Oil Of Eucalyptus
Oil Of Eucalyptus Uses, Dosage, Side Effects, Food Interaction and all others data.
Oil Of Eucalyptus is a distilled oil derived from the leaves of the tree Eucalyptus. It is shown to be effective in reducing pain, swelling, and inflammation via its modulatory effect on the immune response. It is also shown to exhibit antibacterial activity against some bacterial species and cough suppressant actions. Oil Of Eucalyptus can be applied directly to the skin for pain and swelling of respiratory tract mucous membranes, joint pain, genital herpes, and nasal stuffiness.
Lipophilic monoterpene formulations of eucalyptus oil appear to be readily absorbed orally, with a primarily oxidative metabolism that might necessitate induction of the cytochrome P450 enzyme system and subsequent urinary excretion . Gastrointestinal absorption of eucalyptus appears to be rapid and may be enhanced by the intake of lipids and milk. 1,8-cineole (which makes up to as much as 90% of most commonly used cineole-based eucalyptus oils) has also been found in vitro and in animals to possess cytochrome P450 inducing activity .

Uses
Oil Of Eucalyptus is an ingredient used in a variety of natural health products.
As an active agent, eucalyptus oil has been indicated for relief of the symptoms of catarrhal colds, and/or the relief of the symptoms of minor muscular sprains and cramps .
Oil Of Eucalyptus is also used to associated treatment for these conditions: Cough, Infection, Itching caused by Insect Bites, Nasal Congestion, Rash caused by Insect Bites, Soreness, Muscle, Infection in minor cuts, scrapes, or burns, Itching skin, Minor aches and pains, Topical Antisepsis
How Oil Of Eucalyptus works
The general consensus is that the exact mechanism of action of eucalyptus oil is largely unknown at this time but comprises various hypotheses from various studies.
Cineol containing preparations of eucalyptus oil may contain up to 80% (or more) 1,8-cineole and is one of the most common types of eucalyptus oil formulations used. As an active agent indicated for relieving certain cold symptoms and/or certain muscular sprains and cramps, it is believed that eucalyptus oil may possess some antimicrobial and anti-inflammatory activities.
Some in vitro studies of human blood monocytes suggest a dose-dependent effect of eucalyptus oil to elicit significant inhibition of multiple cytokines, perhaps in the treatment of airway inflammation . Moreover, other studies in animal models discuss the possibility of eucalyptus oil demonstrating anti-inflammatory and anti-nociceptive effects that potentially account for inhibiting the formation of prostaglandins and cytokines by stimulated monocytes in vitro .
Furthermore, additional studies have observed eucalyptus oil anti-viral activity against herpes simplex virus (HSV-1, HSV-2) in cell cultures as well as the demonstration of broad antimicrobial activity of eucalyptus medicinal plant extracts against Alicyclobacillus acidoterretris, Bacillus cereus, E. coli, Enterococcus faecalis, MRSA, Propionibacterium acnes, S. aureus, fungus including C. albicans isolates, Trichophyton mentagrophytes, and other Gram-positive bacteria. Specific activity against periodontopathic bacteria, such as Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, Fusobacterium nucleatum, Streptococcus mutans, and Streptococcus sobrinus has also been observed .
Toxicity
Overdose with eucalyptus oil may result in epigastric burning, nausea and vomiting, dizziness, muscular weakness, mitosis, tachycardia, a sensation of suffocation, cyanosis, ataxia, pulmonary damage, delirium, convulsions, CNS depression, coma. Deaths have been recorded from doses as low as 3.5 ml.
The given oral LD50 for rats is 2480 mg/kg
Food Interaction
No interactions found.Volume of Distribution
Studies have determined a large terminal volume of distribution for cineole or eucalyptol (which makes up to as much as 90% of most commonly used cineole-based eucalyptus oils) of 27 l/kg in brushtail possum (Trichosurus vulpecula) .
Elimination Route
Common monoterpenoid compound preparations of eucalyptus oil have been observed to be readily absorbed after dermal application, likely due to their lipophilic character . Although maximal plasma levels were demonstrated in as short a time period as 10 minutes even with thicker preparations like eucalyptus oil ointments, like many other topically applied agents, the extent of absorption is also likely largely dependent upon additional factors like the size of treated skin area, patient skin condition(s), concentrations of the applied substance, and time of exposure to the substance .
Currently, more data regarding the oral absorption of eucalyptus would be useful, given the relative lack of existing information . Lipophilic monoterpene compound formulations of eucalyptus oil seems to be readily absorbed orally . Regardless, there is some data that suggests that the upper part of the gastrointestinal tract has no particularly significant role in the absorption of cineole based eucalyptus oil .
Pulmonary absorption of eucalyptus oil is also possible although little information exists regarding this element at the moment. Nevertheless, 1,8-cineol (which makes up to as much as 90% of most commonly used cineole-based eucalyptus oils) appears to be well absorbed via inhalation with peak plasma levels observed reportedly at 18 minutes .
Given the three main constituents from Eucalyptus globulus Labill fruits, the intestinal absorption of macrocarpal A (M-A), macrocarpal B (M-B), and cypellocarpa C (Cy-C) is predominantly via passive diffusion while Cy-C demonstrates some partly ATP-dependent absorption .
Half Life
Studies have determined a terminal half-life for cineole or eucalyptol (which makes up to as much as 90% of most commonly used cineole-based eucalyptus oils) of approximately 7h in brushtail possum (Trichosurus vulpecula) .
Clearance
Studies have determined a high clearance rate for cineole or eucalyptol (which makes up to as much as 90% of most commonly used cineole-based eucalyptus oils) of 43 ml/min/kg in brushtail possum (Trichosurus vulpecula) .
Elimination Route
Studies suggest the route of elimination for cineole or eucalyptol (which makes up to as much as 90% of most commonly used cineole-based eucalyptus oils) in brushtail possum (Trichosurus vulpecula), rats, and rabbit subjects as being in the urine .
