Tulsi /Holy Basil: now widely available online or at your favorite tea shop, look for loose leaf organic c/s (cut and sifted) which refers to the dried herb (which may include leaf, root, bark), as distinct from ground tulsi powder or sachets.
Tea vs. Tisane: although I refer to this drink as a tea, strictly speaking it is a tisane (technically, tea refers to a specific species of plant known as: Camellia Sinensis and true teas are derived, in one form or another, from that plant. Tisane (also known as herbal tea) is an infusion made from other plant leaves, roots, bark, seeds, berries, spices, etc.
Coffee Lovers: save the tea infusion after use and add it to your coffee basket - your next batch of brewed coffee will have a beautiful Indian-spiced flavor.
