[What is Huperzine A]

Huperzia is a type of moss that grows in China. It is related to club mosses (the Lycopodiaceae family) and is known to some botanists as Lycopodium serratum . The whole prepared moss was used traditionally. Modern herbal preparations use only the isolated alkaloid known as huperzine A. Huperzine A is an alkaloid found in huperzia that has been reported to prevent the breakdown of acetylcholine, an important substance needed by the nervous system to transmit information from cell to cell. Animal research has suggested that huperzine A’s ability to preserve acetylcholine may be greater than that of some prescription drugs. Loss of acetylcholine function is a primary feature of several disorders of brain function, including Alzheimer’s disease . Huperzine A may also have a protective effect on brain tissue, further increasing its theoretical potential for helping reduce symptoms of some brain disorders.

[Function] Used in alternative medicine, huperzine A has been found to act as a cholinesterase inhibitor, a type of medicine used to prevent the breakdown of acetylcholine (a chemical essential to learning and memory).

Not only used as a treatment for Alzheimer’s disease, huperzine A is also said to enhance learning and memory and to protect against age-related cognitive decline.

In addition, huperzine A is sometimes used to boost energy, increase alertness, and aid in the treatment of myasthenia gravis (an autoimmune disorder that affects the muscles).

Researchers from the University of Florida are using genetic engineering to make purple limes.

Purple limes could be the future of the Sunshine state’s citrus crop, say researchers from the University of Florida. 

They’re doing it via genetic engineering.

According to a press release, “These modified Mexican limes have a protein that induces anthocyanin biosynthesis, the process that creates the ‘red’ in red wine, and causes the limes to develop a range of colors in the pulp from dark purple to fuchsia.” 

One of the researchers, Manjul Dutt, noted, “Anthocyanins are beneficial bioflavonoids that have numerous roles in human well-being. Numerous pharmacological studies have implicated their intake to the prevention of a number of human health issues, such as obesity and diabetes.”

Anthocyanins occur naturally in the blood oranges of Spain and Italy where colder weather leads citrus to naturally develop much darker colors than Florida’s subtropical climate would normally allow.

The purple limes of Florida, however, have been tinged with anthocyanins gathered from the genes of “Ruby Seedless” red grapes and “Moro” blood oranges. 

And, researchers note that with a little tinkering, they can control the color of the limes’ flowers and stems in order to create ‘ornamental’ plants.
