Noni seeds are vertical, medium-sized, ovoid to obovoid or reniform; wings absent. Noni seeds have been used to make an essential oil.

Characteristics of the noni seed
The noni fruit contains a large number of reddish brown, very hard seeds. Their size is close to that of apple seeds. They are covered in a protective air sac that gives them the ability to float on water for many days.

Traditional harvesting
Noni flowers and fruits year-round. Noni fruit, from which the noni seeds are extracted, are traditionally harvested when they start turning white, or when they have turned fully soft, translucent, and become characteristically odorous. It’s best to choose the riper fruit. Seeds are collected from plants which appear healthy, such as bearing large fruit or showing vigorous leaf growth. [1]

Seed processing
Undoubtedly, ancient Polynesians dug seeds out of the fruit by hand or with sharpened objects; however, as the popularity of noni has increased, a more refined approach has been developed. Once the noni fruit is fully ripe (which can take 3–5 days), the fruit is pressed against a screen or fabric with holes slightly smaller that the seeds. The flesh is removed from the seeds as they are rubbed against the screen. The pulp is then rinsed off and the seeds are ready to be used.

Seeds remain viable even after floating in water for months. Germination is high for fresh seeds, often over 90%. However, seeds can germinate even when thrown on the ground and left unattended. [1]

Traditional uses
Noni seeds were roasted and ingested to help cleanse the body. Records indicate that Tahitians also ate them because of their unique flavor.

Noni seeds were used to make fetid liquid which was rubbed into hair as an insecticide or insect repellent. The same liquid could have been applied to soothe irritated skin.

The seeds of the noni fruit are especially rich in linoleic acid, which is absorbed easily through the skin. Research has shown that linoleic acid, an essential fatty acid, is a powerful ally in skin hydration and health.
