It becomes even more challenging to deal with such health issues particularly for developing countries with limited resources.Further, there is often a social stigma associated with mental disorders and they frequently go unreported and untreated for several years. The problem of neurological conditions is further accentuated due to malnutrition and lack of proper basic healthcare facilities in underdeveloped and developing nations.Alternative medicine and use of medicinal plants may provide a viable and economical option to deal with these prevalent medical conditions. Since long the role of plants has been known to meliorate several diseased conditions.Moreover, due to traditional use history and a positive public perception, particularly with regard to the lesser or no side effects, as compared to modern medicine, makes them a popular choice. Aromatic and medicinal plants have played indispensible role in the human health and disease prevention among human population.Of, species of higher plants known on earth, around have been known to have medicinal properties associated with them. There is growing evidence that essential oils derived from plants have useful therapeutic properties.Inhalation and massages using essential oils of various aromatic and medicinal plants have been a common practice as complementary and alternative medicine. Essential oils are mixtures of volatile organic compounds produced by plants as secondary metabolites.They are considered to have healing properties signicant for both mental and physical health. Essential oils and volatile fractions from many medicinal plants are known to boost brain functioning, relieve stress and anxiety, and treat neuropsychiatric issues.They have been reported to be useful in the treatment of emotional stress and psychological disorders, particularly those associated with the neurodegenerative diseases.

It has been estimated that plant utilizes of their assimilated carbon for the production of volatiles. Also, these volatile emissions are highly regulated in response to changing environmental conditions.Thus, the availability of carbon, nitrogen, sulfur sources, and energy from primary metabolism also regulates the levels of secondary metabolites in any organism. It reduces impurities and improves extraction efciencies.These emissions are responsible for several above ground and below ground effects while released from aerial parts and roots, respectively.They have been reported to play roles in determining the microbiome that inhabits plant surface.Some of these metabolites may serve as energy sources for microbes, while others may exert antimicrobial effects.These chemicals are also reported to aid in plant allelopathic mechanisms and are decisive in determining the consortia of other plants that grow in surroundings. They constitute important UV absorbing compounds, and thus prevent serious photo damage to the plants producing them.They are known to provide thermotolerance to plants.Inhalation of burnt plant parts, fragrances of essential oils, local application, oil steam, and baths are the major practices used in aromatherapy.
