Parkinson's disease a futile entangle of Mankind's credence on an herbal remedy: A review.

Parkinson's disease (PD) is a disease of the human nervous system with an onset, in the sixth and seventh decades of the human life. Chiefly perceived as progressive degeneration of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc) with the ensued loss of dopamine in the striatum and the presence of Lewy bodies, consisting of α-synuclein agglomeration. In which the neuronal bridge between substantia nigra and striatum plays an advent role in the motor system. Dilapidation of these neurons results in dopamine depletion which in-turn makes hay to PD. Eventually, the etiology and pathogenesis of PD were still on a hike of dilemma. Traditional Chinese medicine (TCM), including Chinese herbal remedies, acupuncture, and manipulative therapies, is commonly used as an adjunctive therapy in different diseases, particularly neurological diseases, in Asian countries. Additionally, TCM might improve the prognoses and the quality of life of patients with PD because it induces less adverse drug reactions. The present review describes research on the various neuroprotective components and herbal extracts from herbal medicines in the context of addressing the effects of PD.

Evaluation of three medicinal plants for anti-microbial activity.

Herbal remedies have a long history of use for gum and tooth problems such as dental caries. The present microbiological study was carried out to evaluate the antimicrobial efficacy of three medicinal plants (Terminalia chebula Retz., Clitoria ternatea Linn., and Wedelia chinensis (Osbeck.) Merr.) on three pathogenic microorganisms in the oral cavity (Streptococcus mutans, Lactobacillus casei, and Staphylococcus aureus). Aqueous extract concentrations (5%, 10%, 25%, and 50%) were prepared from the fruits of Terminalia chebula, flowers of Clitoria ternatea, and leaves of Wedelia chinensis. The antimicrobial efficacy of the aqueous extract concentrations of each plant was tested using agar well diffusion method and the size of the inhibition zone was measured in millimeters. The results obtained showed that the diameter of zone of inhibition increased with increase in concentration of extract and the antimicrobial efficacy of the aqueous extracts of the three plants was observed in the increasing order - Wedelia chinensis < Clitoria ternatea < Terminalia chebula. It can be concluded that the tested extracts of all the three plants were effective against dental caries causing bacteria.

Efficacy and safety of two polyherbal combinations: E-MA-H and E-MA-HP in male sexual dysfunction.

Efficacy and safety of 2 herbal products--E-MA-H at 2 dose levels, low (HLD) and high (HHD), and E-MA-HP (HP) capsules--versus placebo (PL) was evaluated in subjects with male sexual dysfunction. Males aged 21-60 with erectile dysfunction, premature ejaculation, or other form of sexual dysfunction were studied in this triple-blind, randomized, placebo-controlled, parallel-groups trial. Subjects received any one of the following 4 interventions: E-MA-H 2 capsules at night (HLD) for 60 days; E-MA-H 2 capsules twice daily for 30 days, followed by 2 capsules at night for 30 days (HHD); E-MA-HP (HP) 2 capsules twice daily for 60 days; or placebo (PL) 2 capsules twice daily for 60 days. All dosage regimens were standardized to 2 capsules twice daily by using 2 matching placebo capsules as the morning dose for HLD and on days 31-60 for HHD. Efficacy outcome measures were the international index of erectile function; index for premature ejaculation; erectile dysfunction inventory of treatment satisfaction; subjects' and investigators' global assessment. Safety was assessed through adverse events; hematology; blood chemistry. Of 148 subjects enrolled, 1 was excluded from analysis; data on the intention-to-treat population of 147 (PL = 36, HLD = 38, HHD = 37, HP = 36) were analyzed. There was a significant (P < 0.01) increase in the total international index of erectile function score (mean ± SEM) in subjects receiving HLD (16.28 ± 1.39), HHD (15.40 ± 1.22), and HP (18.55 ± 1.36) compared with PL (6.83 ± 1.52). The same pattern was seen with increase in index for premature ejaculation scores: HLD (9.68 ± 1.17), HHD (10.27 ± 1.05), HP (11.36 ± 1.20) versus PL (3.77 ± 1.04). There was no significant difference in effect among the active treatment groups. The incidence of adverse events was similar in all the groups. Laboratory evaluations did not show any clinically significant abnormality in any of the groups. Treatment with HLD, HHD, and HP is well tolerated, and more effective than placebo (P < 0.01), in subjects with erectile dysfunction, premature ejaculation, and other forms of sexual dysfunction.
