Study summary

Jing Si herbal tea includes eight Chinese herbs: such as mugwort leaves, fish needle grass, Ophiopogon japonicus, platycodon, perilla leaves, chrysanthemum, and licorice. In vitro, these ingredients were found to be able to block the binding of SARS-CoV-2 and human ACE2 receptor, and further reduce the penetration ability of the virus. Now, Jing Si herbal tea liquid packets have obtained the special license for export from the Ministry of Health and Welfare in Taiwan.

The aim of the study is to investigate (1) the effect of Jing Si herbal tea liquid on blood pressure, blood sugar, and cholesterol in patients with cardiovascular diseases. (2)The human gut microbiota change which is associated with TMAO production (3) The proinflammatory and inflammatory biomarkers change.

We are going to recruit 100 participants from cardiovascular clinics, including patients with hypertension, hyperlipidemia, ischemic heart disease and diabetes, aged 20-75 years old. We exclude those who are cancer patients, have comorbidities with poor control, patients with eGFR\< 40 ml/min/1.73m2, those who are pregnant, breastfeeding, and in their menstrual period when recruiting.

The study has two parts. The first part is a pilot study with 20 subjects all take active Jing Si herbal tea. The second part is a double-blind randomized controlled study with 40 subjects in each arm.
