[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).

What are steviol glycosides?
You have the stevia growing on the ground, it has a little green stevia leaves and in fact we don’t eat or even chew on that whole leaf. Many hundreds of years ago people on south America really did chew on a whole leaf and you certainly can. But if when we look at putting stevia into baked goods or into yogurt or into some kind of ice tea or beverages we want to get the peace of the leaf that’s really delivering the sweetness. And it turns out when you look at leaf there are lot of this different compounds called steviol glycosides – some sweeter than the others..some are earthiness than the others do in terms of the flavor profile it’s a plant, a natural plant that’s gonna have some variability. So we look at the leaf we figure out which steviol glycosides is really delivering the kind of sweetness for a certain product that we want to develop and we isolate that particular glycosides.
