Is this trial a fit for you?
✓Likely a good fit
Ideal participants are people aged 50 or older with a diagnosis of dementia who can complete questionnaires and speak Mandarin or Taiwanese, along with their caregivers aged 20 or older who have provided care for more than six months.
✕Probably not a fit
Patients with renal dysfunction, those judged unsuitable for the herbal tea by a psychiatrist or physician, or those with insufficient cognition to participate are unlikely to benefit from this protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This three-year interventional project will first examine the feasibility of daily Jing Si Herbal Tea use in people with dementia and then measure effects on quality of life and psychosocial health for both patients and their caregivers. In year one, 100 people with dementia will be asked to take the tea twice a day while researchers track adherence and safety. Outcomes will include standardized quality-of-life and sleep questionnaires for patients and validated measures of caregiver burden and psychosocial well-being. The protocol excludes people with renal problems or those deemed unsuitable by a clinician, and data collection will occur at participating hospital sites.
Why it matters
Potential benefit: If successful, regular use of Jing Si Herbal Tea could improve sleep, quality of life, and psychosocial well-being for people with dementia and reduce caregiver burden.
How similar studies have gone: Some animal studies and clinical reports have suggested benefits of Jing Si Herbal Tea for conditions like aging, depression, and sleep, but its effects specifically in dementia patients and their caregivers remain largely untested.
