West BJ, Deng S, Palu AK, Jensen CJ.
A carbomer gel base, containing the noni leaf extract and noni leaf juice was not allergenic in a repeat-insult patch test with 49 adult volunteers. The gel also mitigated UVB-induced erythema in 25 adult volunteers. Noni leaf extract also demonstrated potential anti-inflammatory properties in a histamine H-1 receptor antagonism assay.
