Convolvulus prostratus, also known as Shankhpushpi, has a long history of use in traditional Ayurvedic and Unani medicine as a "medhya rasayana" (brain tonic). It is commonly prescribed to support cognitive function, including the treatment of confusion, memory loss, and mental fatigue. Classical texts describe its use to improve intellect, memory, and clarity of mind, and it is often included in polyherbal formulations for enhancing mental performance and alleviating symptoms associated with mental stress or confusion.

Scientific validation for these uses is limited. Some preclinical studies (primarily in rodents) have suggested that extracts of Convolvulus prostratus may possess nootropic, anxiolytic, and neuroprotective properties, potentially due to its antioxidant activity and modulation of neurotransmitters such as acetylcholine. However, robust clinical trials in humans directly evaluating its efficacy for confusion or cognitive impairment are lacking. The majority of evidence remains anecdotal or is derived from traditional medical systems.

In summary, while traditional use as a remedy for confusion is well-documented, high-quality scientific evidence to support this application is currently weak. The rating reflects strong traditional support but only preliminary scientific exploration.
