An Herbal Nasal Drop Enhanced Frontal and Anterior Cingulate Cortex Activity

الملخص EN

The present study examined the neuro-electrophysiological activity of the brain associated with the application of a herbal remedy developed by a Shaolin monk based upon the Chan healing principle of clearing the orifices (i.e., the nasal cavities).

A repeated-measures design was used.

Fourteen normal adults were administered herbal remedy and saline solution intranasally on separate sessions.

Two intervals of eyes-closed resting EEG data were obtained individually before and after each administration.

Results showed that only the herbal remedy but not the saline solution induced elevation in cordance, an index correlated with cerebral perfusion, in the anterior brain region.

In addition, the activity of the anterior cingulate cortex (ACC), as examined by the LORETA analysis, was also increased after the application of the herbal remedy but not saline solution.

The present study provided some preliminary evidence suggesting that the herbal nasal drop enhanced the activity of the frontal lobe and ACC.

Implications for the potential clinical application of the herbal remedy to treat patients with frontal lobe disorders were discussed.
