Two experiments were conducted to study the performance and carcass characteristics of Hanwoo (Korean native beef cattle) steers (Experiment 1) and the nutrient digestibility of sheep (Experiment 2) when the animals fed diets containing four levels of dried wormwood (Artemisia sp.). For both experiments the animals were given a basal diet consisting of rice straw and concentrate mixed at 3:7 ratio (on DM basis). In Experiment 1, the treatments were designed as a completely randomized design with two feeding periods. Steers were allotted in one of four dietary treatments, which were designed to progressively substitute dried wormwood for 0, 3, 5 and 10% of the rice straw in the basal diet. Bodyweight gain and average daily gain (ADG) of Hanwoo steers fed diets containing the 5 and 10% wormwood inclusion were greater (p<0.05) than the 3% wormwood-feeding group. Total and daily intakes of roughage and concentrate were not altered by all levels of dried wormwood inclusion. However, the 10% dried wormwood inclusion led to increased total feed intake (p<0.05) compared with that of the 0 and 3% of dried wormwood inclusion. Carcass weight, carcass yield and backfat thickness were not altered by dried wormwood inclusion. The highest level of dried wormwood inclusion resulted in significantly increased (p<0.05) loin-eye area compared with the 0 and 5% levels of dried wormwood inclusion. Experiment 2 was designed by a $4{\times}4$ Latin square with four periods. Sheep were allocated in one of four dietary treatments as same as in Experiment 1. Digestibilities of DM and TDN were significantly increased (p<0.05) in sheep fed the diet containing all three levels of dried wormwood inclusion compared with the control treatment. Digestibilities of CP and crude fiber in the 5% dried wormwood inclusion highly increased (p<0.05) up to 8.2 and 5.5% respectively relative to the control treatment. The palatability was significantly improved (p<0.05) by the 5% dried wormwood inclusion compared with the control treatment. It is concluded that feeding diets containing dried wormwood substituted for equal weights of rice straw at 5 and 10% levels would be anticipated to provide better quality roughage for beef cattle production and higher income for beef cattle producers.

The therapeutic use of the wormwood plant Artemisia absinthium L. dates back to at least Roman times. There are more than 200 plants in the genus Artemisia- including southern wormwood, petite wormwood and Grande wormwood and encompasses about 500 species. The best-known species of wormwood is Artemisia absinthium, native to temperate Eurasia and North Africa and is branded for its extreme bitterness. It is a magical greens booze used as carminative to support healthy appetite, balances healthy flora, cleanse the digestive tract of parasite and toxins. It possesses anti-inflammatory, immunomodulatory, hepatoprotective, anti-helminthic and anti-depressant activity. Thujone excites nervous system when taken in small amount. Due to contrary history of wormwood, its application in individuals should be preceded by a thorough and cautious risk-benefit analysis. In this appraisal an attempt is done to validate scientifically, mentioned therapeutic potential of Artemisia absinthium in classical Unani literature using PubMed, Science Direct researches.

An experiment was conducted to examine the performance and carcass characteristics of Hanwoo (Korean native beef cattle) heifers and the fatty acid composition of muscle tissues of the heifers when the animals fed diets containing four levels of dried wormwood (Artemisia sp.). For the experiment the animals were given a basal diet consisting of rice straw and concentrate mixed at 3:7 ratio (on DM basis). The treatments were designed as a completely randomized design with two feeding periods. Heifers were allotted in one of four dietary treatments, which were designed to progressively substitute dried wormwood for 0, 3, 5 and 10% of the rice straw in the basal diet. There was no difference in body weight gain throughout the entire period between the treatment groups. Feed conversion rate was improved (p<0.05) only by the 3% dried wormwood inclusion treatment compared with the basal treatment. Carcass weight, carcass yield and backfat thickness of all treatment groups were not altered by wormwood inclusion. The 5% dried wormwood inclusion significantly increased (p<0.05) the size of loin-eye area over the other treatments. The higher levels (5 and 10%) of dried wormwood inclusion resulted in the higher (p<0.05) water holding capacity (WHC) in loin than the lower levels (0 and 3%) of wormwood inclusion. The redness ($a^*$) and yellowness ($b^*$) values of meat color were significantly lower (p<0.05) in the top round muscle of heifers fed the diet containing 3% dried wormwood. There was a profound effect of the progressively increased intake of dried wormwood led to the linear increase of unsaturated fatty acid content and the linear decrease of saturated fatty acid content in the muscle tissues of Hanwoo heifers. It is concluded that the feeding diets containing dried wormwood substituted for equal weights of rice straw at 5% levels would be anticipated to provide better quality roughage for beef heifer production and economical benefits for beef cattle producers.

