Deep Relief Massage The Tei Fu essential oils formula was developed and perfected by a Chinese herbalist several decades ago. He created it using an ancient formula that had been passed down through his family for more than a thousand years. His secret formula was not for sale until he realized the benefits of his family secret and decided it was too good to keep from others. Thus, Nature’s Sunshine became the beneficiary of thousands of years of Chinese wisdom and herbal knowledge. Tei Fu Massage Lotion contains safflower oil, wintergreen oil, menthol, camphor and other essential oils in a creamy lotion form. It is especially designed for broad skin application. Use this skin-tingling formula for a deeply penetrating massage that focuses on relaxation and helps to relieve stiff, sore muscles. It leaves the skin smooth and supple.
