What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

ayahuasca or esketamine

What this could lead to

If it works, this could point toward a new, fast-acting treatment option for PTSD that uses a single dose.

What could go wrong

This is a very small early-phase trial with only 10 participants, so results may not apply widely. Both substances can cause intense psychological effects and are not proven safe or effective for PTSD yet.
