The amethyst, a semi-precious stone worn by ancient Greeks to prevent intoxication is the focal point of the signature massage at the swank Okura Spa in the Okura Prestige Hotel. The stone is used to balance physical, mental, and emotional energy. At the Okura, patients get a professional consultation before each treatment session, and their well trained therapists use only exclusive organic teas, oils and balms (the signature Okura Spa oil contains traces of white tea, sandalwood, jasmine and a predominance of lavender) . What sets Okura apart though are their ta-ke Japanese massage treatments, which feature the use of heated bamboo rods used to knead and roll out knots, relax tense muscles and reduce stress and fatigue, as well as increase blood circulation.