This study was conducted to evaluate the shoot height at which the yield and nutritive value of wormwood (Artemisia montana) is optimized in order to provide information on its potential to support animal production (Experiment 1). A second objective was to determine how the essential oil (EO) concentration in wormwood hay and silage differ (Experiment 2). In Experiment 1, Artemisia montana was harvested at five different shoot heights (20, 40, 60, 80 and 100 cm) from triplicate $1.8{\times}1.8m$ plots. Dry matter (DM) yield was measured at each harvest date and the harvested wormwood was botanically separated into leaf, stalk and whole plant fractions and analyzed for chemical composition and in vitro dry matter digestibility (DMD). Values for total digestible nutrients (TDN), digestible energy (DE) and metabolizable energy (ME) were subsequently calculated using prediction equations. Dry matter yields of stalk and whole plant increased linearly (p<0.001) and leaf yield increased quadratically (p<0.01) with shoot height, whereas the leaf/stalk ratio decreased linearly (p<0.001). As shoot height increased, there was a linear increase (p<0.001) in leaf DM, ether extract (EE) and neutral detergent fiber (NDF) contents and a quadratic increase (p<0.05) in leaf acid detergent fiber (ADF) and nitrogen free extract (NFE) contents, and stalk and whole plant DM (p<0.001), organic matter (OM, p<0.01 and p<0.05), NDF (p<0.001 and 0.05) and NFE (p<0.05) contents. However, there were decreases in leaf crude protein content (CP, quadratic, p<0.001) and stalk and whole plant EE content (linear, p<0.001), CP (quadratic, p<0.05) and ash (quadratic, p<0.05) contents. Digestibility of DM and TDN, and DE and ME value in leaves were not affected by increasing shoot height, but these measures linearly decreased (p<0.001) in stalk and whole plant. In Experiment 2, the hay had higher DM and CP concentrations, but lower EE concentration than the silage. Essential oil (EO) content in wormwood silage (0.49 g/100 g DM) was higher (p<0.05) than that in wormwood hay (0.32 g/100 g DM). Wormwood hay contained 25 essentail oils (EO) including camphor (10.4 g/100 g), 1-borneol (11.6 g/100 g) and caryophyllene oxide (27.7 g/100 g), and wormwood silage had 26 EO constituents including 3-cyclohexen-1-ol (8.1 g/100 g), trans-caryophyllene (8.6 g/100 g) and ${\gamma}$-selinene (16.8 g/100 g). It is concluded that the most ideal shoot height for harvesting wormwood is 60 cm based on the optimization of DM yield and nutritive value. Wormwood silage had a greater quantity and array of EO than wormwood hay.

The compositional changes of wormwood (Artemisia princeps var. orientalis) essential oils were studied under 4 different storage conditions i.e., being exposed to air at 20 and $40^{\circ}C$. Sixty-four volatile compounds consisting of 24 terpene hydrocarbons, 18 alcohols, 11 ketones, 6 esters, 1 aldehyde, 2 hydrocarbons, and 2 oxides were identified on the basis of their mass spectra characteristics and retention indices in original wormwood essential oils. Identified compounds constituted 80.53% of the total peak area. Borneol (12.13%) was the most abundant compound, followed by $\alpha$-thujone (8.66%), T-cadinol (6.67%), and 1,8-cineole (6.21%) in original wormwood essential oils. Under the condition of $40^{\circ}C$ of temperature with the cap being opened for 3 min everyday respectively during 6 months of storage, the total amount of functional groups in essential oil determined by peak area percent were decreased by 79.45%, at most. The total level of monoterpene hydrocarbons decreased markedly in the aerobic condition and high temperatures. Whereas the total level of esters increased significantly. Wormwood essential oils were stored in experimental conditions, with the changes in the volatile compounds of essential oils being accelerated by high temperatures and contact with the atmosphere.

Dyeing fastness and antibiosis effects of fabrics dyed with wormwood, which has been used in folk medicines and dietary life in Korea for a long time, were studied through dyeing small overcoats, which are used as diapers, with wormwood extract. As for the dying fastness test results, the fastness of decoloration was not that good but the pollution level showed a relatively positive result. As for the antibiosis effect results, the antibiosis of the dyed sample was better than the original sample on 3 kinds of bacteria, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis and on 2 kinds of the fungi(Eumycetes). Aspergillus niger and Candida albicans. Especially, the sample that was mordant with CaCl2 and FeSO4·7H2O showed the best antibiosis effect. On the other hand, the sample that showed the best antibiosis effect was the refined fabric, which is a fabric that is not dyed.
