Eucalyptus is native to Australia, and contains about 600 species. Of all the i
species, Eucalyptus globulus is the most widely cultivated in subtropical and Mediterranean regions. Eucalyptus leaves are traditionally used to heal wounds ?
and fungal infections. Leaf extracts of eucalyptus have been approved as food I
additives, and are also being currently used in cosmetic formulations. Recently, }
attention has been focused on the medicinal properties of these extracts. Research !
data has demonstrated that the extracts exhibited various biological effects, such
as anti-hyperglycemic (Gray and Flatt 1998) and antioxidant (Lee and Shibamoto I
2001) activities. It has been reported that macrocarpals from E. macrocarpa
(Yamakoshi et al. 1992) and grandinol from E. perriniana (Nakayama et al. 1990)
were effective against Gram-positive bacteria {Staphylococcus aureus. Bacillus
subtilis). Its volatile oil is obtained by steam distillation and rectification from the
fresh leaves or the fresh terminal branches. Eucalyptol (1, 8-cineole) is the active ingredient of the eucalyptus oil, responsible for its various pharmacological
actions. Oil of eucalyptus has been traditionally used in Ayurveda as an antiseptic
and for respiratory tract infections.
Chamomile oil {Chamomile recutita) is an annual herb that belongs to the |
Asteraceae (Compositae) family. The name "chamomile" comes from two Greek [
words meaning "ground apple" for its apple-like smell. German chamomile is an |

tall. Its flower head is one inch in diameter and has a hollow conical center
covered with tiny yellow florets surrounded by silver-white to cream colored I
florets. It has erect branching with finely divided leaves. Its primary uses are as a
sedative, anxiolytic and antispasmodic, and as a treatment for mild skin irritation (
and inflammation. Chamomile's main active constituents are chamazulene,
apigenin, and bisabolol. It possess anti-inflammatory, vulnerary, deodorant,
bacteriostatic, antimicrobial, anti-catarrhal, carminative, sedative, antiseptic, and
spasmolytic properties. Chamomile is used both internally and externally to treat
I an extensive list of conditions. It is used externally for wounds, ulcers, eczema, j

and leg ulcers. Chamomile's essential oil comprises 0.5% to 1.5% of the flower
head. One hundred twenty chemical constituents have been identified in i
chamomile, including terpenoids, flavonoids and coumarins. [
Marigold oil (Calendula officinalis) belongs to Compositae/Asteracea (daisy) {
family. It is a self-seeding annual with bright yellow or gold flowers that bloom j
from May until October; it grows to about two feet tall with muhiple branches. Its f
leaves and flowers possess many pharmacological activities which include antioxidant,
anti-inflammatory, antibacterial and antiviral. Phytoconstituents isolated j
from this plant are sitosterols, stigmasterols, lupeol, taraxasterol, faradiol 3-0- }
palmitate, quercetin, iso-quercitin and essential oils are rich in mono-terpenes and ;
sesquirepenes. The flowers are the part used medicinally. Calendula oil has many j
potentially useful effects related to compound present in Calendula officinalis I
extract. Among these are anti inflammatory, antiviral, and antimicrobial due to the
terpene alcohols, lactones and flavonoids.
