Tupelo is a delicious honey. It does not granulate ever. That is its property. If the honey crystallizes, then this is not pure Tupelo honey. It is high in laevulose sugar. This sugar bypasses the liver and pancreas and does not cause wide swings in mood, blood sugar, or a rise cholesterol. It was first harvested by the Muskogee Creek Indians now in reservations in the state called Oklahoma. Most tupelo honey is from the South East United States: Florida, North Carolina, Georgia regions of the USA. Tupelo honey bees harvest the nectar from flowers high on the black gum tree, nyssa aquatica, white flowers. It seems fine for a cystic liver.

While living in 10º below zero weather in Virginia tupelo never granulated. I have read that the health benefits of tupelo honey are destroyed by heating. All tupelo honey is raw honey. Try to visit the apiary and speak with the bee keepers. The tupelo flower is very delicate and it blooms for only a very short time each year.

Tupelo gum tree grows in swamps and floodplains in the south, where the soils are periodically flooded and the roots are under water for part of the time. It grows along the coastal southeastern U.S.A. from southeastern Virginia to Georgia, west across northwestern Florida along the Gulf of Mexico to southeastern Texas and extends up the Mississippi. It reaches its northern limit in the extreme southern tip of Illinois, where it occurs commonly growing amongst Cypress trees in the swamps.
I found only one source who thought the black gum tree was found to be growing in the Philippines in Davao. If you can find a source for local honey this is best, i.e. Linden Flower honey in the UK. Ask what local honeys do not granulate. Here in Hawaii we have Kiawe honey. It is a white honey and oh so delicious.
