Objectives of Study:

The study on the clinical efficacy evaluation of the Tanyutongzhi antihypertensive decoction in intervening with the normal high blood pressure population aims to scientifically assess its therapeutic effects on this group providing high-quality clinical evidence for the application of traditional Chinese medicine in the prevention and treatment of hypertension.

Description for medicine or protocol of treatment in detail:

Inclusion criteria

1. Subjects voluntarily participate and sign the informed consent form; 2. Age range: 18 years old ≤ age < 65 years old; 3.

Randomization Procedure (please state who generates the random number sequence and by what method):

The statistician will use R software to generate random numbers for both subject randomization codes and drug blinding codes. Stratified block randomization will be employed for the random numbering process. The subject randomization codes and drug blinding codes will then be imported into Excel software for management.

Blinding:

Double-blind: Each study subject is assigned a blinded drug coding and this coding is marked on the outer packaging of the dispensed drugs. Based on the randomization results personnel unrelated to the study will fill the drug packages with either the investigational drug or placebo which are labeled with the blinded coding. The blind codes are sealed and kept by both the statistician and the principal investigator.

IPD sharing:

No

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):
