About this ingredient
Tulsi Leaf Extract (Ocimum sanctum, holy basil) is an extract from a plant used in Indian Ayurveda for a thousand years as an adaptogen and anti-inflammatory. It entered cosmetics with the wave of Ayurvedic trends in the 2010s. Composition. Contains eugenol, rosmarinic acid, ursolic acid, flavonoids (apigenin, luteolin). Eugenol and rosmarinic acid are the main bearers of in vitro activity – antioxidant and mildly anti-inflammatory. Where applied. Ayurvedic and Indian cosmetic brands (Forest Essentials, Kama Ayurveda), European clean-beauty lines with botanical positioning. In Spain it appears in niche Ayurvedic-leaning brands; rare in mass retail. Evidence base. The Pattanayak 2010 review describes anti-inflammatory and antibacterial effects of tulsi in vitro, in cell cultures, and in animal models. No clinical RCTs with topical use on human skin exist. Oral tulsi in patients with metabolic syndrome showed moderate effects on glycaemia (Jamshidi 2017), but that is a different context. Safety. The eugenol content is a known skin allergen requiring labelling. In patients sensitive to Lamiaceae essential oils (basil, thyme, oregano), cross-reactivity is possible. Pregnancy – use with caution. Eugenol has antiplatelet activity in vitro and oral tulsi in high doses in rat models reduced fertility. Topical use at cosmetic concentrations is minimally risky, but pregnant women with bleeding risk (post-IVF, on anticoagulants) should avoid it. Realistic expectations. A marketing-driven Ayurvedic ingredient with moderate in vitro activity. Not part of first-line routines for acne, rosacea, or age-related changes.
