With therapeutic properties based on their chemical composition, essential oils—extracts from herbs, flowers, and other plant materials—have been used to treat symptoms and diseases for thousands of years. However, the term aromatherapy was not used until French chemist Gattefosse published a text in 1936. Clinical aromatherapy is defined as the use of essential oils for therapeutic purposes th...

Oral candidiasis causes pain in oral cavity or tongue. Antifungal drugs are commonly used for the treatment of candidiasis, however, there could be several problems such as side effects, drug resistance, or contraindication to concomitant use with drugs already taken. The development of substituting antimicrobial agents, which could be used internally or as gargling agents, is expected. Some es...

Aim: Present study was conducted to examine the modulatory effect of different essential oils on rumen fermentation pattern in vitro using wheat straw based diet (concentrate: wheat straw 50:50). Materials and Methods: Four essential oils i.e. cinnamon, garlic, oregano and rosemary oils were tested at concentration of 0, 30, 300 and 600 mg/litre (ppm) of total culture fluid using in vitro gas p...

Essential oils on the market were analyzed using GC-MS and the main ingredients of each essential oil were quantified. Analysis of the essential oil of Lavandula officinalis (lavender oil) showed that each sample had a different ratio of the contents of main ingredients, such as linalool, linalyl acetate, and camphor. In addition, some commercial lavender oils were analyzed by GC-MS for compari...

bioassays were conducted to assess the contact toxicity of two plant essential oils against adults of sitophilus granarius (l.) and tribolium confusum jacquelin du val. essential oils were extracted from seeds of carum copticum l. and cuminum cyminum l. contact toxicity was assessed by topical application and adult mortality was counted 1, 2, 6 and 24 h after exposure. bioassays were carried ou...

achillea millefolium belong to the asteraceae family and from genus achillea. in this study essential oils were extracted from all aerial parts via hydro distillation (hd) method by clevenger set . by using of gas chromatography/mass spectrometry ( gc-ms) technique the chemicals component essential oil were identified. about 41 components with were identified which encompassed 97.66 percent of ...

The essential oil was obtained by hydrodistillation and the identification and quantification of components were achieved with the use of GC-MS analysis. The antioxidant activity was evaluated by the method of sequestration of DPPH. Essential oils were used for study the cytotoxic front larvae of Artemia salina. In the evaluation of the antimicrobial activity of essential oils, we employed the ...

Subterranean termite infestations occur in every state in the contiguous United States and are responsible for damage to wooden structures in excess of two billion dollars (U.S.) annually. Essential oils have historically been used to repel insects. They have relatively low toxicity and some of them are exempt from regulation by the Federal Insecticide Fungicide and Rodenticide Act (FIFRA). Dev...

The aim of the study was to evaluate the antimicrobial activity of essential oils in vitro for possible application to reduce the content of microorganisms in the air of animal houses. The essential oils of Cymbopogon citrarus L. and Malaleuca alternifolia L. were screened against bacteria Staphylococcus aureus, Enterococcus faecium, Pseudomonas aeruginosa, Escherichia coli, Proteus mirabilis a...

background: plant extracts and oils may act as alternatives to conventional pesticides for malaria vector control. the aim of this study was to evaluate the larvicidal activity of essential oils of three plants of apiaceae family against anophe­les stephensi , the main malaria vector in iran. methods: essential oils from heracleum persicum , foeniculum vulgare and coriandrum sativum seeds were ...
