单选题. Most of us trust our doctors even when they hand us a prescription for a drug we can't pronounce. But natural, holistic (全面的) products are fully in vogue nowadays, and the Internet has created a way for non-experts to become as—or more—informed as their general practitioner when it comes to obscure treatment methods. "People are now more willing to take their health and wellness into their own hands," says Danielle Hardee, a wellness advocate for doTERRA International. Oddly enough, until fairly recently, Hardee was not one of those people. Her first experience with essential oils came in treating her pet bulldog. After seeking suggestions for the sickly pet on Facebook, a fellow fosterer told Hardee about certain oils she could try applying to the animal's skin. Pairing her curiosity with healthy skepticism, Hardee dove deep into researching the safety of the oils. "I was very happy with everything I found," she says. "I started not just using them on the foster dog, but also our son, who needed the benefits of the respiratory support." While the dog's recovery was soon apparent, the benefits for her son were almost immediate. The oils in question are considered "essential" not due to any proven vitality, but because they contain the essence of the plants from which they are extracted. Peppermint, lavender and citruses are among the most common on the market today, but numerous essential oils have been in use for several centuries. After seeing how beneficial the concentrated liquids were to both the two-legged and four-legged members of her family, Hardee soon found herself teaching essential oil classes. "It became something I felt so strongly about, I had to share it," she says. The classes quickly grew in size and geographical span and Hardee soon became an advocate for doTERRA International, a natural nutrition and wellness company. As growing popularity pushes essential oils into the broader market, Hardee recommends curious customers proceed with caution concerning quality and purity. Hardee believes the effects of quality oils will be the evidence that helps them prevail. "I'm not a holistic health guru (专家)," she emphasizes. "I'm just seeing it with my own eyes."1. What is people's attitude to their health and wellness nowadays? ______
