitutes up to 70–85% of the leaf’s essential oil and is responsible for its characteristic clove-like scent and antimicrobial properties. Other significant volatile compounds include thymol, citral, linalool, and methyl chavicol, which vary in concentration depending on the plant’s geographic chemotype. Beyond its oils, the leaves are rich in phenolic compounds and flavonoids (such as vicenin and orientin) which provide potent antioxidant activity. The presence of saponins, alkaloids, and tannins further supports its traditional use in managing gastrointestinal and respiratory issues, while organic acids like rosmarinic acid contribute to the plant's documented anti-inflammatory effects.
