Aldose reductase (AR) is a critical enzyme in the development of the diabetic complications. AR, the first enzyme in the polyol pathway, catalyzes the reduction of the aldehyde form of glucose to sorbitol with concomitant conversion of NADPH to $NADP^+$. None of aldose reductase inhibitor (ARI) has achieved worldwide use because of limited efficacy or undesirable side effects. Therefore, evaluating natural sources for ARI potential may lead to the development of safer and more effective agents against diabetic complications. Forty eight Chinese herbal medicines have been investigated for inhibitory activities on AR. Among them, seven herbal medicines, Buddleja officinalis (whole plant), Lonicera japonica (leaf and flower), Polygonum aviculare (aerial part), Polygonum aviculare (whole plant), Salvia miltiorrhiza (root), Schisandra chinensis (stem), and Zanthoxylum armatum (leaf and stem) exhibited a significant inhibitory activity against AR. Particularly, L. japonica and P. aviculare showed two times more potent inhibitory activity than the positive control, 3,3-tetramethyleneglutaric acid (TMG).

Objectives: To summarize and make a reference number of herbal plant-derived antioxidant researches worldwide. Methods: We surveyed all papers of antioxidant-focused studies using plants in PubMed database as "herbal plant AND antioxidant" of Default Tag "Title". The type of materials used in the studies, formation of experiments, frequency of herbal plants studied and their actions, and main study subjects were analyzed. Results: The number of studies on herbal plant-related antioxidant effects have increased worldwide since 2000. Studies have been performed using mainly single plant and single compounds for medical disorders such as immunity, heart/blood, liver, and central nerve functions. The list of plants frequently includes SalviamiltiorrhizaBge.,GinkgobilobaL., ScutellabaicalensisGeorgi.,and so on. Most of these plants have strong effects against oxidative stress and also against free radicals and increase the activities of antioxidant enzymes. Conclusion: This study produced an overview of previous research on antioxidant-focused herbal plants. This result will provide useful information for the field of Korean traditional medicine for the development of drugs related to antioxidants.

Objectives : Term standardization is the most important for knowledge information in every study. There are several tries to make terminology standards in Korean Traditional Medicine(KTM). We, authors took a review on romanized prescription nomenclature of main titles in Herbal Formula Science to criticize the ways of romanized prescription nomenclature. Methods : We extract romanized prescription name from Vol. 11, No. 1 to latest Issue Vol. 21, No. 1, Herbal Formula Science. Results : The Korean Academy of Oriental Medicine Prescription has guideline for romanized prescription nomenclature. However, only 6 out of 147 romanized prescription name are confirmed with guideline. In addition, 58 out of 142 names are italicized without guideline. Also there are several ways of marking for prescription names. Conclusions : For making knowledge information and easy searching for terms, we need normative regulations for romanized prescription nomenclature by the Society of Korean Medicine level.

Objectives This study aimed to review clinical studies on traditional Korean medicine treatment for medial collateral ligament injury of the knee. Methods Clinical studies on Korean traditional medicine treatment of medial collateral ligament injury were conducted. We used five Korean online databases (OASIS, KISS, RISS, DBPia, and ScienceOn) and three foreign databases (PubMed, Cochrane Library, and CNKI). Out of 99 studies that were found, we excluded repeated articles, studies that were not related to Korean medicine, and those not relevant to the topic of the study. Results Ten randomized controlled trials and 20 case studies were selected. Eight traditional Korean medicine treatments, including acupuncture, herbal medicine, chuna, and herbal ointment, were used in these studies. The most commonly used treatment was found to be acupuncture. Conclusions Our study showed that traditional Korean medicine for medial collateral ligament injuries was effective. However, there were some limitations. Further clinical studies and randomized controlled clinical trials are needed for more evidence on Korean traditional medicine.

Objective: This study was aimed to report the therapeutic effects of herbal medicine on chemotherapy-induced peripheral neuropathy (CIPN). Methods: The prior studies were searched from the databases included PubMed, Cochrane Library, EMBASE, CNKi, CiNii, KISS, NDSL, KMBASE, and OASIS until September 2020. The main search keywords were chemotherapy, peripheral neuropathy, and herbal medicine, and only randomized controlled trials that analyzed the therapeutic efficacy of herbal medicine were included. The Cochrane's Risk of Bias was used for assessment of the risk of bias and the Review Manager 5.3 program was used for meta-analysis. Meta-analyses were grouped by the administration routes of herbal medicines (oral administration or topical use). Results: Nine studies with a total of 563 participants were included. Compared with usual care, the effective rate was higher in oral administrated herbal medicine (RR 1.67, 95% CI 1.25 to 2.23; p<0.001, I2=31%). In addition, topical herbal medicine showed an significantly higher effective rate than placebo (RR 2.20, 95% CI 1.52 to 3.18; p<0.001, I2=0%) and usual care (RR 2.24, 95% CI 1.74 to 2.89; p<0.001, I2=66%). There was no severe adverse effect in all participants. Conclusions: Herbal medicine appears to improve neuropathy caused by chemotherapy in cancer patients more than conventional therapy of CIPN. However, as there is heterogeneity between the included studies and a lack of blinding, further well-designed researches are more needed.

Enhanced formation and accumulation of advanced glycation end products (AGEs) have been implicated as a major pathogenesis process leading to diabetic complications, normal aging, atherosclerosis and Alzheimer's disease. In our ongoing project to discover novel treatments for diabetic complications from natural sources, we have investigated on the inhibitory activity of 67 ethanol extracts from 57 Korean herbal medicines against the formation of AGEs in vitro. Of these, 22 extracts were found to have a significant AGEs inhibitory activity ($IC_{50}$<50 ${\mu}g$/ml) compared with aminoguanidine ($IC_{50}$=75.98 ${\mu}g$/ml). Particularly, 6 extracts from 3 herbal medicines, Castanea crenata (flower, leaf, bark-twig), Acer tatarium subsp. ginnala (fruit) and Sapium japonicum (leaf, twig) showed (approximately 8-17 fold) stronger inhibitory activity than that of aminoguanidine.

Objective: The purpose of this study was to collect and evaluate evidence of herbal medicine treatments for the residual effects of COVID-19. Methods: Nine electronic databases, namely PubMed, Science Direct, CINAHL, CNKI, Wanfang, J-STAGE, CiNii, OASIS, and Science ON, were searched with the following keywords: 'COVID-19'; 'sequelae'; 'Convalescence' for 'P (Population)' and 'Medicine, Chinese Traditional'; 'Korean medicine'; 'Herbal medicine' for 'I (Intervention)'. For the selected studies, various clinical data were extracted including patient symptoms, pattern identification, herbal medicines prescribed, and treatment results. Results: A total of nine clinical studies were identified (two case control trials; one case series; and six case reports). Various residual symptoms had been detected in the recovery stage of COVID-19 with the most commonly used pattern identifications being deficiency in both lung and spleen and in both qi and yin. Any herbal medicine prescriptions were written using these patterns. We found several reports of the positive effect of herbal medicines in that it improved symptoms, lung function, and lung inflammation. No adverse events were reported. Conclusions: The results indicate that treatment with herbal medicines has a possible therapeutic effect on the residual symptoms of COVID-19. Large-scale studies are necessary to confirm the effectiveness of these approaches.
