Whitening and anti-oxidant effects were observed in order to investigate the biological activations of Salvia plebeia herb ethanol extracts. No toxicity was found in both B16F10 melanoma cells and Raw 264.7 cells exposed to Salvia plebeia herb ethanol extracts for 48 hour. The extracts showed significant antioxidant activity in cell-free and cell-cultured system. In the DPPH radical assay, it removed dose-dependently DPPH radicals and showed 77.6% at $100{\mu}g/mL$. In the cells, it also significantly removed silica-induced ROS generation and LPS-induced NO production in a dose dependent manner. Using L-DOPA and L-tyrosine as a substrate, tyrosinase activity was inhibited using Salvia plebeia herb ethanol extracts in a dose-dependent manner. The supression occurred to be in the B16F10 melanoma cells, where dose-dependently inhibited Salvia plebeia herb ethanol extracts of $1{\mu}g/M$ ${\alpha}$-melanocyte stimulated hormone-induced melanin production and the inhibitory effect was 30.7% at a concentration of $100{\mu}g/mL$. This suggests that the Salvia plebeia herb ethanol extracts are usable for cosmetic product developments for anti-oxidant and whitening effects.

Objective: To investigate the possibility of hepatotoxicity by supplemental foods or folk herbs such as Salvia Plebeia R. Br. Methods: A hospitalized male patient with alcoholic liver disease and electrolyte imbalance had recovered, and then followed by rapid hepatic serum enzymes after taking S. Plebeia. This study monitored the clinical outcome and biochemical parameters. Result: A 58-year male had drunk frequently, which led to alcoholic steatohepatitis and hospitalization. Two weeks after his discharge from hospital, he felt nausea, dizziness, and mild difficulties in speech and walking, resulting in re-hospitalization at the Korean Medical Hospital. The symptoms disappeared on correction of the electrolyte imbalance suspected to have been caused by severe sweating while working in the outdoors, and the patient was discharged. During treatment and monitoring of his health as an outpatient, the serum hepatic enzyme rapidly elevated approximately 10-fold in hepatic enzymes; the enzyme levels fluctuated according to whether or not he was taking the boiled water of S. Plebeia. The RUCAM score was 12, which met the criteria for toxic hepatitis by S. Plebeia. His general condition and abnormal hepatic enzymes recovered with cessation of S. Plebeia and administration of Chungganplus syrup (CGX). Conclusion: This study reports the hepatotoxic risk of Salvia Plebeia, which is commonly used as a folk remedy in Korea.

As inhibitors of carbohydrate-digesting enzymes can prevent hyperglycemia that is known to cause many macrovascular complications, they may prove a useful adjunct to hypocaloric diets in patients with type 2 diabetes and obesity. Inhibitory activities of two hundred and fifteen kinds of medicinal herb extracts against $\alpha$-glucosidase (EC 3.2.1.20) and $\alpha$-amylase (EC 3.2.1.1) have been investigated in vitro. Adenophora triphylla, Aneilema keisak, and Morus bombysis significantly suppressed rat intestinal $\alpha$-glucosidase activity iu vitro. Porcine pancreatic amylase was efficiently inhibited by methanol extracts of Epimedium koreanum, Campsis grandiflora and Salvia plebeia. Methanol extract of Epimedium koreanum among the medicinal herbs tested showed the strongest inhibitory activity against porcine pancreatic $\alpha$-amylase with 0.1 mg/ML of $IC_{50}$/. The herb extract also improved glucose tolerance in ICR mice when loaded with 0.9 g soluble starch per kg body weight. Taken together, Epimedium koreanum merits further evaluation as a therapeutic measure.

The in-vitro eliminative effects of against three types of herbal extract and formalin Ichthyophthirius multifiliis were examined. All parasites were killed within one hour after exposure to the 500 fold dilution of the complex herb extract whereas the 10 fold dilution of the fertilized solution of Salvia plebeia R. Br. killed all parasites within one hour after exposure. The 5,000 fold dilution of the extracts of Ginkgo biloba leaves killed all parasites within one hour after exposure. As a comparative agent, formalin killed all parasites within one hour at 100 ppm. As the results, the extracts of Ginkgo biloba leaves extracts have the most eliminative ability against the parasite. No differences were found among different parasite density in eliminative effects of the three types of herbal extracts and formalin. Also there were no changes in the fish gill tissues after exposure for two hours to the 5,000 fold dilution of the extract of Ginkgo biloba leaves.

Seven native and four introduced herbs namely $Thymus$ $quinquecostatus$, $Chrysanthemum$ $zawadskii$ var. $latilobum$, $Rosmarinus$ $officinalis$, etc. were selected for analysis of the DPPH radical scavenging and anti-microbial activity of their extracts. These perennial herbs are classified as $Labiatae$ and $Compositae$ except for $Saururus$ $chinensis$ and can be propagated through seedling and cuttage. These edible herbs are used as medicinal as well as ornamental plants. Their extract has electron donating ability which ranges from 69.7 to 78.7% for native herbs and 67.4 to 75.4% for introduced herbs. Native herbs have higher (3.54%) average DPPH radical scavenging than introduced herbs. In native herbs, maximum DPPH radical scavenging activity was observed in $Agastache$ $rugosa$ (78.7%) followed by $Saururus$ $chinensis$ while $Chamaemelum$ $nobile$ showed highest activity among the introduced herbs. Many herbs viz. $Saururus$ $chinensis$, $Chrysanthemum$ $zawadskii$ var. $latilobum$ and $Solidago$ $virga-aurea$ var. $gigantean$ showed excellent anti-microbial activity against gram positive $Enterococcus$ $faecalis$, maximum (80.0%) by $Saururus$ $chinensis$. Other herbs viz. $Solidago$ $virga-aurea$ var. $gigantea$, $Chrysanthemum$ $zawadskii$ var. $latilobum$, $Salvia$Salvia $plebeia$, $Chrysanthemum$ $indicum$, $Rosmarinus$ $officinalis$, $Chamaemelum$ $nobile$ and $Lavandula$ $stoechas$ showed anti-microbial activity against gram negative $Citrobacter$ $freundii$. Especially, the inhibition of colony growth of $Citrobacter$ $freundii$ was highest in the extract of $Chrysanthemum$ $zawadskii$ var. $latilobum$, and $Chamaemelum$ $nobile$.
