Tulsi (Holy Basil)
Tulsi, or holy basil (Ocimum tenuiflorum), is a revered herb in India, considered sacred in Hindu tradition and one of the most important plants in Ayurveda. As a tisane its dried leaves brew into a warm, aromatic infusion with a clove-like, peppery, slightly sweet character that sits somewhere between culinary basil and a gentle spice. It is naturally caffeine-free and is traditionally classed in Ayurveda as an adaptogen, a herb popularly taken to help the body cope with stress.
Good tulsi is a fragrant green to purple-tinged cut leaf (sometimes with small stems and flower spikes) carrying a strong, warm, clove-and-pepper aroma. Faded, brown, or weakly scented material has lost the essential oils that define it and brews flat. The three main types, Rama (green and mellow), Krishna (purple and peppery), and Vana (wild and more complex), are sometimes sold separately or blended, and each has a slightly different intensity. A clear, golden infusion with a warm, spicy-sweet, clove-like character is the sign of quality. As with most aromatic herbs, a strong fresh smell from the bag is your best test.
Ocimum tenuiflorum (synonym Ocimum sanctum) is native to the Indian subcontinent and is grown throughout India, where it is planted in courtyards and temples and holds deep religious significance. The leaves, and sometimes flower spikes and tender stems, are harvested and dried with no oxidation step. It is one of the central herbs of Ayurveda, traditionally classed as a rasayana (rejuvenating tonic) and popularly taken as a daily infusion to support calm and resilience.
Use about 1 to 1.5 g per 100 ml (around 2 to 3 g per 250 ml cup), water at 95 to 100°C, steeped 5 to 7 minutes, covered to keep the aromatic oils in the cup. It is caffeine-free and not astringent, so a longer steep deepens the spice without bitterness. It re-steeps once for a milder cup. It blends naturally with ginger, mint, lemongrass, or a touch of honey.
€6-14 (about $7-15) per 100 g; plain tulsi is moderately priced, with branded organic and single-type (Krishna or Vana) grades at the higher end. Caffeine-free.

Peppermint
Peppermint is often blended with tulsi, the cooling mint playing against tulsi's warm, clove-like spice for a livelier, more refreshing cup.
Masala Chai
Masala chai shares tulsi's warm Indian spice register, but chai is a caffeinated black-tea base built on cassia, cardamom, and ginger, while tulsi is caffeine-free and singularly clove-peppery.
Jiaogulan
Jiaogulan is the other widely sold caffeine-free adaptogen-style infusion; both carry that traditional stress-support reputation, though jiaogulan is green and herbaceous where tulsi is warm and spicy.
Tulsi is so revered in India that it is often grown in a dedicated raised planter in the household courtyard and honored in daily ritual; its Sanskrit name is commonly translated as the incomparable one.
