Published25 Feb Abstract Oral administration of an aqueous extract of the aerial parts of Bromelia karatas to STZ-NA rats showed a significant hypoglycemic effect in a chronic trial lasting 42 days. Isolation and identification of the compounds present in the extracts were accomplished by means of various conventional chromatographic and spectroscopic techniques. Introduction Diabetes mellitus is a metabolic disease that is characterized by elevated levels of blood glucose that over time cause serious damage to the heart, blood vessels, eyes, kidneys, and nerves [ 1 , 2 ]. Individuals with Type 2 diabetes typically suffer from insulin resistance and relative rather than absolute insulin deficiency. At least initially, and often throughout their lifetimes, these individuals may not require insulin treatment to survive.

When I can combine the two out hiking and exploring I am a happy camper! The most common and popular edible bromeliad is the pineapple Ananas comosus But there are other bromeliads that are also great food sources. Several species in the genus Bromelia have their fruit technically a berry harvested and eaten. Bromelia karatas produces its flowers and berries tucked down in the rosette of leaves.
Above is a particularly massive head of berries. To the left is probably a bit more typical. When ripe, the berries should have good color and pop off with just a little wiggle. They will range in color and the bottom half may still be white, but they still should be ripe. The berries usually have a bit of the fuzz left on from the inflorescence.
It should be easy to rub off making the skin of the berry shiny. I find it easiest to bite the stem end of the fruit and start peeling it back like the skin of a banana. Biting into them is almost like crunching a slightly crisp and tart watermelon remember to mind the seeds!
The flavor is fairly strong with a tart and astringent aspect. Sometimes they are available in the markets when they are in season and harvested and I look forward to the opportunity to taste the drink that is made from them.
A terrestrial bromeliad, up to 3 m tall, distributed from southern Mexico and the Caribbean south to Brazil, Colombia and Ecuador, where it grows in savanna s, scrublands and deciduous forests, at elevations up to m. It forms rosettes of upright, lanceolate leaves with sharp spine s along the margins, bright green above and grayish green below. As the plant matures, the leaves closer to the center of the rosette change their color to red while the ones at the exterior remain green. It develops an inflorescence with a multitude of pink-purple flower s with a whitish base, followed by juicy, edible fruits covered by a yellowish-brown husk. The fruits are traditionally used to prepare a delicious, refreshing drink called "Atol de Pina" and are much appreciated for their appealing, sweet-sour taste. The fruits ship well and are now being considered as a potential new crop for larger scale production.
