GENERAL IMMUNITY

Noni

Morinda citrifolia

also known as noni fruit

Weak (modern) / moderate (traditional Pacific)

A tropical fruit with a strong, cheese-like smell, central to Polynesian medicine for two thousand years. Traditional use covers a wide range of conditions, from digestion to immunity to pain. Modern clinical evidence is limited and the marketing has often outrun the science.

Traditionally associated with energy, immunity, joint discomfort, and digestion
Antioxidant action from compounds in the fruit and leaf
Antimicrobial activity in lab studies
Modern clinical evidence is limited; most research is preliminary or industry-funded

Marketing claims for noni have been the subject of FTC enforcement — credible reference works treat the bigger claims with skepticism
