BackgroundTribulus terrestris as a herbal remedy has shown beneficial aphrodisiac effects in a number of animal and human experiments. This study was designed as a randomized double-blind placebo-controlled trial to assess the safety and efficacy of Tribulus terrestris in women with hypoactive sexual desire disorder during their fertile years. Sixty seven women with hypoactive sexual desire disorder were randomly assigned to Tribulus terrestris extract (7.5 mg/day) or placebo for 4 weeks. Desire, arousal, lubrication, orgasm, satisfaction, and pain were measured at baseline and after 4 weeks after the end of the treatment by using the Female Sexual Function Index (FSFI). Two groups were compared by repeated measurement ANOVA test.ResultsThirty women in placebo group and thirty women in drug group completed the study. At the end of the fourth week, patients in the Tribulus terrestris group had experienced significant improvement in their total FSFI (p < 0.001), desire (p < 0.001), arousal (p = 0.037), lubrication (p < 0.001), satisfaction (p < 0.001) and pain (p = 0.041) domains of FSFI. Frequency of side effects was similar between the two groups.ConclusionsTribulus terrestris may safely and effectively improve desire in women with hypoactive sexual desire disorder. Further investigation of Tribulus terrestris in women is warranted.

Dry mouth is a common complication of radiotherapy for head and neck cancers. This study compared the efficacy of an herbal compound containing Malva sylvestris and Alcea digitata (Boiss) with artificial saliva (Hypozalix) for improving the symptoms of dry mouth in head and neck cancer patients. The study examined a total of 62 subjects assigned to 2 groups. The herbal compound and Hypozalix were administered for 4 weeks. Efficacy was assessed using the visual analog scale and by grading the degree of dry mouth. Both groups showed a significant difference between visual analog scale before and following intervention. There was also a significant difference in visual analog scale between groups at 4 weeks after onset of intervention. The herbal group showed a significant difference between the grade of dry mouth before and after intervention, but no change was observed for grade of dry mouth in the Hypozalix group. This study supports the efficacy of the herbal compound for controlling symptoms of dry mouth in head and neck cancer patients.
