Noni juice reduced the number of inflammatory cells in the lungs of OVA-sensitized rats. It also had a dose-dependent nitric oxide scavenging effect and inhibited (up to 90%) calcium and cholinergic induced spasms of jejunum segments. Noni juice demonstrated chronic anti-inflammatory activity in sensitized lungs as well as a spasmolytic effect involving calcium channel blocker activity.
