The Effect of White Tea in Healthy Human Subjects
Sponsor: Universitas Padjadjaran
Summary
This clinical study aims to determine the effects of consuming white tea infusion (Camellia sinensis) on healthy subjects over a period of 14 days. The main questions it aims to answer are: 1. Determine the effect of white tea consumption on the anthropometry of healthy subjects. 2. Determine the effect of white tea consumption on the biochemical parameters of healthy subjects. 3. Determine the effect of white tea consumption on hematology parameters that are related to anemia case in healthy subjects. 4. Determine the effect of white tea consumption on the activity of first-line antioxidant enzymes in healthy subjects Researchers used only one treatment group, and respondents knew which treatment they would receive (single-arm and open-labelled), namely white tea infusion to maintain human body health. Participants will: 1. Follow the washout stage for 7 days 2. Drink white tea infusion every day for 14 days. 3. Follow up to monitor adverse effects after consuming white tea; this stage will be conducted for 7 days. 4. Report all food and beverages consumed by respondents during the study.
