This tree is called máii in Chuukese, the fruit is what Kón (pounded breadfruit) is made out of. Preparing a Kón is pretty easy if you just think about it but it's actually a little tiring when you do it because you have to peel it first, cook it until it is fully cooked, and then you pound it until the breadfruit is fully pounded and kinda spongy (Chuukese call it mén) then you can wrap it or put it in a container and put coconut milk on it if you want.

This plant is called beach naupaka because it is mostly found on the shoreline. This plant can be used in many kinds of way, especially healing. The fruit of this plant is used for pinkeye, the juice inside the fruit cleans the eyes. For the ladies, they can get even numbers of the leaves (2, 4, 6 or how many you want ) pound it, mix it with water then you squeeze it in a cup and drink it. That is to clean out the female part.

Will clean up photos later. In field. Sorting out I. littoralis versus possible I. indica indentification. Related to the discussion on https://www.inaturalist.org/observations/149455325 This is not the exact same plant, this is about twenty meters away from the other plant. All of these are identified locally as omp.
[omp, also emp₂. n. vine sp., Ipomoea littoralis, the leaves of which are used in medicine and for magic.
http://www2.hawaii.edu/~rehg/pnp-o.htm] Ipomoea indica is said to be "densely hairy with short, soft trichomes, the top is more or less sparsely hairy." [https://en.wikipedia.org/wiki/Ipomoea_indica] I am not seeing that in this plant here. I realize that this appears to be far from the ocean, but Pohnpei is only 12 miles across, the whole island is essentially coastal. Both I. littoralis and I. indica are recorded in Checklist of the Vascular Plants of Pohnpei, Federated States of Micronesia with Local Names and Uses. Herrara, Lorence, Flynn, and Balick. Allertonia, National Tropical Botanic Garden, Volume 10, October 2010.
but I. indica has a local name of iol wah poh mehi. I. indica also has a more distinctly blue inflorescence.

Pohnpeian people call this “weipwul” and it is a very useful plant . This plant can cure fever and also good for high blood pressure.
Fever: take like 4 or 5 leaves of the plants and make it a little hot and put them on your skin.
High blood: take 4 leaves of the plant and also the fruit from the plant and smash them together and fill up a cup with water and then put them inside and drink it .

This is a noni tree, and we call it Weipwul in our language. It is very important for us Pohnpeians, because it is a healing plant. There are 3 parts of the tree that can be used for healing, the root, the leaves and the fruits. The root can be used for those who have toothache, it can help in reducing the pain but for some it can help to overcome the pain. When using the root, you will get it from the ground, clean it then you break it down to small pieces, you put it on a piece of cloth, and put it on your tooth, or where you are feeling the pain. You can also boil water with salt and mix it with the piece of cloth that holds the root you got from the ground For the fruit , we will bound it then drink it, you can also eat the small ones and it can overcome stomachache, headache, diarrhea, and more.. For the leaves we can use it for imwilap or you boil a water , put it in a pot and you put the leaves inside and you get a blanket to cover yourself. It can help in overcoming headache and coughing as well.

This plant is called Noni. My people of Kosrae call it II and we use it as a healing plant. We use the yellow leaves to help people with cancer by boiling 12 of the yellow leaves and steam bath with it or it’s better if the person drinks it. The green leaf is used mostly for detoxifying the body or helping people strengthen our kidney by boiling and drinking or pounding the leaves and drinking it daily. The fruit itself is used on mostly ladies that just gave birth. The fruit is to be boiled and after boiling the ladies that just gave birth shower with it to help cleanse their private area. The baby leaves, the ones that just grew are good for people with boils. We take the baby leaves, pound it and mix with local oil then place it on the boil.
