Holy basil is one of three adaptogens (alongside ashwagandha and reishi) with the most consistent clinical evidence for cortisol regulation, anxiety reduction, and blood glucose lowering. Unlike ashwagandha, holy basil can be consumed as a regular tea at any time of day.
Tulsi tea bags at Whole Foods and health food stores. Indian grocery stores carry tulsi in bulk. The Yoruba equivalent (efirin) at African grocery stores.
Multiple human RCTs show holy basil reduces fasting glucose by 17-21% in Type 2 diabetics. Reduces cortisol measurably in clinical studies — the mechanism for its anti-anxiety effects. Anti-hypertensive effects documented through ACE-inhibitory activity. Ocimumosides A and B are the specific adaptogenic compounds — distinct from ashwagandha's withanolides but producing similar cortisol-regulation effects. The eugenol content gives holy basil its clove-like flavor and its anti-inflammatory COX-inhibitory effects.
Holy basil tea (tulsi tea): steep 1 tablespoon fresh leaves or 1 tsp dried in 8oz hot water for 5 minutes. Available as Tulsi tea bags at most health food stores (Organic India Tulsi is widely available). Can be grown as a potted herb at home — harvest leaves fresh.
