I slowly rub my hands together and bring my palms up to my face. I close my eyes as instructed and breathe in gently. A delicate, sweet, earthy scent fills my nostrils as I’m invited to centre myself in time and space. I open my eyes and take a sip of the tea created just for this moment: a deeply aromatic blend of mugwort, lemon verbena and angelica root. I begin to feel remarkably relaxed and forget about the hordes of tourists in the streets outside.
