Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A total of 912 participants will be recruited from 9 clinics. 2\~3 clinics will represent a cluster unit. The stepped wedge design will consist of four groups each containing four randomly allocated cluster units, allocated to either 4, 8, 12, or 16 weeks of the intervention. The intervention is Chinese herbal teabag treatment, which will consist of five Chinese herbs (a total of 10g). The first group will receive 16 weeks of the intervention, the second group will receive 12 weeks, the third group will receive 8 weeks, and the forth group will receive 4 weeks.
The primary outcome measure is the stroke risk estimated with Automatic Retinal Image Analysis (ARIA). Secondary outcome measures include Framingham Stroke Risk Score (FSRS), cognitive impairment risk estimated with ARIA, Hong Kong version of the Montreal Cognitive Assessment (MoCA), Constitution in Chinese Medicine Questionnaire (CCMQ), World Health Organization Quality-of-Life Scale (WHOQOL-BREF), Health-promoting lifestyle profile II (HPLP-II), and adverse events.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Chinese Herbal Medicine (CHM) teabag, Cluster 1
Intervention Cluster 1 is the first intervention arm designed to examine the efficacy and safety of CHM teabag in decreasing stroke risk by machine-learning-based retinal image analysis in elderly population. It will receive 16 weeks of the intervention.
Chinese Herbal Medicine (CHM) teabag
Each teabag contains five herbs: Radix et Rhizoma (三七, Sanqi), Moutan Cortex (牡丹皮, Mudanpi), Puerariae Lobatae Radix (葛根, Gegen), Rosae Rugosae Flos (玫瑰花, Meiguihua), and Citri Grandis Exocarpium (化橘紅, Huajuhong). These herbs are benefit to promoting blood circulation, dredging meridians and collaterals, strengthening spleen, regulating qi and decreasing phlegm in Chinese Medicine theories.
CHM teabag, Cluster 2
Intervention Cluster 2 is the second intervention arm designed to examine the efficacy and safety of CHM teabag in decreasing stroke risk by machine-learning-based retinal image analysis in elderly population. It will receive 12 weeks of the intervention.

CHM teabag, Cluster 3
Intervention Cluster 3 is the third intervention arm designed to examine the efficacy and safety of CHM teabag in decreasing stroke risk by machine-learning-based retinal image analysis in elderly population. It will receive 8 weeks of the intervention.
