de Paula, L.C.L., Fonseca, F., Perazzo, F., Cruz, F.M., Cubero, D., Trufelli, D.C., . . . del Giglio, A. (2015). Uncaria tomentosa (cat's claw) improves quality of life in patients with advanced solid tumors. Journal of Alternative and Complementary Medicine, 21, 22–30.
To assess the efficacy of Uncaria tomentosa (cat’s claw) on quality of life, fatigue, anxiety, depression, and sleep quality in patients with terminal cancer when used in conjunction with monitoring for changes in biochemical and inflammatory parameters
A 100 mg dose of dry extract of Uncaria tomentosa (U tomentosa) was administered orally three times daily for eight weeks.
Overall quality of life (p = 0.00411) and social functioning (p = 0.0341) improved. Fatigue as assessed by the CFQ improved (p = 0.0496). No improvement in sleep quality anxiety was determined. There was no change in liver function, kidney function, blood counts, or inflammatory blood parameters.
Managing symptoms in patients with no additional treatment options is important. U tomentosa improved overall quality of life and social functioning and reduced fatigue in patients with cancer who had no additional treatment options. U tomentosa did not affect sleep quality, anxiety, or depression, but it did not alter the inflammatory parameters studied.
U tomentosa may be useful in reducing fatigue and improving overall quality of life in patients who have no other treatment options.
