Eugenol / ˈ j uː dʒ ɪ n ɒ l / is an allyl chain-substituted guaiacol, a member of the allylbenzene class of chemical compounds. [2] It is a colorless to pale yellow, aromatic oily liquid extracted from certain essential oils especially from clove, nutmeg, cinnamon, basil and bay leaf.
Oil of clove, also known as clove oil or eugenol, is an essential oil extracted from the clove plant, Syzygium aromaticum. [1] [2] Clove oil is commonly used in aromatherapy and for flavoring food, tea, and toothpaste. [2] [3] In alternative medicine, it may be used as a topical medication to relieve toothache.
General anaesthetics can be administered either as gases or vapours (inhalational anaesthetics), or as injections (intravenous or even intramuscular).All of these agents share the property of being quite hydrophobic (i.e., as liquids, they are not freely miscible—or mixable—in water, and as gases they dissolve in oils better than in water).
An inhalational anesthetic is a chemical compound possessing general anesthetic properties that is delivered via inhalation. They are administered through a face mask, laryngeal mask airway or tracheal tube connected to an anesthetic vaporiser and an anesthetic delivery system .
The Meyer-Overton correlation for anaesthetics. A nonspecific mechanism of general anaesthetic action was first proposed by Emil Harless and Ernst von Bibra in 1847. [9] They suggested that general anaesthetics may act by dissolving in the fatty fraction of brain cells and removing fatty constituents from them, thus changing activity of brain cells and inducing anaesthesia.
Carbon dioxide (CO 2) is an abundant gas produced as the final product of glucose metabolism in animals. CO 2 anesthesia is most frequently used for anesthetizing flies. [2] But it has also been considered as a fast acting anesthetic in small laboratory animals. [3]
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...
Leaves of the coca plant (Erythroxylum novogranatense var. Novogranatense), from which cocaine, a naturally occurring local anesthetic, is derived [1] [2]. An anesthetic (American English) or anaesthetic (British English; see spelling differences) is a drug used to induce anesthesia — in other words, to result in a temporary loss of sensation or awareness.
