R.S.: The medicinal action of etheric oils (rosemary), consists in stimulation of the ego. Tannins make the astral body inclined to combine with the etheric body. Bitter substances stimulate the etheric body to take the astral body into itself.

Terpenoids and Essential Oils

Plant fragrance is carried in the so-called essential oil component. These oils are secondary metabolites that are highly enriched in compounds based in isoprene structure (Marjorie, 1999). They are called terpenes and their general chemical structure is C10H16. If the compounds carry an additional element, usually oxygen, they are called terpenoids. Terpenoids are synthesised from acetate units and as such they share their origin with fatty acids (Marjorie, 1999). They differ from fatty acids in that they have extensive branching and they are cyclized. Some examples of

common terpenoids include methanol and Camphor (monoterpes), farnesol and Artemisin (sesquiterpenoids) (Marjorie, 1999).

Terpenoids are reported to be active against bacteria (Ahmed et al., 1993/Akpata and Akinrimisi, 1977). In 1977, it was reported that 60% of essential oil derivatives examined to date were inhibitory

to fungi while 30% inhibited bacteria (Chaurasia and Vyas, 1977). It is speculated that the mode of action of the terpenes revolves around the membrane disruption by the lipophilic compounds

(Marjorie, 1999). Food scientists have found the terpenoids present in essential oils of plants to be useful in the control of Listeria monocytogenes (Aureli and Zolea, 1992).

Terpenes are a class of hydrocarbons usually produced from plants. They are the building blocks of many essential oils used in perfumes and other fragrances.
