The use of plant or plant-based products to stimulate sexual desire and to enhance performance and enjoyment is almost as old as the human race itself. The present paper reviews the active, natural principles, and crude extracts of plants, which have been useful in sexual disorders, have potential for improving sexual behaviour and performance, and are helpful in spermatogenesis and reproduction. Review of refereed journals and scientific literature available in electronic databases and traditional literature available in India was extensively performed. The work reviews correlation of the evidence with traditional claims, elucidation, and evaluation of a plausible concept governing the usage of plants as aphrodisiac in total. Phytoconstituents with known structures have been classified in appropriate chemical groups and the active crude extracts have been tabulated. Data on their pharmacological activity, mechanism of action, and toxicity are reported. The present review provides an overview of the herbs and their active molecule with claims for improvement of sexual behaviour. A number of herbal drugs have been validated for their effect on sexual behavior and fertility and can therefore serve as basis for the identification of new chemical leads useful in sexual and erectile dysfunction.
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.
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.
This review presents an overview on plants identified to possess hair growth activity in various ethno-botanical studies and surveys of tradition medicinal plants. It also highlights the developments in hair rejuvenation strategies from 1926 till-date and reviews the potential of herbal drugs as safer and effective alternatives. There are various causes for hair loss and the phenomenon is still not fully understood. The treatments offered include both natural or synthetic products to treat the condition of hair loss (alopecia), nonetheless natural products are continuously gaining popularity mainly due to their fewer side effects and better formulation strategies for natural product extracts. Plants have been widely used for hair growth promotion since ancient times as reported in Ayurveda, Chinese and Unani systems of medicine. This review covers information about different herbs and herbal formulation that are believed to be able to reduce the rate of hair loss and at the same time stimulate new hair growth. A focus is placed on their mechanism of action and the review also covers various isolated phytoconstituents possessing hair growth promoting effect.
The petroleum ether extract of C. reflexa and its isolate is useful in treatment of androgen-induced alopecia by inhibiting the enzyme 5alpha-reductase.
