CHEMICAL COMPOSITION AND PROPERTIES

Dried Ocimum basilicum (common basil) leaves contain a minimum of 0.25% essential oil, depending on the cultivation conditions the content varies and can reach 2% of the dry weight.

Basil essential oil composition :

- Indian Ocean basil contains mainly estragole with other terpenes in small quantities (cineole, fenchol, linalool and methyl eugenol);
- European basil contains more linalool or methyl eugenol.

Ocimum micranthum and gratissimum contains comparatively more essential oil, up to 5% of the dry weight, whose composition also varies according to the geographical origin or the cultivar:
- in Africa thymol dominates,
- in the Pacific regions and south-east Asia eugenol is predominant.

The properties of essential oils , are related to their chemical composition and therefore variables:

- Eugenol and methyl eugenol are anti-inflammatory, slow platelet aggregation , locally anesthetic and antibacterial ,

- the other terpenes regulate digestive functions: eupeptic, carminative, anti-gastralgic and antispasmodic.

In aromatherapy the basil essential oil is described as a sympathomimetic.

Some components of basil essantial oil are potentially toxic:

- estragole has been shown to be hepatocarcinogenic in mice,

- and some estragole derivatives are even more toxic.

As always, we should not consider essential oils as harmless drugs.



USES

The common basil is mainly a spice used very fresh and not cooked.

Ocimum in general are used in perfumery (especially flowers), for example: " Miri Monoi" in Polynesia.

The basil tea ( infusion of fresh leaves) :

- calms gastric pains, digestive migraines, dyspepsia in general,

- it is a tonic by adrenal stimulation,

- slightly diuretic,

- useful in cases of viral fever ("flu-like" affections, common fevers),

- and post-infectious "fatigue".

The tea of ??Ocimum micranthum and gratissimum (infusion of fresh leaves and flowers) is also diuretic and anti-dyspeptic but the presence of eugenol in quantity makes it less pleasant.

Ocimum gratissimum essential oil in oral hygiene and in dentistry :

- application with a cotton pad , directly on the decayed or painful tooth (waiting for a proper treatment),

- mouthwash and gargle in case of gingivitis or angina, a few drops of essential oil in a glass of warm water.

More anecdotal, some therapists advocate:

- the concentrated decoction of basil in application to fight against hair loss and to calm the bites of insects,

- powder of dried basil leaves in case of chronic rhinitis, 1 pinch morning and evening,

- the juice obtained by the expression of 2 to 3 fresh and crushed leaves serves as eye drops, it is applied directly on the irritated eye (South America and West Indies),

- often in case of fever, Amazonian Indians use balneotherapy with an infusion of plants; they consider Ocimum gratissimum as the best febrifuge for external "washing", especially in children.
