Boswellia vs standard medicine for root canal infection
This trial tests whether a natural gum resin (Boswellia) placed inside the tooth during root canal treatment can fight infection better than standard medications. It may be a good option for people with a single-rooted tooth infection who are otherwise healthy.
Al MansurahAges 20–60 - NCT06466707Recruiting
Collecting gut bacteria samples from healthy volunteers
This study collects stool or other samples from healthy people to learn more about the helpful bacteria in our gut. It may help researchers understand how these bacteria affect health.

- Yes. Clin2 currently lists 442 recruiting colonization studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a colonization trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a colonization trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
