The bar chart illustrates the proportion of U.S. adults using various Complementary or Alternative Medicine (CAM) therapies in 2007, while the table compares the percentage increases in participation for selected therapies between 2002 and 2007.
Overall, natural products were by far the most commonly used therapy in 2007, whereas practices such as homeopathic treatment and guided imagery were the least popular. In parallel, all four therapies listed in the table experienced noticeable growth over the five-year period, with deep breathing showing the most substantial increase.
In detail, approximately one-fifth of American adults used natural products in 2007, placing this category well ahead of the others. Deep breathing ranked second, at just under 15%, followed by meditation at around 10%. Chiropractic care, massage, and yoga occupied the mid-range, each attracting roughly 6-8% of users. By contrast, diet-based therapies, progressive relaxation, guided imagery, and homeopathy were comparatively marginal, each below 5%.
Turning to the table, deep breathing rose markedly from 10.6% in 2002 to 14.8% in 2007, representing the largest gain. Massage also saw a significant increase, climbing from 5% to 8.6%. Meditation grew more modestly, from 8.6% to 10.5%, while yoga experienced the smallest rise, from 5.1% to 7.1%.
In summary, CAM therapies gained popularity overall, with breathing techniques and massage showing particularly strong upward trends, while natural products remained dominant in terms of overall usage.
