Holy Basil (Tulsi) Extract
Also known as: Ocimum sanctum, Ocimum tenuiflorum, tulsi, sacred basil
A leaf extract of tulsi, an aromatic basil revered in Ayurvedic tradition and used in modern formulas as a gentle adaptogen for stress and metabolic balance. A systematic review of human trials reported favorable effects on stress, mood, and metabolic markers with good tolerability, while noting that dosing and preparations varied widely across studies. It is often combined with ashwagandha or rhodiola, and its pleasant clove-like aroma suits teas and powders.
