Synopsis

Source of validity: Traditional
Rating (out of 5): 3

Holy Basil (Ocimum sanctum, also known as Tulsi) has a long history of use in Ayurvedic and traditional medicine, primarily for its purported adaptogenic properties — that is, its ability to help the body adapt to stress. Specifically, it is believed to support the adrenal cortex, which is responsible for producing stress-related hormones such as cortisol. Traditional texts describe Holy Basil as a "rasayana," or rejuvenating herb, used to promote vitality, reduce fatigue, and support overall resilience to physical and emotional stress.

Several animal studies and limited human trials suggest Holy Basil may help modulate the body's stress response and support adrenal health by influencing cortisol levels and reducing the physiological impact of stress. However, robust, large-scale clinical evidence directly linking Holy Basil to improved adrenal cortex function in humans is lacking. The majority of the evidence remains preclinical or based on traditional use. Consequently, its use for adrenal support is justified primarily by tradition, supported by some preliminary scientific data but lacking definitive clinical validation.

In summary, Holy Basil is traditionally used to support the body's stress response and, by extension, the adrenal cortex, but current scientific evidence is moderate and not conclusive.
