Tulsi — Holy Basil
Tulsi, Ayurveda's most revered daily herb, shows meaningful effects on stress, mood, and blood-sugar in a growing set of human trials.
How it works
Its actives (eugenol, ocimumosides, ursolic acid) act as mild adaptogens — moderating cortisol response — with trials reporting reduced anxiety and improved fasting glucose. Steadier blood sugar is quietly also a skin play: less glycation, less collagen cross-linking.
The practice
The gentlest format is tea: 1–2 cups of tulsi tea daily, especially as an afternoon caffeine replacement. Cycles of 6–8 weeks, then pause and notice.
The tradition
Ayurvedic Rasayana; the 'incomparable one' of household herbs
Cautions
- ⚠ Discuss with a clinician if on diabetes medication (additive effects).
- ⚠ Avoid concentrated extracts in pregnancy.
