According to Indian Systems of Medicine, Spilanthes acmella (L.) Murr. (Family-Asteraceae), is considered effective in the treatment of sexual deficiencies especially due to aging. In the present study, characterization of ethanolic extracts of the Spilanthes acmella flower and its effect on general mating pattern, penile erection and serum hormone levels of normal male Wistar albino rats were investigated and compared with sildenafil citrate. In-vitro nitric oxide release was also investigated in human corpus cavernosum cell line. N-alkylamides are a promising group of naturally occurring bio-actives in Spilanthes spp. Therefore, N-alkylamide profiling of ethanol extract of Spilanthes acmella flowers was performed, using a gradient reversed phase high performance liquid chromatography/electrospray ionization ion trap mass spectrometry (HPLC/ESI-MS) method on an embedded polar column. MS 1 and MS 2 fragmentation data were used for identification purposes. The extracts (50, 100 and 150 mg/kg body weight/day) and sildenafil citrate (5mg/kg) were administered orally for 28 days. The behavioral parameters were observed at day 0, 15, 28 and after a lapse of 7 and 14 days of discontinuance of drug treatment.Five N-isobutylamides, one 2-methylbutylamide and one 2-phenylethylamide were tentatively identified. The orally administered extract had a dose dependent effect on mounting frequency, intromission frequency and ejaculation frequency. A dose dependent effect was also observed on the FSH, LH and testosterone serum levels. The aphrodisiac potential of an ethanolic Spilanthes acmella extract was demonstrated in-vitro and in-vivo. Study lends support to the traditional utilization of S. acmella as a sexual stimulating agent.

Alopecia is a dermatological disorder with psychosocial implications on patients with hair loss. Eclipta alba Hassk. is a well-known Ayurvedic herb with purported claims of hair growth promotion. In the reported work attempts were undertaken to evaluate petroleum ether and ethanol extract of E. alba Hassk. for their effect on promoting hair growth in albino rats. The extracts were incorporated into oleaginous cream (water in oil cream base) and applied topically on shaved denuded skin of albino rats. The time (in days) required for hair growth initiation as well as completion of hair growth cycle was recorded. Minoxidil 2% solution was applied topically and served as positive control for comparison. Hair growth initiation time was significantly reduced to half on treatment with the extracts, as compared to control animals. The time required for complete hair growth was also significantly reduced. Quantitative analysis of hair growth after treatment with petroleum ether extract (5%) exhibited greater number of hair follicles in anagenic phase (69 +/- 4) which were higher as compared to control (47 +/- 13). The result of treatment with 2 and 5% petroleum ether extracts were better than the positive control minoxidil 2% treatment.

Clinical evaluation proceedings from patient-reported outcomes (PRO) are being concerned increasingly. Based on the concept of PRO, the report discusses the findings in the research recently made at home and abroad. PRO from apoplexy patients with spastic paralysis was taken as an example in the exploration of how to evaluate the curative effects in clinical practice on the basis of PRO.

The roots of Asparagus racemosus, Chlorophytum borivilianum, and rhizomes of Curculigo orchioides are popular for their aphrodisiac and immunostimulatory properties. The herbs have been traditionally used as Vajikaran Rasayana herbs because of their putative positive influence on sexual performance in humans. Lyophilized aqueous extracts obtained from the roots of A. racemosus, C. borivilianum, and rhizomes of C. orchioides were studied for sexual behavior effects in male albino rats and compared with untreated control group animals (total N = 60). The rats were evaluated for effect of treatments on anabolic effect. Seven measures of sexual behavior were evaluated. Administration of 200 mg/kg body weight of the aqueous extracts had pronounced anabolic effect in treated animals as evidenced by weight gains in the body and reproductive organs. There was a significant variation in the sexual behavior of animals as reflected by reduction of mount latency, ejaculation latency, post ejaculatory latency, intromission latency, and an increase of mount frequency. Penile erection (indicated by Penile Erection Index) was also considerably enhanced. Reduced hesitation time (an indicator of attraction towards female in treated rats) also indicated an improvement in sexual behavior of extract treated animals. The observed effects appear to be attributable to the testosterone-like effects of the extracts. Nitric oxide based intervention may also be involved as observable from the improved penile erection. The present results, therefore, support the folklore claim for the usefulness of these herbs and provide a scientific basis for their purported traditional usage.
