Clinical Trial Summary

The primary research objective of this study is to confirm the absence of side-effects and explore any analgesic properties of the botanical formulation TGIR (Traditional Gastrointestinal Remedy) in healthy participants.

Description:

This study is a randomized, placebo-controlled, crossover, clinical trial with 24 healthy volunteers. Participants will be randomized to receive each of the two treatments, TGIR (500mg/capsule, total 1.0g) followed by Placebo (2 matching capsules), or vice-versa, with a week between treatments. Participants will remain in the clinic for a 4-hr observation period each day for a total of 2 clinic visits. During the course of treatment, participants will receive physiological monitoring: heart rate and blood pressure. Any adverse events and side effects will be documented throughout the study, in addition to participant feedback and perceived effects. On each day of treatment (TGIR and placebo-control), participants will receive a standardized test of analgesia using Brief Thermal Sensitization (BTS) and measures of reaction time using a computer-based Psychomotor Vigilance Task (PVT).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Standardized heat sensitivity testing - Brief Thermal Sensitization (BTS)	Participants rate the painfulness of the heat stimulation on a paper 100 mm Visual Analogue Scale anchored with the descriptors "no pain" (0 mm) and "worst pain imaginable" (100 mm).	30-60min post-treatment
Primary	Measure of reaction time - Psychomotor vigilance task (PVT)	PVT performance on a computer-based test measures lapses, defined as reaction times exceeding 500 msec or failure to react.	60min post-treatment
Secondary	Physiological monitoring - Heart rate	Heart rate monitoring	Recording every 30min over 4 hours post-treatment
Secondary	Physiological monitoring - Blood pressure	Blood pressure monitoring	Recording every 30min over 4 hours post-treatment
