Seasonal Changes in the Volatile Oil and Cineole Contents of Five Eucalyptus Species Growing in Morocco

Abstract: The effect of harvesting period on the oil production was examined on five Eucalyptus species (E. camaldulensis, E. globulus, E. globulus ssp. maidenii, E. melliodora and E. bosistoana) of Moroccan origin. For some species such as E. camaldulensis, E. globulus and E. globulus ssp. maidenii, the oil yield seemed to depend on the harvesting season. The period ranging from June to October gave the best yield with a maximum in June. The 1,8-cineole content of Eucalyptus oil may also vary during the year. This was observed in the case of E. globulus and E. melliodora, although the observed changes were rather random. The month for maximum 1,8-cineole content varied depending upon the species.

Enhancing effect of essential oils on the penetration of 5-fluorouracil through rat skin.

Abstract: Three essential oils as penetration enhancers for 5-fluorouracil (5-FU) were studied using excised rat skin. The oils used were eucalyptus, peppermint and turpentine. Azone was used for comparison. The enhancing effect of the oils was found to be less than that of azone, but all the oils used enhanced the permeation of 5-FU. Eucalyptus oil was found to be the most active, causing about 60 fold increase, while peppermint and turpentine caused 46 and 28 fold increase, respectively. Eucalyptus oil was further studied by grading it into 5 fractions according to difference in boiling points. It was found that their activities increased as their boiling point increased. With all enhancers increased partition coefficients were observed but the diffusion coefficient values obtained were comparatively higher. The mode of action of these accelerants may be described by combined processes of partition and diffusion, the diffusion process being dominant.

Abstract: A disinfecting and insecticidal composition comprising: (a) 5-25 % by volume a wetting agent/surfactant; (b) 10-40 % by volume an alcohol; (c) 0.25-14 % by volume a combination of Australian Tea Oil (Melaleuca Oil) and Eucalyptus Oil; (d) water.

Poison ivy treatment composition and method of use

Abstract: A composition and method are described for the treatment of allergic contact dermatitis, such as poison ivy, poison oak, and poison sumac. The composition includes linseed oil, an astringent such as alum powder, a starch such as cornstarch, an essential oil such as eucalyptus oil, and a citrus oil such as orange oil. The method includes applying the treatment composition to an affected area of skin, preferably once to twice per day.

Medicine composition for pain relief

Abstract: PURPOSE: To obtain an analgesic medicine composition containing a eucalyptus oil or a eucalyptus extract as an active ingredient. CONSTITUTION: The analgesic medicine composition contains a eucalyptus oil or a eucalyptus extract as an active ingredient. The analgesic medicine composition may be prepared into injection preparations, exodermis-coating preparations or oral administration preparations by conventional methods as such or after compounded with various other ingredients. The eucalyptus oil or extract is compounded in an amount of 0.1-100wt.%, preferably 0.1-10wt.%, in the case of injection preparations or in an amount of 0.1-100wt.%, preferably 3-20wt.%, in the case of the exodermis-coating preparations. The administration is performed at a dose of 100-50000mg, preferably 1000-5000mg, based on the eucalyptus oil or extract once to three times a day for an adult in the case of the injection preparations. The administration is performed at a dose of 500-3000mg, preferably 500-1000mg, based on the eucalyptus oil or extract once to three times a day, when the analgesic medicine composition is administered as the exodermis-coating preparations, e.g. when the composition is administered with a spray on an adult.
