The mode of action of lavender oil in brain functioning is proposed to be related to the intensication of antioxidant defense like rise in the activities of superoxide dismutase caused by its active biomolecules. Neurological effects of lemon oil treatment are very well studied.Balm tea is known for affecting numerous behavioral aspects by modulating brain functioning.It is effective against seizures, headaches, insomnia, and epilepsy. Lemon balm acts as a neuroprotective agent of cognitive and behavioral dysfunctions by inhibiting acetylcholinesterase enzyme. The memory improving effects of the plant are also experimentally proved is known to possess numerous volatile compounds, mainly menthol, menthyl acetate, neomenthol, menthone, isomenthone, menthofuran, pinene, pinene, limonene, and, cineol. Essential oils from mint are known to effectively relax mental fatigue and possess psychoactive potential. Aroma of peppermint enhances concentration and helps in improvement of working memory, virtual recognition memory, and visualmotor responses. The hot water infusions of leaves of peppermint have been shown to affect motor coordination, behavior, motility, and barbiturate induced sleep in mice. Consumption of peppermint tea suggests its analgesic and sedative effects on the central and peripheral nervous system. Peppermint oils relieve from headache and migraine issues and show antidepressant effects. Inhalation of oral essence of roses inuences physiological and psychological behaviors. Rose oils are reported with hypnotic, anxiolytic, and anticonvulsant properties. Rose essence and extracts are known to treat epileptic seizures and prevent the formation of dark neurons in hippocampus regions in pentylentetrazol. In stressed rats, olfactory stimulation by rose essential oils was reported to inhibit stressinduced hypothalamic paraventricullar nucleus activity and hypothalamopituitaryadrenocortical axis activation. Clinical trials have shown that the application of rose oil improves sexual dysfunctioning in males suffering from depression. A research carried on a group of secondary school students with essential oil of rosemary had shown positive inuence of inhalation on memorization of images and numbers. It suggests the possible role of the plant for the treatment of depression and stress. The low doses of rosemary are also reported to be effective in enhancements of memory and cognition abilities over a long time. The olfactory stimulation with rosemary oil improves mental health, cognitive performance and relaxes from anxiety.Aromatherapy massages using the oils of rosemary positively modulate mood and selfesteem.

Sandalwood constituents are reported to affect central nervous system by effectively increasing the concentrations of homovanillic acid, dihydroxyphenylacetic acid, andor hydroxyindoleacetic acid in the brain of mice. It contains numerous volatile active constituents of which endoborneol and borneol are most abundant. The inhalation causes sedative effects, inhibits lipid peroxidation, and is effective for epilepsy and convulsions. SHXW inhalation shows excellent antidepressant and anxiolytic properties. It possesses antioxidative effect and suppresses apoptosis.To nd novel psychoactive drugs, studies are needed to nd out the mechanism of action of active plant constituents, particularly responsible for neuroprotective and neuroregenerative potential of various medicinal herbs.
