The name comes from Japanese: rei for cosmos, ki for spiritual energy, and the blend nods to Reiki's core idea of drawing tension and negativity out of the body, though what lands in the cup is really about the fruit. Expect a fresh, bright profile built on mango and apple, with rosehip, hibiscus, and orange rounding out the sweetness, plus a herbal edge from carrot peel and rose.
This is a loose-leaf herbal blend rather than a true tea: sultanas, apple pieces, and mango cubes sit alongside lemongrass, rose hip peel, hibiscus and cornflower blossoms, orange and carrot peel, stinging nettle and mulberry leaves, freeze-dried tangerine-orange pieces, mallow and marigold blossoms, rose petals and buds, and safflower. Tea & Coffee, who sell it, market it among their health and wellness teas, though the ingredient list reads more like a fruit basket than a medicine cabinet.
Steep it in freshly boiled water for five to ten minutes. The longer end draws out more of the fruit sweetness without turning bitter, since there's no true tea leaf underneath to overextract.
