Randomized Controlled Trial Clinical TrialThe effectiveness of tipi in the treatment of hip and knee osteoarthritis--a preliminary report.
Osteoarthritis (OA) is a common painful inflammatory condition occurring mainly in the later half of life. Hip and knee are the joints mostly affected. Petiveria alliacea (tipi) popularly known as an anti-rheumatic medicine, has been used by OA patients to relief pain. ⋯ The comparison between the improvements reported while on tipi and placebo tea, however, did not disclose any statistically significant difference. At the conclusion of the study 7 patients preferred tipi tea and 6 preferred placebo tea (NS). Two patients reported insomnia, one during placebo treatment and the other during tipi treatment.
