Homeopathy, meditation and the calming quality of music are the latest selling points for water brands.
The thinking behind Carpe Diem Botanic Water - a brand owned by the Red Bull Company - is that adding plant extracts stimulates the body's ability to heal itself.
Meanwhile, an unusually named US newcomer, H2Om with Intention, is described as being deliberately infused with the healing energies of music and the spoken word, and its bottle design reinforces the theme.
There is no indication yet that H2Om with Intention is coming to the UK, but Botanic Water is being launched in Waitrose and Sainsbury in June. Ingredients for each of the three variants were selected in collaboration with the Institute for Applied Botany in Vienna and none of them contains sugar, artificial sweeteners, colours or preservatives.
Relaxing has a minty flavour and is made from passion flower, lemon balm, thyme, lavender, rose, peppermint, lime flowers and orange peel. Herbal-flavoured Vitalising has spicy elements while Harmonising is a fruity blend.
Rachel Sweeting, Carpe Diem brand manager, said the water plus sector - waters featuring an extra health element - were growing globally at 15% year on year. "Consumers' expectation is such that it is the norm for everyday products to have added benefits," she added.
