The extracts of Scutellaria baicalensis and Acacia catechu have been shown in previous studies to alleviate joint discomfort, reduce stiffness, and improve mobility by reducing the production of proinflammatory molecules over long periods of supplementation. The acute effects of intake of these extracts have not yet been investigated. Thus, we carried out a 1 week clinical trial to examine the extent to which UP446—a natural proprietary blend of S. baicalensis and A. catechu (UP446)—decreases knee joint pain, mobility, and biomarkers of inflammation in comparison to naproxen. Seventy-nine men and women (40–90 years old) diagnosed as having mild to moderate osteoarthritis (OA) consumed either 500 mg/day of the UP446 supplement or 440mg/day of naproxen for 1 week in a double-blind randomized control trial. Pain, knee range of motion (ROM), and overall physical activity were evaluated at the start and at the end of treatment. Fasting blood was collected to determine serum interleukins 1b and 6, tumor necrosis factor-a, C-reactive protein, and hyaluronic acid. The UP446 group experienced a significant decrease in perceived pain (P = .009) time dependently. Stiffness was significantly reduced by both treatments (P= .002 UP446, P = .008 naproxen). Significant increases in mean ROM over time (P = .04) were found in the UP446 group. These findings suggest that UP446 is effective in reducing the physical symptoms associated with knee OA.

Functional foods and/or their bioactive compounds playing a role in improving skeletal health have received considerable attention. The objective of the present study was to determine the extent to which certain functional foods as (1) whole, e.g., dried plum (DP), figs, dates, raisin, and blueberry, (2) fractionated, e.g., DP puree, DP juice, and DP pulp/skin, or (3) isolated, e.g., DP polyphenols, fructooligosaccharides (FOS), and β-hydroxy-β-methylbutyrate, forms reverse bone loss in an ovariectomized (Ovx) rat model of osteoporosis. Additionally, some of these components were tested in reversal of bone loss in combination. For this purpose, 180 3-month-old female Sprague-Dawley rats were divided into 15 groups (n=12) and either Ovx (14 groups) or sham-operated (Sham, one group). Rats were maintained on a semipurified standard diet for 45 days after surgery to establish bone loss. Thereafter, rats were placed on one of the following dietary treatments for 60 days: casein-based diet (Sham and Ovx). The remaining 13 Ovx groups were placed on various treatment diets. Results showed that diets supplemented with 5% FOS+7.5% DP was most effective in reversing both right femur and fourth lumbar bone mineral density and fourth lumbar calcium loss while significantly decreasing trabecular separation. There were no significant effects of treatment on serum or urine measures of bone turnover. Although other treatments were good at altering some bone parameters, none had the success in altering several bone health indicators as the diets supplemented with 5% FOS+7.5% DP. The findings of this study suggest the combination of 5% FOS+7.5% DP is capable of reversing Ovx-induced bone loss.
