Investigating the Influence of 0.75% Ethanol Extract Gel from “Kaempferia galanga L Rhizoma” on Mild and Moderate Acne Vulgaris Among High School Students

Background: Acne vulgaris is a prevalent dermatological condition characterized by the inflammation of sebaceous follicles. This inflammation results in various clinical manifestations, including open and closed comedones, papules, pustules, nodules, and cysts, which predominantly appear on the face. The impact of acne vulgaris extends beyond physical symptoms, often affecting psychological well-being and quality of life, particularly among adolescents. Given this condition's widespread prevalence and significant implications, there is a pressing need for effective and accessible treatments. Objective: This study aimed to evaluate the impact of Kencur Rhizome Ethanol Extract Gel (Kaempferia galanga L. Rhizoma / KGR) on mild and moderate acne vulgaris lesions among high school students. Method: Twenty-four high school students were divided into three groups: Group 1 received 0.75% Kaempferia galanga rhizome ethanol extract gel, Group 2 received a combination gel of 0.75% Kaempferia galanga ethanol extract, and 75% benzoyl peroxide with 1% clindamycin gel, and Group 3 received 1% clindamycin gel. The number of subjects in each group was determined using the G Power application. The distribution of gels was randomly assigned using the “Randomly Assign Subjects to Treatment Group” application. Before treatment, blood samples were taken to measure IL-8 levels. After three weeks of treatment, bilateral facial photographs were taken: one with the right side tilted at 45 degrees and the other with the left side tilted at 45 degrees. Blood samples were collected again for IL-8 measurement, and high-resolution photographs of both sides of the face were taken to analyze acne lesions using the ImageJ application. Result: A combination of 0.75% KGR ethanol extract gel and 1% clindamycin gel significantly reduced the severity of AV lesions by affecting IL8 expression (p=0.042) in reducing the severity of mild and moderate AV lesions. For AV lesions using the ImageJ application, the administration of group 2 gel (a combination of 0.75% KGR ethanol extract gel and 1% clindamycin gel) has a significant effect on reducing the severity of mild and moderate degrees of whitehead or blackhead (p = 0.030) and nodules (p = 0.035) in acne vulgaris. Conclusion: A combination of 0.75% kencur rhizome ethanol extract gel and 1% clindamycin gel effectively alleviate acne vulgaris symptoms while also reducing inflammation of acne vulgaris lesions.

In Vitro Cytotoxicity and Antimicrobial Activity against Acne-Causing Bacteria and Phytochemical Analysis of Galangal (Alpinia galanga) and Bitter Ginger (Zingiber zerumbet) Extracts.

Galangal (Alpinia galanga (L.) Willd) and bitter ginger (Zingiber zerumbet (L.) Roscoe) are aromatic rhizomatous plants that are typically used for culinary purposes. These rhizomatous plants have many biological properties and the potential to be beneficial for pharmaceutics. In this study, we evaluated the antioxidant and antimicrobial activities, with a specific focus on acne-causing bacteria, as well as the phytochemical constituents, of different parts of galangal and bitter ginger. The rhizomes, stems, and leaves of galangal and bitter ginger were separately dried for absolute ethanol and methanol extractions. The extracts were used to evaluate the antioxidant activity using a DPPH radical scavenging assay (0.005-5000 μg/mL), antimicrobial activity against acne-causing bacteria (0.50-31.68 mg/mL), and in vitro cytotoxicity toward human keratinocytes and fibroblasts (62.5-1000 μg/mL), as well as analyses of bioactive phytochemicals via GC-MS and LC-MS/MS (500 ppm). The ethanol and methanol extracts of bitter ginger and galangal's rhizomes (BRhE, BRhM, GRhE, and GRhM), stems (BStE, BStM, GRhE, and GRhM), and leaves (BLeE, BLeM, GLeE, and GLeM), respectively, showed antioxidant and antimicrobial activities. The extracts of all parts of bitter ginger and galangal were greatly antioxidative with 0.06-1.42 mg/mL for the IC50 values, while most of the extracts were strongly antimicrobial against C. acnes DMST 14916, particularly BRhM, BRhE, GRhM, and GRhE (MICs: 3.96-7.92 mg/mL). These rhizome extracts had also antimicrobial activities against S. aureus TISTR 746 (MICs: 7.92-31.68 mg/mL) and S. epidermidis TISTR 518 (MICs: 7.92-15.84 mg/mL). The extracts of bitter ginger and galangal rhizomes were not toxic to HaCaT and MRC-5 even at the highest concentrations. Through GC-MS and LC-MS/MS analysis, phytochemicals in bitter ginger rhizome extracts, including zerumbone, tectorigenin, piperic acid, demethoxycurcumin, and cirsimaritin, and galangal rhizome extracts, including sweroside and neobavaisoflavone, were expected to provide the antioxidant and anti-microbial activities. Therefore, the results suggest that the bitter ginger and galangal extracts could be natural anti-acne compounds with potential for pharmaceutic, cosmetic, and aesthetic applications.

In vitro Antimicrobial Activity Test of Zingiber officinale var. rubrum Rhizome Extract against Methicillin-Sensitive Staphylococcus aureus (MSSA) and Methicillin-Resistant Staphylococcus aureus (MRSA)

Highlights: Staphylococcus aureus, particularly MRSA, had developed rapid resistance against antibiotics like beta-lactams. Red ginger is believed to be antibacterial against MSSA and MRSA in vitro. Red ginger rhizome extracts displayed weak activity against MSSA and MRSA. Abstract Introduction: Red ginger (Zingiber officinale var. rubrum) is a traditional herb that is believed to possess antibacterial properties. Throughout the years, Staphylococcus aureus has developed resistance to a broad range of antibiotics, including beta-lactams, particularly in the form of Methicillin-Resistant Staphylococcus aureus (MRSA). As treatment options dwindle, it is urgent to formulate novel antibiotics. This study aimed to examine the antibacterial activity of the ginger rhizome ethanol extract against Methicillin-Sensitive Staphylococcus aureus (MSSA) and MRSA. Methods: This study was performed according to the post-test-only control group design. Through a good diffusion assay, the anti-MSSA and anti-MRSA activity of the red ginger extract concentrations (100%, 50%, 25%, 12.5%, and 6.25%) was observed by measuring the diameter of the clear inhibition zones. Dimethyl sulfoxide (DMSO) and an antibiotic disc were added as control groups. Results: The red ginger extracts produced inhibition zones on both MSSA and MRSA. However, the antibacterial activity was considered weak (<12 mm). The concentration of the extract appeared to linearly affect its antibacterial activity against MSSA and MRSA. On MSSA, the 12.5% extract results differed significantly from those of the 100% and 50% extracts. Meanwhile, on MRSA, the extracts seemed to yield significantly different outcomes when compared to each other, except for the comparisons between 50%-25% and 12.5%-6.25%. Conclusion: Zingiber officinale var. rubrum rhizome extracts showed weak antibacterial activity against MSSA and MRSA.
