Essential oils now form a part of day-to-day life of people. There are different varieties of essential oil used for fragrance and flavours. The quality and composition of these oils play an important role in determining their role in therapeutics. The present paper gives an account of the medicinal plants containing essential oils and their therapeutic properties. Different oil yielding plants were surveyed to find out the efficacy of essential oils in disease treatment.

Key words: Oil yielding plants, essential oils, therapeutic properties,


       Many developing countries are economically based on production of essential oils (Husnu, 1999). India has increased the production of a number of essential oils and the same have become more affordable, yet common man still maintains it to be the domain of the rich and the affluent. Man has shown interest in the diverse and fragrant odours associated with certain plants form the beginning of his history. The fragrance derived from plants is oily in nature and particular odour and smell of plants are due to compounds known as essential oils. A number of recent studies appear to suggest that certain essential oils may be effective in preventing the spread of the organism. Essential oils are found in all distinctly aromatic plants. These oils contain several aromatic compounds having the six-carbon ring characteristic of the benzene series and related organic groups. Some oils help in healing wounds. These oils have efficacy to cure various dermatological problem (Marwah and Marwah, 2003). Essential oils can play a crucial role in providing a solution to most of these problems created due to falling environmental condition and other related reasons.

      Essential oils can prevent contagious and infections diseases (Marwah and Marwah, 2001). These oils have a calming, stimulating, pain alleviating and mood enhancing effect. They improve the functioning of internal organs, like heart, lungs etc. Till now they were on the periphery of pharmacological preparations, but now used extensively as carminatives, antiseptic, analgesics, anti-inflammatory and flavouring agents. This is because they have multiple beneficial effects than just being pain relievers (Shukla and Shukla, 1997). Essential oils have excellent therapeutic properties to cure various common problems of human beings (Chowdhury, 2003). They have very good medical properties and their constituents are beneficial for human beings (Bouillet and Goeb, 1999).

       Essential oils have long been recognized because of their anti-microbial activity (Deans and Ritchie, 1987; Paster et al., 1990; Reddy et al., 1991; Lis-Blachin et al., 1998; Smith-Palmer et al., 1998; Hammer et al., 1999). Due to this property, essential oils have gained much attention in investigations on their potential as alternatives to antibiotics for therapeutic purposes and applications in the cosmetics and food industry.

The present investigation was carried out to assess the efficacy of essential oils in therapeutics and in curing some common problems of human beings. 


     During the present investigation various oil yielding plants were surveyed in different places during 2006-2007. Their therapeutic properties were investigated from the local medicinemen who prescribed their own herbal preparations. Relevant information on disease treatment by the plants has been collected from the elderly persons of the local community in these areas. The collected oil yielding medicinal plants were identified with the help of floras and the informations were further verified by crosschecking with the medicineman of different parts of the India together with authentic journals and books.

Results and Discussion

      Essential oils are one of the most beneficial bio-product. These oils are now being used extensively to cure various dermatological and other related human diseases.
