Tei Fu® Essential Oils [Nervous] was developed and perfected by a Chinese herbalist several decades ago. He created it using an ancient formula that was passed down in his family for more than 1,000 years. His secret formula was not for sale—a trait typical of older-generation Chinese. This descendant 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 Oils contain safflower oil, wintergreen oil, menthol, camphor and other essential oils. Tei Fu oils can be used for a wide variety of applications, especially where the refreshing, invigorating properties of essential oils are desired. Avoid contact with eyes and nose.
