This experiment was carried out to obtain the maximum quantity of essential oil on the basis of harvesting time, cultivation regions & types, and drying methods. We have selected 6 native and introduced herbs viz. $Thymus$ $quinquecostatus$, $Agastache$ $rugosa$, $Chrysanthemum$ $indicum$, $Rosmarinus$ $officinalis$, $Chamaemelum$ $nobile$, and $Lavandula$ $stoechas$. The quantity of essential oil ranged from 0.06% to 3.46% in all six herbs. Native herbs produce 30.5% higher quantity of oil in comparison to introduced herbs. The quantity of essential oil obtained from $Lavandula$ $stoechas$ was 3.46%, followed by $Rosmarinus$ $officinalis$ 2.89%, while minimum in $Agastache$ $rugosa$ 0.60%. Higher quantity of essential oil obtained if they are cultivated under rain shelter culture (PE film) in comparison to open field conditions. Recovery of essential oil is always high if herbs flower in July. Semi-alpine region was found better than the plain region for herbs production. Quantity of oil is high if oil is extracted from fresh herbs followed by freezed herbs, shade dry and hot wind dry herbs. As far as plant part is concern flower produced maximum oil than any other part.

The selenium (Se) contents of 20 herbs, harvested in three areas in Korea, were analyzed. Many herbs had no Se. Angelica ($138.4{\mu}g \;Se{\cdot}kg^{-1}$ FW), caraway ($167.8{\mu}g \;Se{\cdot}kg^{-1}$ FW), chamomile ($116.6{\mu}g \;Se{\cdot}kg^{-1}$ FW), marjoram (158.7 and $132.6{\mu}g\;Se{\cdot}kg^{-1}$ FW), and oregano ($62.5{\mu}g\;Se{\cdot}kg^{-1}$ FW) accumulated Se as higher concentration compared with other plants. The Se content of herbs was dependent on the species, cultivars and areas. The status of Se uptake by herbs was investigated according to Se concentrations in hydroponics. During four weeks, before harvest of several herbs in greenhouse, sodium selenate ($Na_2SeO_4$) was added to the nutrient solution at concentrations of 2, 4, 6, and $8mg{\cdot}L^{-1}$. Field-mint accumulated Se too high, but external symptom of Se toxicity was not found. Essential oil content was generally proportionated to treated-Se concentration. The essential oil contents in basil and balm increased two to three times higher by sodium selenate treatment compared to non-treatment, but they did not show any linear relationship between essential oil contents and treated-Se concentration.

The growth and quality differences between common thyme(Thymus vulgaris L.) and lemon thym (Thymus$\times$citriodorus) were investigated. They were grown in a hydroponics culture system (DFT) with a nutrient solution developed by the European Vegetable R&D Center in Belgium. Nutrient solution ionic strength used were 1.2, 2.4, 4.8 and 7.2 mS.cm-1. The dry matter of two thymes were increased with increasing ionic strength, while shoot length, root length and fresh weight were decreased. Chlorophyll content was higher in lemon thyme, while vitamin C content and essential oil content were higher in common thyme. The essential oil content showed a similar trend as those of growth. The main compostion of essential oil were thymol and carvacrol in common thyme, and geraniol and $\alpha$-citral in lemon thyme. The highest content of these compounds was obtained in 1.2mS.cm-1 treatment. Consequently, the ionic strength of 1.2mS.cm-1 was suitable for the production of quality thymes.

This experiment was conducted to find out optimum substrate and concentration of nutrient solution for mass production of sweet basil by pot culture. Growth depending on concentration of nutrient solution was different to some extent; the growth of plants was usually better in one-fold and two-fold concentration of nutrient solution but three-fold one was poor. Plants grown in cocopeat showed better growth, but peatmoss gave an adverse effect. Sweet basil grown in substrate mixed with cocopeat and perlite (1:1, v:v) was highest in essential oil content. After all, cultural practice by one-fold concentration of herb nutrient solution in substrate mixed with cocopeat and perlite (1:1, v:v) was recommended for better growth and higher essential oil content of sweet basil.

The effects of inhaling three essential oils (lavender [Lavendular angustifolia], silver fir [Abies alba], and grapefruit [Citrus paradise]) against restraint stress were investigated in mice. Serum cortisol levels were significantly increased in the 1h-restraint group. Also, silver fir and grapefruit oils prevented the elevation of cortisol levels under experimental conditions. Inhalation of 10% lavender oil for 30 min before inducing stress significantly inhibited restraint-induced hypothermia. We also investigated the effects of restraint stress on triglycerides, total cholesterol, and high-density lipoprotein cholesterol. It was found that the concentration of triglycerides in the serum samples increased after restraint stress. Silver fir essential oil inhibited elevation of triglyceride levels. Taken all together, the correlation of herb essential oil inhalation against restraint stress in animals can partly be explained.

This study was conducted to evaluate appropriate selenate ion concentration for the production of high functional vegetables. Sodium selenate was treated 0, 2, 4, 6 and 8mg/$\ell$ using herb nutrient solution developed by European R & D Vegetable Center in Belgium. Low level of Na2se04 concentration increased the growth of wormwood, but high selenate concentration decreased the growth. Total chlorophyll content was increased by sodium selenate. The higher selenate ion concentration in the nutrient solution, the more total chlorophyll content was. The vitamin C content in wormwood was high at 2 and 4mg/$\ell$ treatment, showing good growth, at higher concentration, however, the vitamin C content decreased. At 4mg/$\ell$ selenate ion concentration, essential oil content of wormwood was best. But higher selenate ion concentration decreased essential oil content. The uptake of Se by the plant increased with the increase of selenate ion concentration.
