Laboratory & animal research
Lab and animal results show what might be worth studying in people. They don't show that the herb has these effects in humans.
In rats with a model of Parkinson's disease, siris extract improved movement and endurance and restored the brain's antioxidant defenses.[2]Study
Research in people
A 2026 systematic review of 17 studies found the bark and leaves reduced inflammation and acted like antihistamines. In clinical studies, people with asthma who took stem bark preparations breathed better. Better trials are needed.[1]Review or trial
