Conditions
Brief summary
The aim of this study is to investigate the efficacy and safety of Tian Jiu in the treatment of allergic rhinitis compared with placebo and waitlist patients in Hong Kong.
Detailed description
This will be a prospective, randomized, single-blinded, controlled trial in patients with AR. After a one-week run-in period, eligible subjects will be randomly assigned to the Tian Jiu group, placebo-control group and waitlist-control group. The TJ and placebo-control groups will undergo a 4-week treatment with one session per week and one 4-week post-treatment follow-up. Participants in the waitlist-control group will not receive any treatment during the first 4 weeks but will be required to be assessed. The total study period will be nine weeks.
